Indal Handbook For Aluminium Busbar [work] Instant

For high-reliability joints or connections to copper terminals, the handbook recommends silver plating or tin plating. Bolting Practices

: An overview of the physical and chemical properties of aluminium, highlighting its benefits like high strength-to-weight ratio and cost-effectiveness compared to copper.

During a short circuit, busbars are subjected to immense electrodynamic forces that can cause them to bend, vibrate, or even break. The handbook details how to calculate these forces to ensure the busbar and its supports have sufficient mechanical strength. Aluminium alloys used for busbars, such as the 6101 grade, are specifically chosen for their optimal combination of high electrical conductivity (around 55-60% IACS) and good mechanical properties, including a minimum tensile strength of approximately 170 MPa.
