On November 23, 2020, New energy cable It will be the development goal of wires and cables. New energy cables can be generally divided into: PV cable , wind power cable, offshore oil platform cable, nuclear power station cable, electric locomotive cable, inland conventional and unconventional natural gas cable, etc. below New energy cable manufacturer This paper introduces the categories and performances of several major new energy cable products, application standards at home and abroad, and development prospects.
PV cable: It is estimated that the total installed capacity of solar PV power generation in China will exceed 30000 MW by 2020. The state also supports photovoltaic construction projects. Photovoltaic power generation has driven the rapid development of related products, such as photovoltaic cables. 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 2 pieces of 0 Single core cables between 8-1m, so if we follow the corresponding development speed of photovoltaic modules, the consumption of photovoltaic cables in China will reach about 150000 km by 2020, with a large demand space.
The performance requirements of general photovoltaic cables are as follows: the thermal life of cable insulation and sheath shall not be less than 25 years under the environment of 120 ℃, the cable shall pass the dynamic penetration test, the cable shall pass the vertical combustion test of a single cable, the cable shall pass the low temperature test of - 40 ℃, and the cable shall pass the acid alkali test, damp heat test, ozone test and weather resistance test. However, the application environment of photovoltaic cable is different, so the laying place should be considered in the design, such as preventing small animals such as rats from biting.
Nuclear grade cable
The construction and choice of nuclear power plants is one of the topics concerned by countries in the 21st century. Whether it is the nuclear crisis in Iran and North Korea, the Fukushima nuclear leak in Japan, or the referendum in some European countries, all of them revolve around the choice of nuclear power. However, regardless of the choice, the number of cables required for each nuclear power plant is huge.
Tower cable: tower cable is the cable used in the wind power generation system, and we often refer to the wind power cable. Because the tower drum cable is constantly swinging forward and backward with the fan, the performance requirements of the tower drum cable are extremely strict, that is, to ensure that the structure is soft, but also require high tensile strength, low temperature resistance (- 40 ℃), ultraviolet resistance, torsion resistance, salt fog resistance (such requirements exist in offshore wind power plants), seawater corrosion resistance, friction resistance, weather aging resistance, flame retardant and other performance.
