EN 50618-2014 光伏系統(tǒng)用電纜


Introduction

This standard specifies cables for use in Photovoltaic (PV) Systems, in particular for installation at the DirectCurrent (d.c.) side. These cables are suitable for permanent outdoor use for many years under variabledemanding climate conditions. Relatively stringent requirements are set for these products in line with theexpected harsh usage conditions

During the writing of this standard the joint work of TC 64 (Electrical installations and protection againstelectric shock) and TC 82 (Solar Photovoltaic Energy Systems) on the design and installation of PV systemshas been taken into account.

Scope

This European Standard applies to low smoke halogen-free, flexible, single-core power cables with crosslinked insulation and sheath. in particular for use at the direct current (d.c.) side of photovoltaic systems, witha nominal d.c. voltage of 1,5 kV between conductors and between conductor and earth.

The cables are suitable to be used with Class ll equipment.

The cables are designed to operate at a normal maximum conductor temperature of 90 °C, but for a maximumof 20 000 hours a max. conductor temperature of 120 'C at a max. ambient temperature of 90 'C is permitted.

NOTE The expected period of use under normal usage conditions as specified in this standard is at least 25 years
