Embodiment 1
[0011] Such as figure 1 As shown, a high-conductivity copper-clad aluminum cable provided by the present invention includes an aluminum alloy core 1, a pure copper skin layer 2, a tin coating layer 3 and a silver coating layer 4, and the silver coating layer 4 is also coated with a layer of silver-plated fiber mesh 5. Finally, coat the outer periphery of the silver-plated fiber net 5 with 6 layers of insulation and a protective sheath 7; the mass percentages of alloying elements in the aluminum alloy core 1 are: Cu0.1%, Be0.02%, Mg0.2% , the rest are Al and unavoidable impurities; the skin layer 2 is made of pure copper material, the core layer 1 and the skin layer 2 are put into a heating furnace for preheating, and are filled with nitrogen protection; then the preheated skin layer is heated in an argon gas The protection is divided into the following: wrapping the core layer; under argon protective gas, spraying a tin layer 3 on the surface of the skin layer, and then sprayi...
