Research on the Reconstruction Design of Ground Wire Fittings on Transmission Line about Three-span

Abstract

State Grid related standardized design atlas are not satisfied with the current “three-span” requirements, previous literatures were only analyse the “three-span” fitting strings of the transmission line from the aspect of the natural environment and the material of the fittings. In order to ensure the safe and reliable operation of transmission line span high-speed railways, expressways and important high-voltage transmission lines, this paper demonstrates the essential safety of the fittings of the ground wire on the transmission line, and proposes the actual string type to improve the safety redundant.
