Abstract

The invention discloses a low-smoke halogen-free high-flame-retardant fire-resistant environmentally-friendly cable which comprises multiple conductors, wherein the multiple conductors are respectively wrapped with an inner wrapping layer which is formed by wrapping double-layer mica tapes, an insulating layer, a cable core formed by mutually twisted and bundled multiple conductors wrapped on the insulating layer and an outer wrapping layer which is formed by wrapping glassfiber tapes and mica tape and wrapped on the cable core in sequence, wherein a packing layer is arranged between the outer wrapping layer and the cable core, a corrugated pipe is wrapped on the outer wrapping layer, and a sheathing layer is wrapped on the corrugated pipe. The cable provided by the invention is reasonable in structure and design, the inner and outer wrapping layers respectively use the double-layer mica tapes, the glassfiber tap and the mica tape, and the aluminum corrugated pipe can be used as a fire protection layer, thus the heat-resistant performance and fire-resistant performance can be obviously improved, and the service life of the cable can be prolonged.

Description

The fire-resistant environment-friendly cable of a kind of low-smoke bittern-free highly fire-proof
Technical field:
The present invention relates to field of cables, relate in particular to the fire-resistant environment-friendly cable of a kind of low-smoke bittern-free highly fire-proof.
Background technology:
Along with occasions such as urban skyscraper, subway and nuclear power station are increasingly high to the flame-retardant performance requirement of cable; Therefore the hydrogen halide that the while halogen containing material discharges when fire has designed the fire-resistant environment-friendly cable of low-smoke bittern-free highly fire-proof to the secondary injury that the person, equipment cause.
The flame-retardant characteristic of original cable does not reach the demand of actual working environment.
Summary of the invention:
In order to remedy the deficiency of prior art, the purpose of this invention is to provide the fire-resistant environment-friendly cable of a kind of low-smoke bittern-free highly fire-proof, reasonable in design, little to the pollution of environment, satisfy the demand of actual working environment.
Technical scheme of the present invention is following:
The fire-resistant environment-friendly cable of low-smoke bittern-free highly fire-proof; Comprise several conductors, it is characterized in that: several conductors are enclosed with interior lapping layer, the insulating barrier of the wrapped formation of double-deck mica tape outward respectively successively, and the mutual stranded bunchy of several conductors of wrap insulate layer constitutes cable core; Cable core is wrapped with the outer lapping layer of glass fibre belt and the wrapped formation of mica tape; Be provided with packed layer between outer lapping layer and the cable core, outer lapping layer is wrapped with bellows, and bellows is wrapped with restrictive coating.
The fire-resistant environment-friendly cable of described low-smoke bittern-free highly fire-proof is characterized in that: described insulating barrier adopts low-smoke halogen-free polyolefin.
The fire-resistant environment-friendly cable of described low-smoke bittern-free highly fire-proof is characterized in that: described packed layer adopts the glass rope to fill formation.
The fire-resistant environment-friendly cable of described low-smoke bittern-free highly fire-proof is characterized in that: described bellows is the aluminium bellows.
Advantage of the present invention is:
Reasonable in design of the present invention adopts the wrapped formation of double-deck mica tape, glass fibre belt and mica tape respectively at inside and outside lapping layer, and the aluminium bellows is as fireprotection layer, and resistance to elevated temperatures, fire resistance obviously promote, and have prolonged the useful life of cable.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
The fire-resistant environment-friendly cable of low-smoke bittern-free highly fire-proof; Comprise several conductors 1, several conductor 1 outer interior lapping layer 2, insulating barriers 3 that are enclosed with the wrapped formation of double-deck mica tape respectively successively, several conductors 1 mutual stranded bunchy of wrap insulate layer 3 constitutes cable core; Cable core is wrapped with the outer lapping layer of glass fibre belt 4 and mica tape 5 wrapped formations; Be provided with packed layer 6 between outer lapping layer and the cable core, outer lapping layer is wrapped with bellows 7, and bellows 7 is wrapped with restrictive coating 8.
Insulating barrier 3 adopts low-smoke halogen-free polyolefin.
Packed layer 6 adopts the glass rope to fill formation.
Bellows 7 is the aluminium bellows.
Concrete structure of the present invention:
1, cable conductor: loaded current guarantees electric power transfer.
2, double-deck mica tape: utilize the characteristic of high temperature resistant, the anti-burning of mica tape, high insulation, under the impaired situation of insulation fire, still can guarantee electric power transfer.
3, low-smoke halogen-free polyolefin insulation: not halogen-containing element can not produce hydrogen halide during burning; Its fire-retardant oxygen index can reach more than 32, has high flame retardant and good electrical insulation properties.
4, the glass rope is filled: be a kind of high flame retardant, high temperature resistant filling, can improve the comprehensive oxygen index of cable.
5, glass fibre belt+mica tape is wrapped: utilize the anti-burning of glass fibre belt, resistant to elevated temperatures characteristic, be used for fixing the mica refuge floor, guarantee the integrality of mica layer.
6, aluminium bellows welding overcoat: be used to protect that built-in electrical insulation does not receive the exterior mechanical damage and the fireprotection layer during as fire.
7, low-smoke halogen-free polyolefin sheath: not halogen-containing element can not produce hydrogen halide during burning; Its fire-retardant oxygen index can reach more than 36, has high flame retardant and favorable mechanical physical property.
The not halogen-containing element of employed material in the above construction of cable, the comprehensive oxygen index of the cable of this design can reach
To 70, can satisfy the instructions for use of cable special occasions.
