Abstract
The utility model provides a kind of low-smoke non-halogen, the bundle conductor to press together including multi beam and the insulation sleeve being wrapped on the outside of bundle conductor, bundle conductor is made of conductor, the fire-resistant isinglass belt being wrapped on the outside of conductor and the insulated hull being wrapped on the outside of fire-resistant isinglass belt, insulation sleeve includes the fire-retardant band being wrapped on the outside of bundle conductor and the low smoke and zero halogen sheath being wrapped on the outside of fire-retardant band, and low smoke and zero halogen sheath uses low-smoke halide-free fireproof composite polyolefine material.The cable is nonflammable, and less toxic gas is generated after burning, is a kind of safe and reliable power cable.
Description
Technical field
The utility model is related to a kind of power cables.
Background technology
The application of low pressure fireproof power cable is more and more extensive, and cable will appear short circuit breakdown and cause fire when running,
Most low pressure fireproof power cable insulation and sheath are all made of flame-proof polyvinyl chloride material, in being granulated process, it is necessary to
The heavy metal compounds such as lead salt are added as stabilizer, using the halogen elements such as chlorine, bromine are largely contained as fire retardant.Cable is using
Event of fire in the process will produce the toxic gases such as a large amount of smog, carbon monoxide, hydrogen chloride, serious shadow when burning
It rings evacuating personnel and brings very big difficulty, and a large amount of uses of these materials to scene of a fire rescue and relief work, after the period scraps, still
Environment is caused seriously to pollute.
Utility model content
In order to solve the problems, such as that background technology, the utility model provide a kind of low smoke halogen-free fire retardant fire resistant electric power
Cable, the cable is nonflammable, and less toxic gas is generated after burning, is a kind of safe and reliable power cable.
In order to achieve the above objectives, the utility model adopts the following technical solution：
A kind of low-smoke non-halogen, which is characterized in that the bundle conductor that presses together including multi beam and
The insulation sleeve being wrapped on the outside of bundle conductor, bundle conductor is by conductor, the fire-resistant isinglass belt being wrapped on the outside of conductor and is wrapped in fire resisting
Insulated hull composition on the outside of mica tape, insulation sleeve include the fire-retardant band being wrapped on the outside of bundle conductor and are wrapped in outside fire-retardant band
The low smoke and zero halogen sheath of side, low smoke and zero halogen sheath use low-smoke halide-free fireproof composite polyolefine material.
Gap between bundle conductor and between bundle conductor and insulation sleeve is filled with glass fibre.
It is pasted with split-phase colour band on the outside of the insulated hull of each bundle conductor.
The utility model has the beneficial effects that：It is nonflammable, even if burning also only will produce a small amount of flue gas so that the electric power
The safety of cable greatly improves, and will not generate pollution to environment after scrapping.
Description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings
Fig. 1 is the structural schematic diagram of power cable described in the utility model；
Specific implementation mode
Explanation and specific implementation mode are further described the utility model below in conjunction with the accompanying drawings：
Embodiment 1
As shown in Figure 1, a kind of low-smoke non-halogen, including bundle conductor and packet that multi beam presses together
The insulation sleeve being rolled on the outside of bundle conductor, bundle conductor is by conductor 1, the fire-resistant isinglass belt 2 being wrapped on the outside of conductor 1 and is wrapped in fire resisting
The insulated hull 4 in 2 outside of mica tape forms, and insulation sleeve includes the fire-retardant band 6 being wrapped on the outside of bundle conductor and is wrapped in fire-retardant packet
Low smoke and zero halogen sheath 7 with 6 outsides, low smoke and zero halogen sheath use low-smoke halide-free fireproof composite polyolefine material, low-smoke non-halogen flame-retardant poly-
Olefin material is made of addition magnesium hydroxide and hydroxide in flame retardant polyolefine material.Between bundle conductor and bundle conductor and insulation sleeve
Between gap using glass fibre 5 fill.
For the ease of using, it is pasted with split-phase colour band 3 on the outside of the insulated hull of each bundle conductor, point for distinguishing each bundle conductor
Phase.
It will be recognized by those skilled in the art, can be to above-mentioned under the premise of without departing from protection scope of the present invention
Embodiment is carry out various modifications, changes and is combined, and thinks that this modification, variation and combination are the models in originality thought
Within enclosing.
