Copper busbars

Conductive components for power distribution

Copper busbars are a key element in modern electrical installations, power distribution and control systems. The bars transfer current between components and systems, and their electrical and thermal properties directly affect

Material and conductor capacity

Copper busbars are typically manufactured from electrolytic copper (Cu-ETP) with high conductivity. Material purity is crucial because even small variations can

Machining processes – precision and stability

Copper busbars are machined through several processes that together ensure correct geometry, hole patterns, surfaces and surface quality.Cutting and adjustmentThe

CNC milling of hole patterns and geometries

Hole patterns are a critical element in copper busbars. Variations can affect electrical contact, assembly and heat generation.TORA’s CNC process

Bending – geometry and mechanical stability

Bending copper busbars requires precise processes, as copper is both soft and formable.An incorrect bend can cause:Uneven conductor widthInternal stressesChanges

Tin-plating, coating and insulation

Surface treatment plays an important role for copper busbars – both electrically and in terms of corrosion.Tin-platingUsed to improve contact

Deburring and finish

Edges and surfaces are checked and processed to ensure:True surfaces for correct contactNo sharp edgesFlatness of surfacesUniform finishThis is an
