TUV EN50618 and IEC62930 CABLE

4. TUV EN50618 Photovoltaic Cable is used for connecting cables of photovoltaic power generation system, such as parallel cables between DC distribution box and DC distribution box, series cables between DC photovoltaic modules and components, cross-linked cables between DC distribution box and DC distribution box, and cables between DC distribution box and inverter. It is also suitable for AC application cables between inverters and transmission networks. Photovoltaic cable adopts twisted annealed tinned soft copper wire, conductor operating temperature is 120℃. The bending radius of the cable should be greater than 6 times the outer diameter of the cable. This product is a green halogen-free product, in the event of a fire accident, there are two important requirements for long-term exposure of toxic and harmful gases to the outdoors: 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, photovoltaic cable insulation sheath is crosslinked polyolefin material, ordinary cable will crack in outdoor use for a few years, photovoltaic cable service life of up to 70 years.
