A busbar operating at 120°C in a dusty environment is a fire risk. Dust acts as a thermal blanket, preventing cooling. indal handbook for aluminium busbar hot
Aluminium busbars are the standard for power distribution due to their excellent conductivity-to-weight ratio and cost-effectiveness compared to copper. When selecting busbars for high-current or high-ambient-temperature environments (often referred to as "Hot" applications), specific alloy grades—historically championed by Indal—are required to prevent failure. rise, which is then derated based on site-specific
