UL Solar Cable for Photovoltaic Generating Equipments
1.Application
The control cables for photovoltaic generating system is designed according to the peculiar ambient conditions and requirements, used in the signal and protection control loop.
This series of cable meet with the peculiar requirements of photovoltaic generating plant, suitable for the zone of high temperature, cold, grassland, moisture, salty fog, strong UV radiation, ozone and etc, also in consideration of anti – compact, tensile, animals bite, and use in higti building, etc.
