Abstract
The utility model relates to a fire-resisting bus slot, which is characterized in that insulation between the surface layers of a bus row is a casing of fire-resisting thermal shrinking; the shape of the cross section of the bus row is a smooth and transitional rectangle with round angles at four corners; an insulating spacer on the bus slot is made from glass fiber reinforced material; the surface of an insulated bolt is poured with epoxy glass cloth. The bus slot can reduce the propagation speed of a fire hazard and decrease smoke density, and corrosive gas can not be generated in the combustion process.
Description
The utility model relates to a kind of bus duct, especially flame retardant type.
Interlayer insulating film is all established on the exclusive surface of bus duct median generatrix, and insulating barrier is that the band shape that adopts the winding processing technology that materials such as polyvinyl chloride, politef are made is wrapped on the bus row.Since bus row be many together intensive, expand with heat and contract with cold repeatedly in the use, constantly strengthen friction, can damage the winding insulating barrier; Since be to twine insulation, its wrapped Duplication of putting up, and lapping layer even tension degree, and the existence of the air in the lapping layer will directly influence the electric property of bus duct; Twine insulation because anti-temperature level does not reach requirement, also easily heating is aging.In addition, because insulating material is the high polymer of halogen-containing element,, cause " fire secondary disaster ", and consequence is even more serious in case burning will produce a large amount of smog and pernicious gas.
The purpose of this utility model designs a kind of flame retardant type bus duct at above-mentioned defective exactly, can delay the speed of bus duct burning, reduces the smoke density that burning produces, and does not produce corrosive harmful substance in the combustion process.
The purpose of this utility model is realized by the following technical programs:
To change oxygen index into be 31 to the layer insulation of every bus row's outer surface by twining band in the bus duct, and the thermal contraction casing tube of halogen-containing element not.Bus row's cross sectional shape be designed to cross section be four angles be fillet and smooth transition apart from shape.Cross-over block adopts the glass fiber reinforcing material to make, insulation screw surface casting epoxy glass fabric.
Technical characterstic of the present utility model and result of use:
1, the layer insulation oxygen index is up to 31, and is nonflammable, and can not produce corrosive gas after the burning, and smokescope is low, and the people can see the distance in 5～7 meters in the place ahead when fire takes place.
2, the exclusive surperficial rounding of bus is smooth, is in operation to produce most advanced and sophisticated electric field discharge, and can not injures insulating barrier;
3, cross-over block has fire-retardant preferably (oxygen index is up to 40.5) characteristic.
4,, thereby further guarantee fire-retardant quality, electric property and the mechanical strength of flame retardant bus groove because insulated bolt surface casting epoxy glass fabric forms flame retardant insulation.
Accompanying drawing and description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
1 is to connect cover plate, the 2nd among the figure, insulating barrier, the 3rd, and fastening bolt, the 4th, cross-over block, the 5th connects side plate, the 6th, insulated bolt.
Accompanying drawing 2 is the A-A cutaway views in the accompanying drawing 1.
7 is to connect cover plate, the 8th among the figure, connects side plate, the 9th, flame-retardant heat shrinkable sleeve, the 10th, bus row.
Claims (3)
1, a kind of flame retardant type bus duct is characterized in that it is 31 and the thermal contraction casing tube of halogen-containing element not that an oxygen index is established on the exclusive surface of bus.
2, the flame retardant type bus duct of narrating according to claim 1 is characterized in that bus horizontal row cross sectional shape is four rectangles that the angle is fillet and smooth transition.
3, the flame retardant type bus duct of narrating according to claim 1 is characterized in that cross-over block adopts the glass fiber reinforcing material to make insulated bolt surface casting epoxy glass fabric.
