Abstract

The invention provides a high-intensity clearance type super heat-resistant aluminum alloy conducting wire, which relates to the power transmission and distribution equipment and includes a steel core stranded by high-intensity steel wires and a super heat-resistant aluminum ally solid wire stranded and wrapped at the periphery of the steel core. The surface of the steel core is enwound and wrapped by bowline, the aluminum solid wire is stranded and wrapped on the external surface of the bowline; a clearance is arranged between the steel core and the bowline, which is filled with anticorrosive and heat-resistant ointment. The equipment has the beneficial effect that the transmission capacity is enhanced, the intensity conservation rate is kept to be more than 90%, the service life is prolonged remarkably and the intensity is high because of the adoption of the special high-intensity galvanized wire; the inner layer conductor of the wire adopts bow-type structure, which can effectivelycontain the anticorrosive and heat-resistant ointment and has remarkable effect on reducing sag.

Description

technical field [0001] The invention relates to a power transmission and transformation equipment, in particular to a high-strength wire used on an overhead power transmission and transformation line. Background technique [0002] The conductors used in the existing overhead power transmission and transformation lines are all ordinary galvanized steel wires and ordinary aluminum alloy single wires twisted together; the transmission capacity of this ordinary steel-cored aluminum conductor is small, the long-term working temperature is only 70 °C, and the linear expansion coefficient Big, big sag. With the continuous development of the construction industry and the increasing demand for electricity, how to solve the bottleneck of power transmission and provide abundant power resources for the construction industry has become a key issue that needs to be solved urgently. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages ...
