scope:

These requirements apply to single-core cross-linked insulated power cables with cross-linked sheath. These cables are for use at the direct current (d.c.) side of photovoltaic systems, with a rated d.c. voltage up to 1,5 kV between conductors and between conductor and earth. This standard includes halogen free low smoke cables and cables that may contain halogens. The cables are suitable to be used with Class II equipment as defined in IEC 61140. The cables are designed to operate at a normal continuous maximum conductor temperature of 90 °C. The permissible period of use at a maximum conductor temperature of 120 °C is limited to 20 000 hours. NOTE - The expected period of use under normal usage conditions as specified in this standard is at least 25 years. Multi-core constructions are allowed provided that all cores are individually sheathed and comply with all requirements set in this standard. Any additional elements shall comply with all material requirements set in this standard.
