An electric busbar is a critical component in modern electrical power distribution systems. Designed to efficiently collect and distribute electrical current, a busbar system provides a safe, compact, and low-resistance alternative to traditional cable wiring. Electric busbars are widely used in electrical panels, battery systems, industrial equipment, EVs, and energy storage systems.
As a professional manufacturer, we supply custom busbars, including Copper Busbar, aluminium busbar, laminated copper busbar, and insulated Flexible Busbar, engineered for high-current and long-term reliability.

An electric busbar (electrical bus bar) is a rigid or flexible metallic conductor—typically made from copper or aluminum—used to distribute electrical power within an electrical busbar system.
Compared with cables, a bus bar electric solution offers:
Lower electrical resistance
Higher current capacity
Better heat dissipation
Cleaner and more reliable electrical connections
Electric busbars are the backbone of bus bar electrical designs in switchgear, electrical panels, and battery assemblies.
The production of a copper electrical busbar or aluminium busbar typically follows these steps:
Material Selection
High-conductivity copper (C1100/C1020) or aluminum (6101/6063).
Cutting & Forming
Precision cutting, bending, punching, or CNC machining based on drawings.
Surface Treatment
Tin plating, silver plating, nickel plating, or insulation coating to improve conductivity and corrosion resistance.
Lamination & Insulation (Optional)
For laminated copper busbar or Insulated Copper Busbar, conductive layers are bonded with insulation films to reduce inductance.
Quality Inspection
Dimensional inspection, conductivity testing, and current-load verification.
This process ensures each busbar electrical product meets IEC, UL, or customer-specific standards.
