Problems solved by technology

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 production process, which increases its production cost and use cost; using aluminum alloy as the wire core, The structure of the aluminum alloy needs to be improved, the strength, conductivity and plasticity of the aluminum alloy cannot be optimized at the same time, and the flex fatigue resistance of the aluminum alloy is not good, which limits the use of the aluminum alloy core
