COPPER SOLID BUSBARS

 

 

SPS offers a range of standard solid copper bars in the standard length of 4 m. The bars are also holed, bent or cut to length on request, and you can also find a range of different insulators and busbar supports from page 20 onwards in catalog. Hole size, number and arrangement in accordance with your specifications.

Standards

The DIN standards DIN 43670 and DIN 43671 outline the ampacity for conductors made of aluminum and copper under various conditions in tabular form. Correction factors take account of deviating conditions. These factors are listed for:

- Conductivity-dependent load changes

- Different temperatures

- Different bar orientation and routing

- Geometry-based change for AC applications

- Height changes

DIN 43670 lists the values for aluminum busbars, and Part 2 of this standard specifies the continuous ampacity values for copper- clad busbars made of aluminum. DIN 43671 lists the corresponding values for copper busbars.
