Application of new material composite cross arm in 500 kV double-circuit transmission line

It is reported that to fully promote the application of new technologies in infrastructure construction and build a more intelligent, economical, and environmentally friendly green power grid, China Southern Power Grid Corporation has built the first phase of the Zhanjiang 500kV Datang Leizhou Power Plant into the system project (first tender ) In the trial of the new technology application composite cross-arm pole tower. Compared with ordinary transmission line towers, this technology has the following main features: First, it uses the insulation properties of composite materials to effectively reduce the width of the line corridor and reduces the cost of transmission line construction; Second, it uses the excellent corrosion resistance of composite materials to reduce The degree of corrosion of transmission towers in coastal and heavy industrial areas increases the service life of transmission lines; the third is to use the characteristics of high strength and lightweight of composite material towers to reduce the difficulty of construction and construction of transmission towers and improve the efficiency of power grid construction in mountainous areas.
