Busbar is a multi-layer laminated structure connector, typically fabricated from high-conductivity materials such as copper or aluminum. It consolidates multiple electrical circuits to enable centralized power distribution and transmission, effectively replacing discrete cabling and significantly simplifying the internal wiring layout.

Featuring high current-carrying capacity, low impedance, excellent heat dissipation, and reliable connections, busbars are extensively used in power systems, electric motors, electronic control applications, and other associated fields.
