The intensive bus duct comprises flame-retardant separator plates, insulators and hot shrinkage pipes, wherein the outer sides of upper cover plates are provided with upper cover plate fastening bolts, the upper cover fastening bolts penetrate the inner sides of the upper cover plate, the flame-retardant separator plates are installed at the inner sides of side plates, conductors transversely penetrate two sides of each flame-retardant separator plate, the outer sides of the side plates are provided with housing insulation fasteners, the outer sides of the conductors are provided with insulators and the hot shrinkage pipes, inner casing fasteners are installed at one side of each flame-retardant separator plate, a lower cover plate is arranged at the bottom portions of the side plates, the lower cover plate and the side plates are connected through bolts, one end of each conductor is provided with a joint insulator separator plate and a joint fastening hole, and the joint fastening holes are arranged at the centers of the conductors. The bus duct is provided with a housing made of an aluminum-magnesium alloy material, the anticorrosion performance is good, the housing is coated with a fireproof material, the inner cavity is provided with the two flame-retardant separator plates, the fireproof effect is excellent, radiating fins are inlaid in the inner sides of the side plates, and the heat dissipation effect is improved.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a dense busway. Background technique [0002] With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life is increasing rapidly, especially the emergence of many high-rise buildings and large workshops. The traditional cables used as power transmission wires can no longer meet the requirements in large current transmission systems. The parallel use of multiple cables brings a lot of inconvenience to the site installation and construction connection. As a new type of distribution wire, the bus duct emerged at the historic moment. Compared with the traditional cable, the bus duct fully demonstrates its superiority in the transmission of large currents. The contact resistance and temperature rise of the joints at the two ends and the outlet of the distribution port, and the use of high-quality insulating materials in the ...
