Abstract
The invention discloses an intensive fire-resistant bus duct comprising a bus-bar, external H-shaped profiles, an internal H-shaped profile, an internal U-shaped profile, and external U-shaped profiles. The two external H-shaped profiles and the two external U-shaped profiles are spliced by bolts into a fully-closed integral structure. The upper and lower sides of the bus-bar are fixed by the internal H-shaped profile. The left and right sides of the bus-bar are fixed by the internal U-shaped profile. Connecting side plates protecting the bus-bar are arranged at the two ends of the external H-shaped profiles. The space between the external H-shaped profiles and the internal H-shaped profile and the space between the internal U-shaped profile and the external U-shaped profiles are filled with fireproof filler. The bus duct adopts a two-layer shell of which the surface is spray-coated with fireproof plastic, and the space between the two layers is filled with a fireproof plate and fireproof cotton, so that double protection is offered to the bus-bar, and the protection grade is strengthened. Moreover, the bus-bar is coated with a mica tape, which further ensures the flame resistance of the bus-bar. The intensive fire-resistant bus duct is safe and reliable.
