Tin Plated Copper Bus Bars

We manufacture and export Tinned coated Copper Bus Bars. In electrical power distribution, a bus bar is a strip of copper or aluminium that conducts electricity within a switchboard, distribution board, substation or other electrical apparatus.

The size of the bus bar determines the maximum amount of current that can be safely carried. Bus bars can have a cross-sectional area of as little as 10 mm2 but electrical substations may use metal tubes of 50 mm in diameter (1,963 mm2) or more as bus bars.

For rigid electrical connections, Tinned coated Copper Bus Bars offer a very efficient solution. Resistivity in copper bars i s very low, 25 in^2 bar 1 foot long is only 0.0000329 Ohms – roughly 8 Watts lost at 500 Amps.

Where to use Tinned coated Copper Bus Bars:

Very rigid high power connections.

Connection of Field/Armature on Motor Terminals

Where not to use Tinned coated Copper Bus Bars:

Anywhere that needs flexible connections.

Between battery terminals. (May cause undue stress to terminals.)

Shape / Size:

Favor thin and wide.

Cross sectional area should be same as equivalent wiring

We also make different shape of Bus Bar as shown in the image on the right side
