Copper busbars also have standards. Do you know what inspection criteria exist for copper busbars? Let the copper plate manufacturer introduce them to you!

Copper busbar, also known as copper mother line, copper main bar, or copper bus, grounding copper busbar, is made of copper material and is a long conductor with a rectangular or chamfered (rounded) rectangular cross-section.Widely used in the connection between conductors in high and low voltage distribution facilities. For example: distribution cabinets, transformers, high and low voltage switches, busbar trays, electronic radiators, electrical equipment,Components and other elements.

Due to copper's good conductivity, copper busbars are widely used in electrical equipment, especially in complete distribution devices; Generally, in distribution cabinets, U andV, W, and PE busbars all use copper busbars.

For processed copper busbars, acceptance should be carried out according to the following standards:

(1) Material: National standard T2 copper

(2) Copper content: approximately 99.95%.

(3) The surface of the copper busbar is smooth and flat, without cracks, peeling, slag inclusion, pores, or other defects.

(4) Surface finish 3.2

(5) Dimensional tolerance ±0.5mm

(6) Straightness ≤ 2mm/m

(7) No cracks on the surface when bent 90 degrees

(8) Hardness: HB≥65

(9) Tensile strength: ≥300N/mm²

(10) Density: At 20°C, the density of copper busbars is 8.95g/cm3

(11) Resistivity: ≤ 0.017772Ωmm²/m
