Problems solved by technology

[0002] At present, most solar photovoltaic cables use ordinary PVC cable materials, and ordinary PVC cable materials contain toxic substances such as halogens, which will emit hydrogen chloride gas when burned, which is easy to pollute the environment, and is not resistant to ozone and water vapor, and has a short life.
Secondly, due to the very harsh environment in which photovoltaic cables are located, not only high temperature, strong ultraviolet radiation, and high ozone content, but the tensile strength and elongation at break of the existing radiation cross-linked halogen-free low-smoke insulating materials for photovoltaic cables The mechanical properties such as rate are poor and cannot meet the required requirements
