May 30, 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. The following section will introduce several major new energy cable product categories and performance, domestic and foreign application standards, development prospects, etc.
As a clean and renewable energy, wind power cable is also the most large-scale, technologically mature and commercially promising power generation mode among many new energy sources. According to public data, the available wind energy resources in China's mainland and near coast have reached nearly 1 billion kW. According to China's Medium and Long Term Development Plan for Renewable Energy, the total installed capacity of wind power in China will reach 30 million kW in 2020, and 2013-2020 is still a golden period of great promise. Wind power generation cables include control cables, signal cables and torsion resistant cables in the wind turbine room and tower power cable Due to the harsh environment of the wind farm and the twisting of the power cable with the swinging of the impeller, the cable for wind power generation is generally required to be high, such as low temperature resistance, oil resistance, torsion resistance, weather resistance, UV resistance, acid and alkali resistance. At present, there is no national standard for wind power cables in China, There are only industrial standards such as TICW01-2009 Twist resistant Flexible Wires for Wind Power Generation with Rated Voltages of 1.8/3kV and Below issued by the National Wire and Cable Quality Supervision and Testing Center.
Tower cable is the most widely used cable in wind power generation system, and we often refer to wind power cable as such. 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.
In recent years, the development of photovoltaic cable solar energy has shown a blowout development. By the end of 2010, the installed capacity of solar photovoltaic power generation in China had reached 893 MW, ranking seventh in the world. It is estimated that the total installed capacity of solar photovoltaic 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 cable between 8-1 and 8-1, 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 English abbreviation of PV cable is PV cable, which 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, mainly referring to the standard 2 Pfg 1169 or UL 4703, and the samples are to be sent to Germany or the United States, so the certification cycle is long, the cost is high, and the design focus of various products is different.
