Abstract
The utility model discloses a LOSH (Low Smoke Zero Halogen) highly-inflaming-retarding fire-proof environment-friendly cable including a plurality of conductors. The conductors are wrapped with inner cladding layers formed by coiling double-layer mica tapes, and insulation layers respectively. The conductors wrapped in the insulation layers twist with each other into beam, thereby forming a cable core. The cable core is wrapped with an outer cladding layer composed of a glass fiber tape and a mica tape. A filling layer is arranged between the outer cladding layer and the cable core. The outer cladding layer is wrapped with a corrugated pipe. The corrugated pipe is wrapped with a sheath layer. The LOSH highly-inflaming-retarding fire-proof environment-friendly cable in the utility model is reasonable in structural design. The inner cladding layer and the outer cladding layer are both formed by coiling the double-layer mica tape, the glass fiber tape and the mica tape respectively. The aluminum corrugated pipe functions as a fireproof layer. Thus, the high temperature resisting performance and the inflaming-retarding performance are improved obviously. And the service lifetime of the cable is prolonged.
Description
Technical field:
The utility model relates to field of cables, relates 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.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides the fire-resistant environment-friendly cable of a kind of low-smoke bittern-free highly fire-proof, and reasonable in design is little to the pollution of environment, satisfies the demand of actual working environment.
The technical scheme of the utility model 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.
The utility model has the advantages that:
The utility model reasonable in design 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 the structural representation of the utility model.
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.
Packed layer 6 adopts the glass rope to fill formation.
Bellows 7 is the aluminium bellows.
The concrete structure of the utility model:
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.
