[0002] A prefabricated cast fire-resistant bus duct is an important device used in the power system for installing and protecting power buses. This duct is usually made of high-temperature and fire-resistant materials to ensure the safe operation of the power system in a high-temperature environment.

[0003] According to a publicized earthquake-proof cast fire-resistant bus duct (publication number: CN 107332183 A), it includes several cable ducts for placing cables, an insulating and waterproof body for placing the cable ducts, a fireproof board arranged outside the insulating and waterproof body, the fireproof board is closely attached to the insulating and waterproof body through an inner shell, an outer shell is fixed to the outside of the inner shell by screws, a filler is filled in the gap between the inner shell and the outer shell, and several fireproof liquid tanks for placing fireproof liquid are equidistantly distributed at the top of the bus duct. For the earthquake-proof cast fire-resistant bus duct of the present invention, insulating resin is cast outside the cable duct, so as to achieve the insulating function and have the waterproof function at the same time; the fireproof board is enclosed inside the shell, which can effectively prevent the damage of the fireproof board, thus ensuring the normal fireproof performance. A fireproof liquid tank is arranged at the top of the shell, and when heated, the fireproof liquid is sprayed into the bus duct to achieve the fireproof purpose. Soft pads are arranged between the inner shell and the outer shell, which can play a role in earthquake prevention. However, this earthquake-proof cast fire-resistant bus duct cannot make its fireproof performance better and needs to be improved. Content of the Utility Model
