The Design About 110kV BiTong Transmission Line Reconstruction Project

With the rapid social development of Guangzhou,escalating economic structure and improving people’s living standards, all levels of society’s growing demand for more electricity. Power load gradually increased demands more continuity and reliability of electricity supply. To meet the rapid economic development of Conghua Guangzhou, to further improve the power supply capacity and reliability, Guangzhou Power Supply Bureau recently ratchets up efforts in building electricity infrastructure and carrys out a large number of 110 kV transmission line design.In this paper, according the relevant data of Guangzhou Conghua’s transmission lines design, in accordance with the requirements of the power line operation and maintenance, the actual demand load, terrain feature, combined with professional knowledge of transmission line design, strict implementation of DL / T 5092-1999 <110 ~ 500 kV overhead transmission line design technical regulations>,etc., completed the design of a part of transmission line reconstruction project.The paper includes the selection of overhead lines, line fittings, tower, overhead lines mechanical calculations and production of stress on cables sag curve, production installation curve, positioning tower, tower based design, vibration-proof and lighting-proof design.
