Description

technical field

[0001] The invention relates to the technical field of cables, in particular to a preparation method of a graphene rare earth aluminum alloy high-conductivity material cable. Background technique

[0002] With the rapid development of my country's national economy and the continuous improvement of people's living standards, the electric power industry has become a basic industry and public utility that supports the development of the national economy and society, and people's dependence on electricity is also increasing. With the continuous increase of my country's power coverage, the demand for wires and cables as the carrier of power transmission is also increasing. Copper is used as the core. Because copper is expensive and dense, the cores used in wires and cables can be made of aluminum. Instead of copper, at present, the wire core made of ordinary aluminum has poor electrical conductivity and heat resistance, and disconnection often occurs during the pro...
