As a generator accessory, the conductor wire is indispensable to use, and the normal well-known stability and the cycle service life of the generator are directly influenced by the performance of the conductor wire. Therefore, it is imperative to develop a conductor wire for a generator having excellent overall performance.

The method has short flow and high efficiency, and can directly produce the copper-clad long carbon fiber composite conductor wire with bright surface and stable quality. However, the conductivity, mechanical properties, wear resistance, high temperature resistance and durability thereof are to be further improved, and the puncture resistance is also to be further improved.
