Halogen free, low smoke, flexible, single-core, cross-linked double layers photovoltaic cables, in particular for use at direct current (DC) side of photovoltaic systems. These cables are designed to match with most PV components according to class II with a nominal DC voltage of 1.5 kV (IEC) between conductors and between conductor and earth. The maximum permitted operating DC voltage is 1.8 kV. The cables are in compliance with IEC 62930 and EN 50618. They 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.
