To keep your busbars from running too hot, the Indal Handbook suggests focusing on the . Heat is lost through: Convection: Air moving around the bar.
How the busbar reacts to electrical loads. indal handbook for aluminium busbar hot
You can use a larger aluminum bar to match copper’s conductivity and still save significantly on costs. To keep your busbars from running too hot,
Aluminum is 30% the weight of copper, reducing the mechanical stress on supports when the metal expands due to heat. You can use a larger aluminum bar to
While hot-rolled aluminum is excellent for general conductivity, most high-precision busbars undergo a final to achieve the T6 temper (solution heat-treated and artificially aged). The Indal Handbook provides specific data on how the "hot" phase of manufacturing influences the final electrical conductivity (typically around 61% IACS). 4. Managing Temperature Rise (The "Hot" Factor)
Heat emitting from the surface (enhanced by painting busbars matte black). The handbook provides the formula: Total Heat Loss (W) = Convection Loss + Radiation Loss
