Copper busbar (copper flat bar)

Copper busbar — also called copper bus bar or copper flat bar — is the solid rectangular conductor used to carry high current in switchboards, distribution panels and busduct (busbar trunking) systems.

We supply high-conductivity copper busbar in full-round-edge (FR) and slightly-round-edge (SE) profiles, in tempers from annealed to hard. Exact width × thickness combinations, lengths and availability are confirmed with each quotation.

FR and SE busbar sizes
Width 9.53–260 mm × thickness 2.5–100 mm
Standards
JIS, EN, ASTM, AS/NZS, TIS
Temper
Annealed, ¼ hard, ½ hard, hard

Copper sheet, rod and bar

Copper sheet and strip are supplied to JIS H 3100 in C1100 (tough-pitch) and C1220 (phosphorus-deoxidised) grades. Round and hexagon copper bar is available from 6.35 to 100 mm diameter for machined and electrical parts.
