Research And Design On Five110kV Circuits On Same Tower

In recent years, along with the city urban electric load increases, the city built220kV transformer substation more and more. How will the substation numerous110kV transmission lines and reliable economic send, the layout can use limited line corridor resources, is the city planning department, power grid construction units and the plication in engineering design problems needed to resolve. By adding a route wire loop number, through the use of carbon fiber composite core conductor increases with each loop of the conveying capacity, can improve and alleviate the route corridor resources shortage. This paper studies the five circuit lines on the same tower110kV line is based on the purpose of research and development. Multi circuit steel pole insulation coordination, lead selection, tower structure calculation selection, on-line monitoring, engineering cost system together, for city planning, power grid on struction and engineering design to provide a complete power supply scheme.In this paper, combining with engineering practice, introduced in Inner Mongolia Power Supply Bureau Hohhot West substation110KV output transmission line project, the five circuit lines on the same tower and its application effect.
