Air-Insulated Busbar
Air + slot insulation · best heat dissipation · lowest cost
Air-insulated bus duct uses air together with slot insulation between conductors. Natural convection gives the best heat dissipation of the three busbar types, and it is the most economical choice for general power-distribution rooms.
