High Quality PV1-F tinned Copper 2.5mm 4mm 6mm PV Cable For Photovoltaic Solar Cable
Product Introduction
1. Photovoltaic cable:
It is designed according to the special environmental conditions where the photovoltaic power generation equipment is located. It is used for the DC voltage terminal, the outgoing link of the power generation equipment and the confluence connection between the components. It is suitable for areas with large temperature difference between day and night, salt fog and strong radiation.
Features: Low smoke and halogen free, excellent cold resistance, UV resistance, ozone resistance and weather resistance, flame retardant, cut mark resistance, penetration resistance.
Ambient temperature: -40℃～+90℃; Maximum conductor temperature: 120℃ (allowable short-circuit temperature of 200℃ within 5s);
Rated voltage: AC0.6/1KV; DC1.8KV
Design life: 25 years

The cross-sectional area of the DC cable is determined according to the following principles: the connection cable between the solar cell modules and the modules, the connection cable between the battery and the battery, and the connection cable of the AC load. Generally, the rated current of the selected cable is the maximum continuous working current of each cable. 1.25 times; the connecting cable between the solar cell array and the square array, the connecting cable between the battery (group) and the inverter, the rated current of the cable is generally selected to be 1.5 times the maximum continuous working current in each cable.
