The International Electrotechnical Commission (IEC) has released IEC 62930:2017 Pre-release Version (PRV). This standard applies to Electric cables for photovoltaic systems with a voltage rating of 1,5 kV DC; and is now available on the IEC webstore.
Description: “IEC 62930:2017 applies to single-core cross-linked insulated power cables with cross-linked sheath. These cables are for use at the direct current (DC) side of photovoltaic systems, with a rated DC voltage up to and including 1,5 kV between conductors and between conductor and earth. This document includes halogen free low smoke cables and cables that can 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 20000 h.”
