Solar cables for photovoltaic systems
Photovoltaic Solar Cable H1Z2Z2-K
Description
Cables are designed for use in photovoltaic power supply systems: indoor and/or outdoor.
The special insulation has qualities of high abrasion resistance to high temperature.
Special insulation has property of flame retardant and ozone resistance.
Cables are resistant to climatic influences, UV radiation, oils and chemicals.
