Air type bus duct is a type of bus duct. The shell of the air type bus duct is made of high-quality high-strength cold-rolled steel, which is cold-rolled into a corrugated structure in one go. It not only has a beautiful and generous appearance, but also greatly enhances the mechanical strength of the bus duct and the dynamic and thermal stability of the system, which can completely solve the problem of large-span installation on construction sites. The conductor of the air type bus duct is made of high-purity electrolytic copper, and the entire surface of the conductor is tinned to improve its resistance to oxidation and corrosion. After processing, it is heat shrink treated with PVC pipes, and insulated blocks are used to separate the phases and ground. The copper busbar is double insulated for protection, greatly improving its insulation performance, and then enclosed in a grounded metal shell.
Air type busbar trunking is mainly composed of an outer shell, insulated plugs, and metal busbars. The outer shell plays a role in dust prevention and protection. There are ventilation holes on the shell to complete the heat dissipation function, and the built-in busbar can be made into a single or double pole according to the current size. If the shell is made of metal, it also has the function of grounding protection. From the perspective of insulation, sufficient distance should be left for safety; From the perspective of heat generation, sufficient space should also be left for heat dissipation to ensure that heat is dissipated into the air through convection.
