Research On Energy Saving Wire Selection Of 66kV Transmission Line In Fushun

Lead is one of the most basic components of transmission line element, wiring project investment accounted for ontology engineering investment by about 30%, the whole overhead transmission line tower, foundation, insulators and fittings strength,economic and technical indicators plays a decisive influence.In our country, the wire of overhead transmission line is mainly made of steel, and the application history of this kind of wire is over 100 years. With the progress of the society, the China State Grid Corp put forward the requirements of building environment friendly and resource conserving society, and promote the application of new technology and new materials in engineering construction.In recent years, with the development of the company's "green power grid" awareness, and actively promote the application of new technology has become a key part of the company's scientific and technological innovation.The energy saving principle and performance of the high conductivity steel core aluminum stranded wire and aluminum alloy wire are introduced. The energy saving principle and performance of the high conductivity steel core aluminum alloy wire and aluminum alloy wire are introduced. The paper analyzes the 3 kinds of energy saving wires in electrical and mechanical characteristics. The paper analyzes the economic performance of the wire.To put more new technologies, new materials, new technology applied to the power grid construction, according to the national grid company infrastructure technology, 21,2014, on carrying out the 2014 steel core high conductivity aluminum wire and other promotion application work notice requirement, the Fushun 66 kV power line as a pilot project of energy saving. This paper focuses on the engineering practice, mainly from the energy-saving lead structure and type selection, energy saving wire electrical performance comparison, energy saving wire mechanical characteristics, line cost analysis, annual cost calculation and other aspects of the ordinary steel core aluminum stranded wire and three kinds of energy saving wire(i.e. high conductivity steel core aluminum and aluminum alloy), combined with the terrain and climate in Fushun, and the other factors, such as the selection of energy-saving conductor.
