Abstract

The invention discloses an aluminum-based carbon fiber composite core wire comprising a core and an aluminum alloy conductor sleeving the core. The aluminum alloy conductor is stranded around the core which is made of aluminum-based carbon fiber composite. Copper layer is arranged on the outer surface of the core and covered with a pyrolytic carbon layer. The aluminum alloy conductor covers the pyrolytic carbon layer. The aluminum-based carbon fiber composite core wire comprises, by volume percent, 2-5% of the carbon fiber, 1.2-1.5% of the copper layer, 1-10% of the pyrolytic carbon layer and the rest of industrial virgin aluminum. The aluminum-based carbon fiber composite core wire has the advantages that the bamboo joint problem is avoided, conductivity is high, bending strength and extension strength are strong, and better high-temperature and heat resistance is achieved.

Description

technical field [0001] The invention relates to a wire for an overhead transmission line, in particular to an aluminum-based carbon fiber composite core wire, which belongs to the field of overhead wire manufacturing. Background technique [0002] As the carrier of power transmission, overhead transmission wire occupies an extremely important position in the transmission line. For a long time, steel-cored aluminum stranded wires have been mainly used for overhead conductors. In recent years, my country's industrial and agricultural production has developed rapidly, and the power lines in some areas have not kept up with the needs of development and are in urgent need of renovation. However, based on the constraints of investment costs and investment time, how to use effective corridor resources to increase transmission capacity has become a key issue in power construction. A big subject. For the general methods of increasing the voltage level, transforming the line or usin...
