Led by its smart grid research institute of state grid corporation of science and technology project advanced composite conductor practical key technology research through the acceptance.Project results improve the safety and reliability of the wire and economic practicability, promote the large-scale application of the conductor in the power grid transmission line.

The project, started in 2012, led by its intelligence institute, joint its electric power co., LTD., hebei, liaoning province north electric power research institute and other units to research and development.Main conductor composite toughening technology, study on aging technology and low cost.After three years of efforts, the project team by molecular structure design and structure design of high toughness of composite core, developed the high toughness of composite conductor, and in the south of henan zhoukou 110 kv line, south wood line for the engineering application;Project team by high strength glass fiber doping technology and low cost of the plug structure design, developed with certain cost advantages of high strength glass fiber/carbon fiber composite conductor, and in liaoning dandong 220 kv wide chicken wire for the engineering application.The team also verified the carbon fiber composite conductor in extreme conditions (dancing and heavy ice) under the condition of applicability, safety developed rapid aging assessment method.Project results in mixed resin toughening, fiber wire core material preparation has reached the international leading level.
