On August 22, 2020, the development of solar energy in recent years showed a blowout development two thousand and ten By the end of the year, the installed capacity of solar photovoltaic power generation in China had reached 893 MW , ranking first in the world seven Expected two thousand and twenty In, the total installed capacity of solar photovoltaic power generation in China will exceed 30000MW The state also supports photovoltaic construction projects. PV power generation has driven related products, such as PV cable The rapid development of.

Usually, the low-voltage DC power generated by photovoltaic power generation needs to be converted into AC power. The connecting cable between photovoltaic cells and AC/DC inverters is photovoltaic cable. Theoretically, a photovoltaic module generally needs two root 0. 8-1m Single core cable between Piece development speed, to two thousand and twenty The consumption of photovoltaic cables in China will reach fifteen ten thousand km The demand space is large.

The abbreviation of photovoltaic cable is PV The cable has a simple structure, namely conductor, insulation and sheath. At present, there is no national standard for photovoltaic cables in China. The most authoritative certification of photovoltaic cables in the world is TUV Rhine TUVMARK And UL Certification, main reference standards 2Pfg1169 or UL 4703 The samples will be sent to Germany or the United States, so the certification cycle is long, the cost is high, and the design focus of each sample is different.

The performance requirements of general photovoltaic cables are as follows : Thermal life of cable insulation and sheath one hundred and twenty Not less than at ° C twenty-five In, the cable passed the dynamic penetration test, the cable passed the single vertical combustion test, and the cable passed the -4O ℃ low temperature test, the cable passes the acid alkali test, damp heat test, ozone test and weather resistance test. However, the application environment of photovoltaic coil is different, so the laying place should be considered in timing, such as preventing mice and other small animals from biting.
