Fire-resistant low-voltage bus duct

Abstract

The invention discloses a fire-resistant low-voltage bus duct. The fire-resistant low-voltage bus duct comprises a shell body, wherein the outermost side of the shell body is provided with an anticorrosive material layer, the inner side of the anticorrosive material layer is provided with a fire-resistant material layer, the lower portion of the fire-resistant material layer is provided with a load-bearing material layer, the inner lower portion of the load-bearing material layer is provided with a first insulating material layer, the top end of the shell body is connected with a cover plate,the shell body and the cover plate are both provided with connecting grooves, and the connecting grooves are internally slidably connected with partition frames. The fire-resistant low-voltage bus duct has the advantages that busbars installed internally are more loose, thereby providing convenience for heat dissipation, a multilayer insulating structure is adopted to separate the busbars, therebybeing capable of effectively preventing the busbars from being inferred by one another, the shell body is compounded by adopting various materials, thereby ensuring the integral corrosive resistanceand fire resistance, the integral connection is more tight, thereby being capable of effectively preventing the outside water and dust from entering the bus duct, and the safety of the use is ensured.

Description

technical field [0001] The invention relates to the technical field of bus ducts, in particular to a fire-resistant low-voltage bus duct. 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 multi-channel cables brings a lot of inconvenience to the on-site installation and construction connection. Superiority, although there are some bus ducts on the market at present, but the structure is relatively simple, which makes the internal bus contact more closely, which easily makes the temperature inside the bus duct too high, and may cause interference between the bus ducts, and at the same time Due to the material selection, the fire resistance of ...

[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 multi-channel cables brings a lot of inconvenience to the on-site installation and construction connection. Superiority, although there are some bus ducts on the market at present, but the structure is relatively simple, which makes the internal bus contact more closely, which easily makes the temperature inside the bus duct too high, and may cause interference between the bus ducts, and at the same time Due to the material selection, the fire resistance of the busway is low, so it cannot meet the needs of people.
