With the increase in the construction of solar photovoltaic power generation system facilities, the use of cables is also increasing. All cables used in photovoltaic systems must be halogen-free special cables, which are flame-retardant, fire-resistant, non-toxic, and resistant to sunlight aging. This will greatly promote the development of environmentally friendly cables for solar photovoltaic systems.
Traditional flame-retardant PVC sheathed cables are mainly used for power distribution lines, and the laying environment is mainly in the air or soil, with few additional properties. If it is used in the harsh environment where photovoltaic systems are deployed, because the materials used contain halogen polymers and a large amount of halogen flame retardants, as long as the cable is in contact with the flame, a large amount of harmful corrosive halogen acid gas and dense smoke will be generated when the cable is burned. It also corrodes equipment and equipment, causing "secondary disasters." There are more and more solar photovoltaic facilities in China. The cables used in photovoltaic systems should not produce harmful corrosive halogen acid gas when burning, and should be moisture-proof, waterproof, acid and alkali resistant, and light aging resistant. Therefore, the technical content of photovoltaic system cables will increase. Come higher.
