Fire-resistant busway with heat dissipation rings

Abstract

The invention discloses a fire-resistant busway with heat dissipation rings. The fire-resistant busway comprises a shell, wherein the shell comprises an outer shell and an inner shell; the heat dissipation rings are uniformly arranged at the outer side of the shell; longitudinal adjustment mechanisms are arranged at the inner side of the shell and are fixed through first locking mechanisms; the side surface of the longitudinal adjustment mechanism is connected with a wiring frame; wire clamps are clamped on the wiring frame through clamping mechanisms; the top of the shell is movably connectedwith an upper cover plate through sliding mechanisms; the upper cover plate is fixed to the shell through second locking mechanisms; and heat dissipation devices are uniformly arranged at the top ofthe upper cover plate. According to the fire-resistant busway with the heat dissipation rings, the outer shell is light in weight, resistant to high temperature, good in thermal stability, resistant to mechanical vibration, low in thermal expansion coefficient, high in thermal conductivity and resistant to acid, alkali and salt erosion and has a fire-resistant function, and the inner shell has water corrosion resistance and good weather resistance, is free of flowing at high temperature and free of cracking at low temperature and has waterproofing and air-isolating functions.

Description

technical field [0001] The invention relates to the technical field of bus ducts, in particular to a fire-resistant bus duct with a cooling ring.
