2 – UV resistant polyolefin insulation.

TOXFREE® ZH OUTDOOR H07Z1-K (AS) Cu/Sn, A WIRING CABLE SUITABLE FOR OUTDOOR INSTALLATIONS
Cables for photovoltaic installations need to have specific characteristics to be able to withstand inclement weather and extreme temperatures without affecting their performance at any time. Thus, the TOXFREE® ZH OUTDOOR H07Z1-K (AS) Cu/Sn cable is highly resistant to degradation caused by ultraviolet rays (UV), according to the EN 50618 standard, and also to the effects of corrosion.
It is a halogen-free cable which, among its features, also stands out for its capacity to avoid galvanic couple when connecting metals of different potential. Thus, it is possible to avoid a significant effect on the metal with the greatest negative potential, oxidation. In addition to the direct effect on the cable, eliminating this problem extends the time of full performance of the photovoltaic installation.
MAXIMUM CPR CERTIFICATION
TOXFREE® ZH OUTDOOR H07Z1-K (AS) Cu/Sn cable also offers the highest fire safety. It has the highest CPR (Construction Products Regulation) certificate, B2ca-s1a,d1,a1, preventing the spread of fire in case of fire.
High temperatures are a very threatening factor for the maintenance of photovoltaic panels. There are many cases of solar panel fires caused by the deterioration of the installation. In these cases, if a cable without adequate CPR performance has been used, the fire can spread rapidly, damaging the entire installation. With a cable such as TOXFREE® ZH OUTDOOR H07Z1-K this risk is completely avoided thanks to its fire characteristics.
