Description

technical field [0001] The invention belongs to the field of high-voltage wires, and relates to a wire material and a preparation method thereof, in particular to a composite high-voltage wire material and a preparation method thereof. Background technique [0002] In power transmission, the power loss is mainly in the resistance. At the same time, during high-voltage power transmission, the overhead conductor is the main component of the overhead power line, and its function is to transmit current and transmit electric power. Since it is erected on the pole tower, the wire must bear its own weight and external loads such as wind, snow, ice, etc., and will also be eroded by the chemical substances contained in the surrounding air. Therefore, not only are the wires required to have good electrical properties, sufficient mechanical strength and corrosion resistance, but they are also required to be as lightweight and cheap as possible. The materials of overhead conductors in...
