Abstract

The invention discloses a mineral substance bus duct. The mineral substance bus duct comprises a bus duct body, wherein a seamless shell is arranged outside the bus duct body, the bus duct body comprises a bottom copper bar installation base and an upper copper bar installation base, the bottom copper bar installation base comprises a base plate, and a copper bar installation groove formed by sheet copper is formed in the base plate; inner clamping sawteeth are arranged in the installation groove, outer clamping sawteeth matched with the inner clamping sawteeth are arranged at the lower end of each copper bar, clamping grooves for installing the upper end of each copper bar are formed in the upper copper bar installation base, and the space between the copper bars is filled with dense and compact magnesia powder. The mineral substance bus duct is good in water resistance, high in reliability and easy to assemble.

Description

technical field [0001] The invention relates to a bus duct, in particular to a mineral bus duct. Background technique [0002] Now the busway casings on the market are all connected by two-piece or four-piece rivets and bolts, which cannot meet the waterproof requirements. The insulating layer is all made of resin film, which is easy to age and has a short service life. [0003] Now the fire-resistant busway on the market is all made of steel shell, four-piece, eight-piece (separated by multi-layer partition insulation layer) or assembled with bolts in other ways. It is assembled with about 40 sets of bolts around the bus duct per meter, making the bus duct unable to waterproof. Some manufacturers use mica paper or mica tape to cover the conductor to fill mineral powder, but during transportation and use, the powder leaks a large amount of powder from the cover plate and side plate bolt connection around the shell. A small number of manufacturers want to complete the proc...
