[0002] Composite busbars are important power supply devices in modern industrial production, and play a key role in the power transmission of mobile equipment. With the improvement of production efficiency and equipment complexity, higher requirements are placed on the wear resistance of busbars. Composite busbars are usually composed of conductor materials, insulating materials and wear-resistant layers. The conductor design adopts a multi-strand twisted wire structure. The flexibility and wear resistance of the conductor are improved through reasonable twisting angle and pitch design. The insulating part mostly adopts a multi-layer structure to ensure the stability and safety of the busbar in complex environments. The wear-resistant layer is attached to the surface of the busbar by spraying or hot pressing to ensure a close bond with the conductor and the insulating part.
