Usage:

The cable is suited to linking of solar panels, inverters and for photovoltaic systems.

They are resistant to negative impacts of UV radiation, ozone and mainly to temperature effects of outdoor environment.

They are resistant to hydrolysis, ammoniacs, biogasses and to chemical substances.

The cables are intended for power distributions at rated voltage of 0,6/1,5 kV in the environment according to ČSN 33 2000-3 in the cathegory AN1 and AN2 (UV stability). The cables can be used in an environment with a fire danger and it is possible to install them on a flammable surface. Other usage has to be negotiated with the cable producer.

Plastic materials used for cable production are tested against effects of petroleum products of groups IRM 902 and IRM 903.
