Air-type busway is a type of busway. The air-type busway housing is made of high-quality cold-rolled steel, cold-rolled into a corrugated structure in one process, which not only looks aesthetically pleasing but also significantly enhances the mechanical strength of the busway and the thermal stability of the system, effectively solving the problem of large-span installation at construction sites. The busbars of the air-type busway are made of high-purity electrolytic copper, with the conductor surface fully tin-plated to improve its resistance to oxidation and corrosion. After processing, it is heat-shrink wrapped with PVC tubes, insulated between phases and to ground with insulating blocks, providing double insulation protection for the copper busbars, greatly enhancing the insulation performance, and then enclosed in a grounded metal housing.。
