Air-type busway is a type of busway. The air-type busway housing is made of high-strength cold-rolled steel, cold-rolled into a corrugated structure in one process, which not only offers an aesthetically pleasing appearance but also significantly enhances the mechanical strength of the busway and the thermal stability of the system, effectively resolving the challenges of installing over large spans on construction sites. The air-type busway features a structure where conductors are separated from each other and from the housing, allowing for air insulation. Additionally, it incorporates insulating material for double insulation.

Air-type busway, mainly composed of the housing, insulating plug, and metal busbar, with the housing serving as dust protection and safety. The housing features ventilation holes for heat dissipation. The internal busbar can be single or double depending on the current size per pole. If the housing is metallic, it also provides grounding protection. From an insulation perspective, sufficient distance should be maintained for safety; from a heat dissipation standpoint, adequate space is required to ensure heat is dissipated into the air through convection.
