Busbars

They are usually used to connect outdoor equipments at substations and indoor in enclosures, allowing to conduct high currents in a reliable and safe way.

They are mostly aluminum or copper due to their low resistance attribute.

Common sizes:

AxB (mm)	AxB (mm)
25x3	50x6
25x6	50x10
32x3	60x6
38x3	75x6
38x6	100x6

We can supply them following special curve, weld and holes requirements and including any accesory to easy fit.

Special uses

Tubes and metal profiles

In some facilites it is more suitable to install particular bar-geometries.

We can supply any size, shape and even special structures to fit your high-current connections.

Any of these can be manufactured using different alloys depending on special requirements:

ALLOY	ISO/GRADE	DESCRIPTION	ALLOY	ISO/GRADE	DESCRIPTION
Oxygen free high conductivity copper	Cu-OF/102	Specific type of copper where high electrical conductivity is required.	Electrolytic copper	Cu-ETP/110	Coductivity rating of 100% IACS and 99.9% pure. It has 0.02%-0.04% oxygen content.
Cap copper	CuZn5/210	Nominal composition of 95% copper and 5% zinc. Slightly greater strength and ductility than Cu-ETP.	High phosphorous deoxidized copper	Cu-DHP/122	Excellent welding properties and hydrogent embrittlement high resistance.
Red brass	CuZn15/230	85% copper and 15% zinc. Excellent resistance to stress-corrosion cracking and good ductility.	Muntz metal	CuZn40/280	60/40 copper alloyed with zinc. It has excellent hot-working properties.
Cadmium copper	CuCd1/162	99% copper and 1% cadmium. It improves copper's strength with minimal electrical conductivity decrease.	Commercial bronze	CuZn10/220	90% copper and 10% zinc. It has very good cold formability like bending and stamping.
Brass	CuZn35/270	65% copper and 35% zinc. It has high strength and plasticity being very usual in many manufactured parts.	Phosphor bronze	CuSn5/510	Contains 95% copper and 5% tin. It has an excellent combination of strength, corrosion and wear resistance.
Silicon bronze	CuSi3Mn/655	Well regarded for their combination of strength, corrosion and heat resistance.	Leaded free cutting brass	CuZn36Pb3/360	Ideally suited for high speed machining, giving special details in thread rolling and knurling characteristics.
Heat treatable copper alloy	CuNi2Si/651	It is used in applications where heat treatment is necessary, which increases strength and electrical conductivity.	Naval brass	CuZn40Si/470	It is known for their combination of strength, corrosion resistance and formability.
