(Summary description)The outer casing of the busway should be selected to meet the requirements of mechanical load. The outer joints of the outer casing can be welded or bolted. However, the outer casing of the bolted joint should ensure electrical continuity. The fasteners should have good plating. It should be covered with heat-resistant flame-retardant coating. The coating can prevent atmospheric corrosion. The coating should be uniform, neat and beautiful, without blistering, cracking and other defects. The closed dense busbar should be used as a type test low-voltage switchgear and control equipment. The structure of the enclosed busbar is safe and reliable, easy to install, easy to maintain, and can withstand the mechanical, electrical and thermal stresses specified by the standard. Perform electrostatic spray surface treatment. The thickness of the outer shell material is aluminum-magnesium alloy, the thickness of the sheet is ≥4.5mm, and the thickness of the cold-rolled galvanized steel sheet is ≥2.5mm.

Information
The outer casing of the busway should be selected to meet the requirements of mechanical load. The outer joints of the outer casing can be welded or bolted. However, the outer casing of the bolted joint should ensure electrical continuity. The fasteners should have good plating. It should be covered with heat-resistant flame-retardant coating. The coating can prevent atmospheric corrosion. The coating should be uniform, neat and beautiful, without blistering, cracking and other defects. The closed dense busbar should be used as a type test low-voltage switchgear and control equipment. The structure of the enclosed busbar is safe and reliable, easy to install, easy to maintain, and can withstand the mechanical, electrical and thermal stresses specified by the standard. Perform electrostatic spray surface treatment. The thickness of the outer shell material is aluminum-magnesium alloy, the thickness of the sheet is ≥4.5mm, and the thickness of the cold-rolled galvanized steel sheet is ≥2.5mm.
 
The selection of dense busbar housing should meet the requirements of mechanical load (the thickness of the board should meet the technical requirements), the hardened riveting method is adopted between the interconnecting parts of the outer casing, the coating is well coated with the fastener, and the surface coating of the outer casing is treated by electrostatic spray. The color is computer ash, the coating can prevent atmospheric corrosive agent and meet the fireproof requirements, the appearance is uniform, neat and beautiful, no blistering, no cracks, etc.
 
Busbar trunking emerged as a new type of distribution cable. Compared with the traditional cable, it is fully demonstrated in the large current transmission. At the same time, due to the adoption of new technologies and new processes, the busbar slots are greatly reduced. The contact resistance and temperature rise at the joints and the junctions of the junctions, and the use of high-quality insulation materials in the busway, thereby improving the safety and reliability of the busway and improving the overall system.
 
The busway is a busbar system consisting of a metal plate as a protective casing, a conductive row, an insulating material and related accessories. It can be made into a plug-in type closed busbar with a plug-in junction box at intervals, or a feed-type enclosed busbar without a splitter box in the middle. In the power supply system of a high-rise building, the power and lighting lines are often arranged separately, and the busway is installed as one or more turns in the electrical shaft along the wall. According to the application, the busway is generally composed of the starting busway, the straight-through busway L-type vertical (horizontal) curved busbar, the Z-type vertical (horizontal) offset busbar, the T-type vertical (horizontal) three-way busbar, and the X-type vertical) It consists of busbar, variable capacity busway, expansion busway, terminal head, terminal junction box, plug-in box, busbar slot related accessories and fastening devices. The busway can be divided into three types: air-type busbar slot, dense-insulated busbar slot and high-strength plug-in busway.
