*活性離子接地極

產(chǎn)品描述:

*活性離子接地極尤其適用于各類有較高接地要求、接地工程難度較大的場(chǎng)所,與傳統(tǒng)的接地方式相比較,能使雷電沖擊電流及故障電流更快地?cái)U(kuò)散于土壤中,因此,在惡劣的土壤條件下,接地效果尤為顯著。 *活性離子接地極所應(yīng)用的保濕配方、離子緩釋、潛深接地、*降阻四項(xiàng)前沿科技zui大程度解決了降阻性、耐腐性和使用壽命等問(wèn)題,使得該產(chǎn)品在各項(xiàng)接地性能和適應(yīng)性方面具有明顯優(yōu)勢(shì),應(yīng)用領(lǐng)域十分廣闊。

突破土壤的限制--*活性離子接地極包含的回填材料具有非常好的膨脹性、吸水性及離子滲透性,通過(guò)毛細(xì)原理實(shí)現(xiàn)水分保留。無(wú)論天氣或周圍環(huán)境如何變化,都能使周圍土壤保持一定的濕度,以達(dá)到*的導(dǎo)電狀態(tài),且能隨著時(shí)間的推移,逐漸擴(kuò)大周圍土壤的導(dǎo)電范圍。適用于不同的地質(zhì)條件,在黑土、黃土、鹽堿土、垃圾土、回填土、風(fēng)化沙土、細(xì)沙土、黏土、山地通過(guò)優(yōu)質(zhì)的施工工藝均能達(dá)到良好的接地降阻效果。

*科技及材料--*活性離子接地極由*的可逆性緩釋化合物組成,電極外表是紫銅合金,以確保zui高導(dǎo)電性能及較長(zhǎng)使用壽命,并配以內(nèi)外兩大種類填充劑。經(jīng)實(shí)驗(yàn)證明,土壤電阻率過(guò)高的直接原因是因?yàn)槿狈ψ杂呻x子的輔助導(dǎo)電作用。接地導(dǎo)體外部的填充劑是以具有強(qiáng)吸水力,強(qiáng)吸附力和陽(yáng)離子交換性能高的材料為主體,配以*、降阻、防腐功能強(qiáng)、膨脹系數(shù)高不受溫度變化影響、耐高電壓沖擊的多種化學(xué)材料為輔料。主要用于解決接地導(dǎo)體周圍的濕度、離子生成含量、防腐保護(hù)等問(wèn)題,使導(dǎo)體與大地緊密結(jié)合,從而降低了電極與土壤的接觸電阻,改善了周邊土壤的電阻率,有效地增強(qiáng)了雷電導(dǎo)通釋放能力。導(dǎo)體內(nèi)部填充材料含有特制的電離子化合物,能充分吸收空氣中的水分。通過(guò)潮解作用,將活性電離子有效釋放到土壤中,與土壤及空氣中的水分作用,更加促進(jìn)導(dǎo)體外部緩釋降阻,且保持阻值*穩(wěn)定。導(dǎo)體內(nèi)部的化合物,隨時(shí)間的延長(zhǎng)逐步化合成膠質(zhì)透明狀態(tài)。我們利用膠質(zhì)化合物的導(dǎo)電性能,使整個(gè)系統(tǒng)能夠*處于離子交換的狀態(tài)中,從而構(gòu)成了理想的電解離子接地系統(tǒng)。 導(dǎo)體內(nèi)的緩釋填充劑埋設(shè)后,接地電阻會(huì)逐漸下降,半年至一年內(nèi)達(dá)到穩(wěn)定值,埋設(shè)緩釋過(guò)程可以長(zhǎng)達(dá)30年。

接地系統(tǒng)原理--接地裝置的接地電阻通常由三部分組成(

                                               

*部份:接地體本身的電阻,通常接地電極都是用金屬做成,這部分電阻只占接地電阻的1%-2%,可以忽略。

第二部份:接地電極與土壤接觸部分的接觸電阻,這部分電阻是由接地極與土壤的接觸面積決定的。

第三部份:電流流經(jīng)接地極流入土壤后散流時(shí)的電阻,這部分散流電阻由土壤電阻率決定。

接地電阻組成:

