Air busbar trunking is a kind of equipment used for power distribution and transmission. Its internal structure usually consists of conductors, insulating materials and a housing. The housing of the air busbar trunking is made of high-quality high-strength cold-rolled steel, which is formed into a corrugated structure through one-time cold rolling. It not only has an elegant and generous appearance, but also greatly enhances the mechanical strength of the busbar trunking and the dynamic and thermal stability of the system, which can completely solve the problem of long-span installation on construction sites.
Structural Features
The air busbar trunking is mainly composed of a housing, an insulating plug and a metal busbar. The housing plays a role in dust prevention and protection, and is also equipped with ventilation holes to complete the heat dissipation function. The built-in busbar can be made into a single one or two ones according to the current size. If the housing is made of metal, it also has the function of grounding protection. The conductor is made of high-purity electrolytic copper, the entire surface is tin-plated and treated with PVC heat-shrinkable tubes, and the phases and the ground are separated by insulating blocks to ensure double insulation protection.
Application Scenarios
The air busbar trunking is suitable for AC three-phase four-wire and three-phase five-wire systems, with a frequency of 50-60Hz, a rated voltage up to 380V, and a rated operating current of 100-5000A. It is mainly used for the connection between low-voltage distribution panels and large and medium-sized loads, and is widely used in modern workshops, factories and high-rise buildings.
