Transmission line composite insulator cross arm
SHEMAR cancels the traditional suspension insulator, and the end is directly connected to the conductor with hanging fittings. The main material is FRP, and the surface is injected with silicone rubber auxiliary shed. In the design of cross arm structure, according to different voltage levels and different working conditions, single column, single column cable-stayed and double column cable-stayed are designed and used respectively. The voltage level covers AC 35kV ~ 1000kV and DC 500kV ± 800kV, widely recognized by customers all over the world.
Improving the safety and reliability of transmission lines：SHEMAR power transmission line composite insulator cross arm uses the excellent insulation performance of composite materials, cancels the suspension insulator, and suspends the conductor at the end of cross arm through the clamp, so as to eliminate the risk of galloping flashover accident caused by wind swing and improve the safety and reliability of the line; the horizontal composite cross arm has good anti fouling and anti-icing performance. At the same time, it makes full use of the excellent hydrophobicity and hydrophobicity migration of SHEMAR composite material, which greatly improves the product's ability to resist pollution flashover, rain flashover and ice flashover.
Reduce the comprehensive cost of the whole life cycle：Without considering the wind swing space of suspension insulator, the transmission line composite insulator cross arm can greatly reduce the corridor width of transmission channel, the height of tower body, the floor area of tower foundation, save tower materials and make the overall cost lower than that of traditional tower. At the same time, the cost of land acquisition for tower foundation and the cost of line corridor demolition are greatly saved. The whole life cycle maintenance free characteristic of SHEMAR composite cross arm also greatly reduces the operation and maintenance cost, and has significant economic benefits.
