Copper Conductor concentric cable 4mm2

Long-term exposure of solar cables to the outdoors has two important requirements: The first is weather resistance, mainly high and low temperature resistance. The temperature of the photovoltaic power generation environment is very high in summer, even up to 90 degrees Celsius, while the temperature in some areas is very low in winter, reaching minus 30 to 40 degrees Celsius. Photovoltaic cables require low temperature resistance of 40 degrees Celsius, high temperature resistance of 125 degrees Celsius, can basically adapt to various extreme weather on the earth. The second is its UV protection. Ultraviolet radiation causes the cable insulation sheath to crack, the solar cable insulation sheath is made of cross-linked polyolefin materials, ordinary cables in outdoor use for a few years will crack, photovoltaic cable service life of more than 25 years. Yonghao TUV solar cable takes these factors into account, to solve these problems in the use of the short board, Yonghao TUV solar…
