Abstract
The invention discloses a fireproof low-smoke halogen-free armoured power cable which comprises a plurality of wire cores, a halogen-free wrapping tape, a lining layer, an armoured layer and a sheath. Each wire core is composed of a conductor, a fireproof isolating layer and an insulating layer, wherein the fireproof isolating layer and the insulating layer sequentially wrap the conductor. The wire cores are twisted to form a cable core, the cable core is wrapped by the halogen-free wrapping layer, and the lining layer, the armoured layer and the sheath are sequentially arranged outside the halogen-free wrapping tape. When the fireproof low-smoke halogen-free armoured power cable is burned, no halogen gas is released. Thus, the fireproof low-smoke halogen-free armoured power cable is low in the smoke concentration, low in gas corrosion, high in using safety, excellent in mechanical performance and strong in chemical resistance. Furthermore, the armoured layer enables the power cable to have certain external force resistance, and the power cable is prevented from being baited by mice and can bear mechanical external force.
Description
Technical field
The invention belongs to cable technology field, be specifically related to a kind of fire-resistant low smoke and zero halogen armoured power cable.
Background technology
Traditional PVC(polyvinyl chloride) electric wire, when fire occurs PVC mixture after being heated, easily decompose overflow have in a large number severe toxicity, HCL(hydrogen chloride is corrosive) gas, and produce a large amount of hypertoxic dense smoke, cause great Loss of Life and property, and bring very large difficulty (as Korea S's subway big fire) to rescue work, particularly at the environment of space relative closure, when used in the environment such as raceway groove or tunnel, can bring hidden danger to Environmental security.Cross-linked polyethylene insulated cable has significantly improved the performance of polyvinyl chloride cable.But power cable with cross-linked polyethylene insulation is easily etched or is subject to mechanical damage in use, by mouse, baited or lost by worm ant moth, thereby affecting its electric power transfer.Therefore need to provide a kind of and both can the in the situation that of burning, not discharge Halogen gas, smokescope is low, gas attack is low, can increase its tensile strength, compression strength again, the novel cable increasing the service life.
Summary of the invention
The object of the present invention is to provide a kind of fire-resistant low smoke and zero halogen armoured power cable.
Object of the present invention can be achieved through the following technical solutions:
A kind of fire-resistant low smoke and zero halogen armoured power cable, it comprises many cores, Halogen twining package tape, inner covering, armour and sheath, described core by conductor and the fire-resistant separator and the insulating barrier that are wrapped in successively outside conductor form, and the stranded rear formation cable core of described core, described cable core is surrounded with Halogen twining package tape outward, and described Halogen twining package tape is provided with inner covering, armour and sheath outward successively.
Described core is 2 ~ 5.
Described conductor is copper or aluminium, and the material of described insulating barrier is crosslinked polyethylene.
The material of described sheath is low-smoke halogen-free polyolefin.
Described armouring is steel-tape armouring or LWA light wire armoured.
Beneficial effect of the present invention:
The fire-resistant low smoke and zero halogen armoured power cable of the present invention's design, the in the situation that of burning, does not discharge Halogen gas, and smokescope is low, and gas attack is low.Usage safety performance is high, and mechanical performance is excellent, chemical-resistance is strong.And armature of cable makes cable have certain external force resistance performance, can also watch out for mouse and bait, and can bear mechanical external force.
Accompanying drawing explanation
Fig. 1 is fire-resistant low smoke and zero halogen armoured power cable structure chart.
Embodiment
As shown in Figure 1, a kind of fire-resistant low smoke and zero halogen armoured power cable, it comprises many cores, Halogen twining package tape 4, inner covering 6, armour 7 and sheath 5, described core is comprised of conductor 1 and the fire-resistant separator 2 and the insulating barrier 3 that are wrapped in successively outside conductor 1, and the stranded rear formation cable core of described core, described cable core is surrounded with Halogen twining package tape 4 outward, outer inner covering 6, armour 7 and the sheath 5 of being provided with successively of described Halogen twining package tape 4.Described core is 4.
Described conductor 1 is copper or aluminium, and the material of described insulating barrier 3 is crosslinked polyethylene.
The material of described sheath 5 is low-smoke halogen-free polyolefin.
Described armouring 8 is steel-tape armouring or LWA light wire armoured.
The low smoke and zero halogen armoured power cable of the present invention design is for there being fire-resistant requirement and the cable cigarette that cable discharges when catching fire few, in the lower raceway groove of gas attack performance, lays, and can bear in the electric line of mechanical external force.Usage safety performance is high, can bear mechanical external force.And armature of cable makes cable have certain external force resistance performance, can also watch out for mouse and bait, and can bear mechanical external force.
