Customized Aluminium Busbars

Aluminum busbars have excellent conductivity – a good choice for busbars where weight is a primary consideration.

Lightweight solid busbars

Customized aluminum busbars

Aluminum with high purity has excellent electrical properties. For this reason, aluminum rails are used both as current conductors and for optimized heat transfer at contact surfaces. Pure aluminum produces a closed aluminum oxide layer (Al2O3) under given environmental conditions. This property makes aluminum very corrosion resistant to external influences. However, this oxide layer is not conductive. Therefore, aluminum busbars require thorough pretreatment and preservation.

EMS Aluminum Busbars Industry

From aluminum semi-finished product to lightweight busbar

Aluminum busbars are the lightweight alternative to copper busbars. Aluminum busbars have the advantage over copper that they are much lighter. The installation and also the handling of aluminum busbars is very easy due to the low weight. However, a low density also means that the cross-section, for the same amount of current, must be selected significantly larger compared to copper.The silvery light metal is ideally suited for all non-cutting manufacturing processes. Aluminum corrodes within a short time. For this reason, thorough pretreatment is important!

For the individual design of your busbars, use our engineering know-how – we look forward to hearing from you!

Determined according to DIN 43670

Current carrying capacity aluminum busbars

* Current load values: Ambient temperature 35 °C, AC current AC.

Heating of the busbar depending on: Current intensity, ambient temperature, heat dissipation, type of routing, installation, application Multiplication factor 1.72 when using 2 rails, multiplication factor 2.25 when using 3 rails in parallel arrangement.