散流電阻, 10-20%, 20-40%, 40-70%, 70-90%

研究表明:接地電阻的大小決定于電極周邊的土壤類型。接地電阻可以用接地體周圍等厚度圓柱型土壤殼層來(lái)表示,如果土壤電阻是均勻的,則絕大部分電阻分布在直接圍繞接地體的殼層上,因此,接地電阻一般都在接地體周圍半徑1.5-3米范圍內(nèi)。*活性離子接地極在接地極中加入可逆性緩釋填充劑。這種填充劑具有吸水、放水、可逆的特點(diǎn)。當(dāng)它吸水時(shí),可以吸收自身100-500倍的水分,當(dāng)外部環(huán)境干燥缺水時(shí),又可以*釋放擁有的水分,達(dá)到周邊水分平衡,這種可逆反應(yīng),有效保證了殼層內(nèi)環(huán)境的有效濕度,保證了接地電阻的穩(wěn)定。通過(guò)這種方式產(chǎn)生的離子吸收大地水分后,可以通過(guò)潮解作用,將活性電解離子有效釋放到周圍的土壤中,使接地極成為一個(gè)離子發(fā)生裝置,從而改善周邊土質(zhì)使之達(dá)到接地要求。接地極外部填充劑通過(guò)與其內(nèi)部電解離子填充劑的相互作用產(chǎn)生針對(duì)殼層土壤的化學(xué)處理,降低殼層土壤的電阻率,同時(shí)在緩釋接地極與大地土壤之間,形成了一個(gè)過(guò)渡帶,增大了接地極的等效截面積和土壤的接觸面積,消除了接地體與土壤之間的接觸電阻,改善了地中的電場(chǎng)分布,填充劑良好的滲透性能,深入到泥土及巖縫中,形成樹(shù)根網(wǎng)狀,增大了地中的泄流面積

深水資源CP系統(tǒng)

產(chǎn)品描述:


Product Overview

The SmartPod system is an inligent version of Deepwater's well-proven RetroPod? cathodic protection system for offshore platforms. The system greatly simplifies deep water cathodic protection by providing a modular anode structure with on-board status-monitoring, using Deepwater's patented SunStation? cathodic protection monitor technology (each unit contains 3 SunStation monitors).

Each SmartPod can protect a number of discrete subsea structures and can be configured to provide 20 years of cathodic protection to over 25,000 square feet of coated steel.

RetroClamps allow an ROV to connect to the subsea structures, and Polatrak? V-String? reference electrodes provide the CP monitoring.

SmartPods can be quickly installed with any Work Class ROV system, and instant feedback on current output and potential of protected structures is displayed on the SunStation? readout.

Like all of Deepwater’s innovative CP solutions, the SmartPod is guaranteed to perform.

Main Benefits

Post installed, saves time and money, especially on pipeline installations.

Provides on-board monitoring, no more pipeline surveys or messing with portable CP probes.

Modular design, just figure how many square feet for how many years, then divide to get number of pods required.

Protects many thousands of feet of pipelines, eliminate need for bracelet anodes.

SmartPod allows pipeline coatings to be maintained at maximum efficiency.

pplicationsApplications

Deepwater Subsea Equipment

Infield Flowline Protection

Deepwater Pipeline Protection

Materials

SmartPod uses the highest available quality of sacrificial anode alloys. All steel fabrication uses ASTM A 36 material and is performed in Deepwater's own manufacturing facilities.

SunStation?

The Sunstation monitor is a self-contained CP monitoring terminal powered strictly by the light from an ROV. This eliminates the use of batteries, making SunStation ideal for deepwater applications. Solar panels and LED’s are housed separay in either Delrin for use in < 300 m or Stainless Steel for use in < 3000 m.

RetroClamp? Tie Back

Each SmartPod is shipped with one or more RetroClamps. Typical cables are 2 x 25 feet #4/0 AWG heavy-duty flex cables. Thousands of these clamps are now in service around the world, and many have been installed by ROV. The installation efficiency of the RetroClamp has cut installation costs and allowed for tie-back to any pipe or tubular.

陰極保護(hù)脈沖整流器

產(chǎn)品描述:

Pulse Rectifier Description


The Model 2015 Pulse Rectifier (Pulser) is an air-cooled DC power supply that is designed to work as any conventional rectifier with the added benefit of increased current distribution and reduced cathodic interference on adjacent buried structures. The major components consist of the pulse module, power transformer and control/monitoring panel.

