What is a copper bar?

A Copper Bar is a solid bar of copper metal crafted by Miners. It is used in blacksmithing plans, engineering schematics, and in the creation of Bronze Bars. This item is crafted by Miners with a skill level of 1. The miner must be at a forge to smelt the metal into bars. Smelting Copper stops giving skillups to Mining at 65.

Can you still use copper bus bars?

The copper bus bars heated up so much some turned dark ,burnt. Can you still use them? Got pictures? If the discoloration is just in the surface, clean it up until you get to good copper and the bus bar back to service. If I can do it, you can do it. Recently had some bad cells in a 16 cell 48v pack.

How much current does a copper busbar need?

The current is an estimated continuous rating and plotted versus the cross-sectional area in mm 2. The gradient of the “straight line fit” shows that 5.9A/mm 2 is a rough estimate for copper busbar size. However, to be on the safe side of this I would initially size at 5A/mm 2 before doing the detailed electrothermal analysis.

What is the difference between copper and aluminium busbars?

Compared to copper busbars aluminium offers a weight and cost save, but requires an increase in cross-sectional area of ~62%. Hence aluminium busbars need more volume for packaging. The highest conductivity is achieved by high purity aluminium (purity of 99.9 wt% Al and higher) in soft temper.

What is a good size for a copper busbar?

The gradient of the “straight line fit” shows that 5.9A/mm 2 is a rough estimate for copper busbar size. However, to be on the safe side of this I would initially size at 5A/mm 2 before doing the detailed electrothermal analysis. An important aspect to consider in all busbar designs is to consider the environment and the materials.

What causes a battery to corrode?

Corrosion can be caused because the air used to cool the battery comes from the cabin that can be hot, cold, moist etc. When rebuilding always use a drop of Stabilant 22A on the nut/stud. Image supplied and copyright of Salvage Wire. In reality the connecting surfaces are not perfectly flat.
