SOLAR Cables

Solar PV String Cable By Prysmian

Prysmian TECSUN (PV) H1Z2Z2-K solar cables acc. to EN 50618, are intended for use in Photovoltaic Power Supply Systems at nominal voltage rate of 1,5/1,5kV DC. They are suitable for applications indoor and/or outdoor, in industrial and agriculture areas, in/at equipment with protective insulation (Protecting Class II), in explosion hazard areas (PRYSMIAN Internal Testing).

The solar cables can be installed fixed, freely suspended or free movable, in cable trays, conduits, on and in walls. TECSUN(PV) H1Z2Z2-K cables are suitable for direct burial (PRYSMIAN Internal Testing), where the corresponding guidelines for direct burial shall be considered.

Thanks to more than 15 years of positive experience with direct burial, not only according to the internal tests performed, but also to the successful installation in PV plants worldwide, the TECSUN(PV) cables are suitable for direct burial in ground (Prysmian Internal Testing). The corresponding installation guidelines shall be taken in consideration.