Pulse Module: The pulse power module is the main component of the Pulser. The module consists of the power conversion circuitry that converts the AC to high voltage DC output pulses. It also contains the control, monitoring and communication circuitry. All solid-state power components are mounted on a massive aluminum heat sink. The main circuit board and associated components are also mounted to the heat sink and are protected by a steel housing. The output of the rectifier is electronically controlled to maintain a “constant current" during operation.

Main Power Transformer: The main power transformer is a single phase, toroidal isolation transformer. Toroidal transformers offer improved power efficiency, are lighter weight and are more compact than conventional laminated core power transformers.

Control/Monitoring Panel: This main panel controls and monitors the operational status of the system and contains the following components:

An output control dial (10-turn potentiometer) provides the means for adjusting the pulse output current.

A single, continuous reading ammeter displays system current output. Panel-mounted jacks are provided for cross checking meter accuracy.

The pulse train interrupt switch is available to interrupt the pulse output without switching off the main rectifier power.

Primary and secondary circuit breakers.

System status indicating lights.

Recessed potentiometers are included to adjust pulse width and frequency to improve performance on a site-specific basis.

Enclosures: A number of different enclosure types are available including an industry standard rectifier type cabinet as well as other commercially available decorative cabinets. With a compact physical dimension of 12" x 12" x 16", the 2015 Pulser can even be located in existing, customer supplied cabinets. The standard rectifier type enclosure is manufactured from 11-gauge cold rolled steel with a thermally fused, multistage coating, white in color.

AC Input Section: The standard available AC input configuration is 115/230 volt, single phase. Customer specified AC inputs are also available as a special order.

Removable Safety Panel: This removable panel shields the high voltage pulse output lugs, the AC secondary interconnect, and access to interrupter connection lugs. These lugs allow for the use of a portable interrupter. It is important to note that a portable interrupter only interrupts a low voltage, low current signal rather than the pulse output. This allows the use of virtually all types of commercially available, portable current interrupters.

Serviceability Features

On the standard rectifier type enclosure, front and side opening doors are provided for easy installation and servicing.
   The entire rectifier assembly is built on a slide-out chassis allowing easy removal from the cabinet for service.
   The major electronic components are enclosed in a single module housing.
   A pulse interrupt circuit is provided which will function with any portable current interrupter.
  

Temperature monitoring devices are built into the system. These devices monitor critical electronic component operating temperatures. If the operating temperature should exceed a maximum range, the pulse module output will be interrupted until the temperature reduces to a safe operating level. At that time, the system will automatically restart and return to previous operating parameters.
   For structures that require in excess of 15 amps of protective current, additional rectifiers can be added to the same structure and operated in parallel to provide the required current.
   For multiple structures at a common location, additional rectifiers may be installed on a common anode ground bed. Each rectifier will provide an independently controlled, constant current to each structure.

Model 2015 "Pulser" pulse module

Theory of Operation

The Pulser produces very short duration, very high voltage, direct current electrical pulses for cathodically protecting buried metallic structures, such as pipelines and well casings, from external corrosion.

Pipelines, well casings, and other steel structures buried in soil, corrode. Cathodic Protection has been used to mitigate corrosion for many years. Sufficient direct electrical current (DC) is caused to flow from the soil to the surface of the structure. Typically, the negative lead from a DC rectifier is connected to the structure to be protected, and the positive lead to an anode bed. The ground bed usually consists of one or more rods, called anodes, fabricated from expendable materials such as graphite or silicon steel. The anodes are buried in deep wells, or shallow holes or trenches, in the vicinity of the structure to be protected. The process is called Cathodic Protection, because protective cathodic reactions are caused to take place on the surface of the structure being protected.

The DC current mitigates corrosion by electrochemically reducing any corrosive oxygen molecules and hydrogen ions that may be adsorbed on the surface of the structure in contact with the soil. As additional molecules and ions diffuse from the soil and become adsorbed onto the steel surface, they are also reduced by the continuously flowing direct current. There are certain drawbacks to conventional cathodic protection, however. Current flows in the ground continuously in a relatively large three-dimensional envelope. If there are other foreign metallic structures buried in the soil within the current envelope, damage in terms of metal loss will very likely occur to the foreign structures. Also, the "throw", or distance down the pipeline or well casing, that can be protected, is limited by the magnitude of the current reaching the more distant corroding surfaces.

