On September 11, in Xingcheng Avenue, Wuhan Economic Development District, 43 power supply operators were set up a 10 kV radical line of about 3 kilometers long and overhead lightning moisturizing lines. This distribution network lightning protection line renovation project is an important measure for State Grid Wuhan power supply companies to improve regional power supply reliability. It will provide strong power supply guarantee for the automotive industry of Wuhan Economic Development Zone.

The Wuhan Economic Development Zone is located in the southwest of Wuhan. It is located on the east side of the Jianghan Plain, with a flat and open terrain, and some areas are at the "Thunderbolt Corridor". Due to the randomness and concentration of lightning strikes, lightning harm has become one of the main reasons that affect users' safety and reliable power consumption. In order to enhance the thunder resistance resistance of the power distribution line, the State Grid Wuhan Power Supply Company began to pilot the use of overhead lightning mocking lines in the high -incidence area of ​​lightning strike lines.

According to Zhong Yunjun, the power grid construction class of the power supply company of the State Grid Wuhan Economic Development Zone, although the 10 kV grid -with network overhead insulation guide line has a good insulation performance and can reduce the failure caused by external reasons The metal short -circuit channel eventually causes the wire disconnection. Therefore, for overhead insulating wires, it is still necessary to seek lightning protection to minimize the impact of lightning strike lines.

At present, the company's planned distribution network lightning protection line reconstruction project involves 27 lines of 10 kV lines in the Wuhan Economic Development Zone, covering all the empty and thunder areas of the empty lines outside the yarn area and the dense area of ​​the Yinlian Lake Fish Pond dense area. All support lines will be about 160 kilometers of newly -built airlighted lightning lines. It is expected that after the implementation, it will greatly alleviate the lightning and failure of lightning and faults in the lightning of the lighting in the lightning area of ​​the Wuhan Economic Development Zone.
