Copper Threaded Busbars | Alloy Trade Busbars

Threaded Copper Busbars

• Electrolytic Copper grade
• Rounded corners offer smooth handling
• Thickness – from 1.8 to 9 mm
• Length – from 900 to 2100 mm

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

Coatings like Silver, tin or nickel plating for copper bus bars is necessary in high temperature applications. At DC to 60Hz there is some controversy as to which plating is the best because while silver has the highest conductivity, it is also more noble than copper so it will actually accelerate corrosion wherever the plating gets scratched.