The corrosive oxygen molecules and hydrogen ions, adsorbed on the surface of the buried structure, are electrochemically reduced within microseconds after the application of cathodic current. Before the corrosion reactions can begin again, additional molecules and ions must diffuse to the surface of the structure from the surrounding soil and become adsorbed. The destructive diffusion and adsorption processes are orders of magnitude slower than the protective reduction process, particularly when the ions are not being driven by a continuously applied cathodic protection voltage.

With Pulse Cathodic Protection the corrosive molecules and ions are electrochemically reduced with very short duration but very high current pulses. Since throw is a function of current magnitude, the very high pulsed currents result in greatly improved throw down the length of the structure. Because of the natural electrical characteristics of the structure/anode system, the greatly improved high current throw is further enhanced by the inductive and capacitive redistribution of that current.

Also, the very short duration pulses are separated by relatively long "off" intervals. The pulse voltage is applied for less than 20% of the total time. Thus, the continuous current envelope and the resulting interference on foreign structures is greatly reduced.

Product Overview

The VSE (Vaulted Seawater Envelope) anode is designed to provide reliable long-term cathodic protection in shallow water locations where the anode system must be buried below natural bottom.

The anode design maintains the MMO activated element in a silt-free seawater envelope, and current is discharged from the anode footprint. This allows optimization of current rating versus dimension, thus minimizing installation cost, and increasing reliability.

The anode structure is engineered to self-bury, and the ultra rugged construction will withstand suction dredging or bottom trawl operations. This makes the VSE ideal for retrofit, as well as for new construction, when shallow water structures are at stake.

Designed for the offshore wind energy operators, VSE offers an elegant green impressed current solution, utilizing renewable energy.

Applications

Offshore wind-turbines

Shallow water offshore / inshore structures

Docks, wharves, piers and jetties

Offshore pipelines

Outfalls and other inshore structures

交流定位筆

產(chǎn)品描述:

Description

The Santronics AC Sensor, Part # 3115, is the first and only UL listed AC voltage sensor to be manufactured * in the U.S.A. The AC Sensor is a hand-held device for determining the presence or absence of 50-600 volts AC in insulated wires, wall receptacles, fuses, junction boxes, switches, and other voltage carrying electrical systems. The AC Sensor determines defective grounds, reverse polarity, and induced voltage.

It is not necessary to disconnect the system in question because no contact is required for operation, and current flow is not necessary to locate voltage. Simply touch the plastic tip to a connection point or move it along an insulated wire. If AC voltage is present, the LED light in the tip will glow cherry red.

There is no ON/OFF switch, since switches can malfunction over time. As a result, the AC Sensor is always on and ready to use.

Benefits

Visual alert to locate voltages of 50-600V AC.

No electrical contact required.

Only uses two AAA 1.5V alkaline batteries (included).

No on/off switch - always ready to use.

Specifications

Description, Non-contact AC voltage sensor

Operating range, 50-600V AC

Barrel & cap composition, Injection molded hi-impact nonflammable ABS with 2200V dielectric at 60 Hz.

Tip composition, Injection molded PVC

Batteries, Two AAA alkaline cells

Operating temperature, -40oC to +55oC

Circuit board, Surface mounted components on FR substrate

Light source, High intensity LED

Weight, 40.6 grams with batteries

Dimensions, 5.75" long x 0.75" diameter

Breakdown voltage, > 4,000V ac

Interior conductor, Brass strip approximay 4.75" long

Operating Instructions

Always hold unit by its body. Keep fingers away from the tip. Remove the end cap to replace batteries.

Simply touch the plastic tip to a connection point or move it along an insulated wire. If AC voltage is present, the tip glow red. The tip will emit a steady glow in the presence of AC line voltage. It will flicker in the presence of static electricity.

Caution 1. Prior to each use, as a safely practice, always test the instrument on a known live circuit to verify proper operation. Treat your AC Sensor with care as you would any other test instrument. Clean Ultimate AC Sensor with damp cloth.

Caution 2. In testing indoor insulated cable where the fibrous filler becomes saturated with water, which is conductive, an electrical connection is formed between the filler and the ground circuit. The length of cable that has become wet is essentially shielded. If a voltage is present on a conductor in this cable, the electric field normally radiated by the voltage will be attenuated by this shielding, and the AC Sensor may not glow even though a voltage is present.

