At present, the generator has become the first choice of life. As an accessory of the generator, the use of the conductor wire is indispensable, and the performance of the conductor wire directly influences the normal and well-known stability and the cycle service life of the generator. Therefore, development of a conductor wire for a generator excellent in combination properties is necessary.
The ideal conductor wire for the generator should have excellent conductivity, mechanical properties, wear resistance, high temperature resistance and durability at the same time. However, the above properties of existing conductor wires cannot meet the higher standards at the same time, due in large part to the selection of the component formulation of the conductor wires.

For example, chinese patent No. CN 106180649A discloses a method for preparing copper-clad long carbon fiber composite conductor wire, which is characterized by comprising the following steps: one end of the long carbon fiber is fixed on the guide rod through the center of a heating casting mold hole, and the other end is wound in a vacuum furnace at the upper part of the crucible, so that the heating casting mold, the induction coil and the guide rod are centered; smelting pure copper at 1100-1200 deg.c and vacuum degree less than 1 Pa; argon is filled into the furnace to balance the pressure inside and outside the furnace; preparing a copper-clad long carbon fiber composite conductor bar blank with the diameter of 8.0-12.0mm at the blank drawing speed of 50-150mm/min at the cooling water flow rate of 500-1500L/h and the cooling water temperature of 20-30 ℃; and drawing the copper-clad long carbon fiber composite conductor bar blank for 2-6 times at room temperature to form the copper-clad long carbon fiber composite conductor wire. 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 electrical conductivity, mechanical properties, wear resistance, high temperature resistance and durability thereof are to be further improved, and the puncture resistance is to be further improved.
Therefore, it is necessary to adjust the composition formula of the conventional conductor wire for a generator in order to obtain a conductor wire for a generator excellent in conductivity, mechanical properties, wear resistance, high temperature resistance, and durability and excellent in breakdown resistance.
