Research And Application Of UHVAC Transmission Tower Construction Process

As the main component of UHV transmission lines,the UHV transmission tower isa supporting structure which deliveres the powerful electric energy to center of load,andis an important part of ensuring technical conditions of the electrical circuit. Since theUHV Tower big structure size, cross arm length, components, made for high voltagetransmission line tower is very difficult. And below750kV transmission line projectgroup of tower construction technology and group of tower main tool can not meet theneeds of the UHV transmission line tower construction. So we need the characteristics ofUHV AC transmission lines, the research for the tower erection method, and it wasapplied in practical engineering.In this paper, on the basis of the existing methods, aiming at a1000kV UHV ACtransmission part of the tower, the tower construction method for large cross-sectiontower were studied respectively, determine the pole selection and calculation process,through the simulation proposes a set of economic security and stability of the processdesign and construction method, to solve the special terrain group tower method and partof the tower type group tower process on the problems of the project, improve the grouptower construction technology level and efficiency of construction, reduce theconstruction difficulty mountainous area, reduce the construction risk.
