Abstract
The utility model relates to a flame-resistant metal flexible pipe with an insulating inner, mainly used as a protective pipe for electric wires and cables. The utility model is formed by that the inner wall of a common metal flexible pipe 1 is recombined with an insulating plastic layer 2. As a result, the utility model has the advantages that the phenomenon that the old common metal flexible pipes abrade the electrical wires at threading time is improved, insulating property and fire retardant performance are enhanced, and threading is more convenient and smooth than before, work efficiency is enhanced, and quality is ensured for the electrical wires.
Description
The utility model relates to the fire-retardant metal hose of a kind of insulation.Main protective casing as electric wire.
The existing metal hose that is used for the electric wire protective casing still uses the common metal flexible pipe.Wearing and tearing to electric wire during threading are very big, and insulation, poor fire, have serious hidden danger.
The purpose of this utility model is to provide the metal hose of a kind of insulation, good flame resistance.
The purpose of this utility model is achieved in that the fire-retardant metal hose of a kind of interior insulation, is composited by outer layer metal flexible pipe and primary insulation plastic layer.
Compare with the common metal flexible pipe, the utility model is behind metal hose inwall compound inslation plastic layer, when having improved common metal flexible pipe threading in the past to the wear phenomenon of electric wire, insulating properties and fire resistance have been improved, and threading is than convenient, smooth and easy greatly in the past, improve work efficiency, guaranteed the electric wire quality.
Fig. 1 is a general structure schematic diagram of the present utility model.
Below in conjunction with accompanying drawing the utility model being done one describes in detail:
As Fig. 1, the fire-retardant metal hose of a kind of interior insulation is at the compound one deck ambroin of common metal flexible pipe 1 inwall layer 2.
Flexible pipe of the present utility model outer 1 is the galvanized steel belt, and thickness is 0.35～0.5mm.Internal layer 2 is 105 ℃ of flame-proof polyvinyl chloride PVC insulating barriers,
Insulation of the present utility model, good flame resistance:
Insulation resistance: the insulation resistance between plastic layer and the metal hose is greater than 20M Ω.
Dielectric voltage withstand: the dielectric strength that exchanges that can bear 1500V, 50HZ between plastic layer and the metal hose, last 1min and do not take place to puncture or scintillation.
Fire resistance: plastic layer index 〉=28%.
Claims (3)
1, the fire-retardant metal hose of a kind of interior insulation is characterized in that it is composited by outer layer metal flexible pipe (1) and inner plastic layer (2).
2, the fire-retardant metal hose of a kind of interior insulation according to claim 1 is characterized in that metal hose (1) is a galvanized steel strip.
3, the fire-retardant metal hose of a kind of interior insulation according to claim 1 and 2, ambroin layer (2) is the polyvinyl chloride insulation layer in it is characterized in that.
