Solid Copper Busbar
A Hard Copper Busbar is a rigid, high-strength electrical conductor made from hard drawn copper such as T2 Hard Copper Busbar or C11000 Hard Copper Busbar. Unlike flexible busbars, the Solid Copper Busbar maintains its shape under load, providing long-lasting stability in fixed installations. With High Conductivity Copper busbar material, it ensures efficient electrical power transmission while offering outstanding mechanical durability.
The manufacturing process of a Hard Drawn Copper Busbar involves several precise steps:
Material Selection – Using high-purity electrolytic copper (≥ 99.9% Cu) with certified chemical composition to achieve ≥ 97% IACS conductivity.
Cold Drawing or Extrusion – Producing a rigid copper busbar with enhanced tensile strength.
Precision Cutting & Punching – Custom widths, thicknesses, and drilled holes for easy installation.
Surface Treatment – Optional tin-plating, nickel-plating, or silver-plating to improve corrosion resistance, conductivity, and wear resistance.
Hard Copper Busbars are widely used in:
Power plants and substations
Electrical switchgear and distribution cabinets
Industrial machinery electrical panels
UPS and backup power systems
Renewable energy installations (solar, wind, hydro)
Electroplating and electrolytic processing equipment
The T2 Hard Copper Busbar and C11000 Hard Copper Busbar are particularly favored in high-current, high-reliability environments where consistent performance is essential.
