Problems solved by technology

The aluminum alloy conductor materials in the prior art are relatively excellent in electrical properties, corrosion resistance and mechanical properties, etc., but are still relatively poor in fatigue resistance, which is prone to quality problems and affects the service life or band of the aluminum alloy material. Therefore, the overall performance of aluminum alloy power cables is still poor
