A breakthrough has been made within the analysis and improvement of a brand new sort of UHV AC composite cross arm

Recently, after more than three months of hard work, the China Electric Power Research Institute has completed the electrical assessment test of the new UHV AC composite cross arm insulator, and a breakthrough has been made in the research and development of the UHV AC new composite cross arm.

 

The composite cross arm has the advantages of good anti-fouling performance, lightweight, and convenient installation. When applied to UHV poles and towers, it can produce good economic and social benefits. To support the development of a composite cross arm for the poles and towers of the State Grid Corporation’s 1000 kV Ximeng-Shengli UHV AC transmission project, the project team went deep along the project to investigate the operating environment and the external insulation configuration of adjacent lines.