Always approach wet indoor insulated cable with utmost caution. NOT FOLLOWING THESE CAUTIONS MAY RESULT IN BODILY HARM. Cable of this type is specified for indoor use only. It will be subjected to immersion in water only in rare conditions such as flooding.

Defective Grounds: Electrical equipment that has a metal enclosure and is improperly grounded or has a detective ground will always result in the Sensor's tip emitting a steady red glow.

產(chǎn)品描述:

Overview

The ERITECH? EST401 is a hand-held, clamp-on Ground Resistance Tester which measures ground rod and small grid resistance in any season without the use of auxiliary ground rods. The clamp-on ground resistance tester from ERICO? can be used in multi-grounded systems without disconnecting the ground under test. By performing measurements on intact ground systems, the user can measure the resistance to ground and verify the quality of the grounding connections and bonds. Resistance and continuity of grounding loops around pads and buildings may also be measured with the tester.

The ERITECH EST401 includes a current measurement function. The probe’s high sensitivity enables measurement of current leakage flowing to ground or circulating in ground loops down to 1mA and neutral currents to 30Arms. This feature provides additional information that is becoming vital as distribution ground networks carry higher levels of noise and harmonics, which affect power quality.

The ERITECH EST401 has a rugged Lexan? body for durability. A double-walled Lexan shell (or equivalent polycarbonate) encases the probe heads for extra strength. Overall construction and mechanical design ratings such as drop test, weatherproofing against water projections, shock and vibration meet or exceed IEC (International Electrotechnical Commission) standards. The product has been designed to meet IEC 1010.

Battery life information is given at power-up and Auto-Off for power management. Additional features such as resistance and current measurement are displayed on the large LCD.

The ERITECH EST401 is ideal for measuring ground current and ground resistance at pole ground rods, service entrances, pad-mounted transformers, transmission towers, service panels, phone pedestals and central office locations. Extended distances between installations such as high-tension towers will not adversely affect the measurement results.

水具有存儲(chǔ)和交流信息的能力,能和與它接觸的某些材料產(chǎn)生反應(yīng)。例如水(H2O),與鐵(Fe)接觸時(shí),會(huì)發(fā)生化學(xué)反應(yīng):Fe3O2(鐵氧化物/銹)。水有高度的腐蝕性,可能攜帶有一定的“懸浮"物質(zhì),例如鈣,是生成水垢的主要原因。與這些物質(zhì)相關(guān)的原子不斷的在亞原子級(jí)運(yùn)動(dòng)(振蕩)。在亞原子水平上處于不斷振動(dòng)/振蕩的狀態(tài),這種現(xiàn)象稱為布朗分子振蕩。福佩格技術(shù)的核心就是針對(duì)水中的這些物質(zhì)開(kāi)發(fā)出能夠改變其物理特征的振波,通過(guò)量子環(huán)向管道傳遞持久的已被編程的振蕩。振動(dòng)模式是通過(guò)的激光技術(shù)將其 “烙印"或“編碼"在福佩格環(huán)上的。當(dāng)水流通過(guò)安裝了福佩格環(huán)的管道,管道由環(huán)產(chǎn)生“預(yù)編程"的振蕩(影響振蕩)。在水中,當(dāng)影響振蕩遇到自然振蕩,例如鐵銹水垢等相關(guān)的物質(zhì),影響振蕩會(huì)作用并破壞這些物質(zhì)自身的振蕩而使其特性改變。這并不是自然發(fā)生的,鐵與氧不再以三氧化二鐵(鐵銹)的形式結(jié)合,鈣也不再像通常那樣極易析出結(jié)晶生成水垢,而是保持“軟"的溶解狀態(tài)通過(guò)該管道,并可以被水流沖刷掉,同時(shí),對(duì)管道不會(huì)造成任何傷害。福佩格量子管通環(huán)是一個(gè)用于存儲(chǔ)和釋放 “已被編程的振蕩" 的載體或遞送途徑。它能夠長(zhǎng)時(shí)間的存儲(chǔ)并保留必要的“影響振蕩",并*以恒定速率釋放。福佩格對(duì)各種物質(zhì)進(jìn)行了擴(kuò)展測(cè)試,以確定福佩格環(huán)的*材料。zui終,發(fā)現(xiàn)具有高含量硅的鋁合金zui符合這一標(biāo)準(zhǔn)。環(huán)境溫度的變化會(huì)引起材料(如鋁)的膨脹和收縮,這種膨脹或收縮的運(yùn)動(dòng)產(chǎn)生能量,能源為圓環(huán)提供了動(dòng)力。環(huán)境溫度的波動(dòng)提供了足夠的能量以創(chuàng)造不斷釋放的脈沖,這些脈沖通過(guò)管壁輸入到管道中的水流中。

福佩格環(huán)可在-273℃到+ 500℃的溫度下工作,*的操作環(huán)境為0℃到150℃。

深水資源CP系統(tǒng)

產(chǎn)品描述:


Product Overview

The SmartPod system is an inligent version of Deepwater's well-proven RetroPod? cathodic protection system for offshore platforms. The system greatly simplifies deep water cathodic protection by providing a modular anode structure with on-board status-monitoring, using Deepwater's patented SunStation? cathodic protection monitor technology (each unit contains 3 SunStation monitors).

Each SmartPod can protect a number of discrete subsea structures and can be configured to provide 20 years of cathodic protection to over 25,000 square feet of coated steel.

RetroClamps allow an ROV to connect to the subsea structures, and Polatrak? V-String? reference electrodes provide the CP monitoring.

SmartPods can be quickly installed with any Work Class ROV system, and instant feedback on current output and potential of protected structures is displayed on the SunStation? readout.

Like all of Deepwater’s innovative CP solutions, the SmartPod is guaranteed to perform.

Main Benefits

Post installed, saves time and money, especially on pipeline installations.

Provides on-board monitoring, no more pipeline surveys or messing with portable CP probes.

Modular design, just figure how many square feet for how many years, then divide to get number of pods required.

Protects many thousands of feet of pipelines, eliminate need for bracelet anodes.

SmartPod allows pipeline coatings to be maintained at maximum efficiency.

pplicationsApplications

Deepwater Subsea Equipment

Infield Flowline Protection

Deepwater Pipeline Protection

Materials

SmartPod uses the highest available quality of sacrificial anode alloys. All steel fabrication uses ASTM A 36 material and is performed in Deepwater's own manufacturing facilities.

SunStation?

The Sunstation monitor is a self-contained CP monitoring terminal powered strictly by the light from an ROV. This eliminates the use of batteries, making SunStation ideal for deepwater applications. Solar panels and LED’s are housed separay in either Delrin for use in < 300 m or Stainless Steel for use in < 3000 m.

RetroClamp? Tie Back

Each SmartPod is shipped with one or more RetroClamps. Typical cables are 2 x 25 feet #4/0 AWG heavy-duty flex cables. Thousands of these clamps are now in service around the world, and many have been installed by ROV. The installation efficiency of the RetroClamp has cut installation costs and allowed for tie-back to any pipe or tubular.


A concrete mattress at the base provides ballast for stability. CP monitoring is provided by a SunStation monitor with 3 readouts.

Product Overview

RetroBuoy is the state-of-the-art impressed current technology for offshore structures. The modular sled based system couples design flexibility with ease of installation using diver or ROV support. With a proven track record of success, the RetroBuoy system redefines impressed current retrofit technology, saving hundreds of thousands of dollars in CP retrofit costs on even modest retrofit programs.

The RetroBuoy system cuts retrofit costs by delivering more cathodic protection, more efficiently with each installed sled. One typical RetroBuoy sled can deliver up to 400 Amps of corrosion protection – enough to protect 80,000 square feet of steel. The conventional alternative protection would need 32 US tons of sacrificial aluminum.

Applications

Offshore platform jacket retrofit.

Very effective on multi-jacket complexes, capable of protecting multiple structures.

Spread-moored FPSOs.

Large dock structures.

Main Benefits

The lowest installed cost in the industry. Installation cost drives offshore CP retrofit budgets: install a single RetroBuoy sled or 48 pairs of sacrificial anodes weighing 500kg each.

Being a remote system, current distribution is optimized, and potential levels are maintained within a tight range over the whole structure.

Exhaustive attention has been given to every design detail; RetroBuoy is modular and redundantly designed.

The design allows the system to be quickly customized to provide sled current capacities from 250-500 Amperes for 15-25 year design life. It also allows us to provide prompt delivery – typically 4-6 weeks from order.
