Abstract
The utility model discloses a fireproof low-smoke halogen-free armored power cable which comprises a plurality of wire cores, a halogen-free winding band, an inner lining layer, an armor layer and a sheath, wherein the wire cores comprise conductors and a fireproof isolating layer and an insulating layer sequentially wrapped outside the conductors, the wire cores are twisted to form a cable core which is wrapped by the halogen-free winding band, and an inner lining layer, the armor layer and the sheath are sequentially arranged outside the halogen-free winding band. The fireproof low-smoke halogen-free armored power cable when burned does not release halogen-containing gases, and is low in smog concentration and gas corrosivity. The fireproof low-smoke halogen-free armored power cable is high in use safety, and excellent in mechanical property and chemically-resistant performance. The armored layer provides the cable with the capability to resist external forces, prevents biting by a mouse and bears outer mechanical forces.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of fire-resistant low smoke and zero halogen armoured power cable.
Background technology
Traditional PVC(polyvinyl chloride) electric wire, the PVC mixture is overflowed in the easy decomposition in the back that is heated when fire takes place severe toxicity in a large number, HCL(hydrogen chloride is corrosive) gas, and produce a large amount of hypertoxic dense smoke, cause great life and property loss, and bring very big difficulty (as Korea S's subway big fire) to rescue work, particularly at the environment of space relative closure, when using 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 etched or is subjected to mechanical damage in use easily, is baited by mouse or by the moth erosion of worm ant, thereby influences its electric power transfer.Therefore need provide a kind of and both can under the situation of burning, not discharge Halogen gas, smokescope is low, gas attack is low, can increase its tensile strength, compression strength again, the novel cable that increases the service life.
The utility model content
The purpose of this utility model is to provide a kind of fire-resistant low smoke and zero halogen armoured power cable.
The purpose of this utility model 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 is by conductor and be wrapped in conductor outer fire-resistant separator and insulating barrier successively and form, and the stranded back of described core forms cable core, described cable core is surrounded with the 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 armour is steel-tape armouring or LWA light wire armoured.
The beneficial effects of the utility model:
The fire-resistant low smoke and zero halogen armoured power cable of the utility model design does not discharge Halogen gas under the situation of burning, smokescope is low, and gas attack is low.The usage safety performance height, mechanical performance excellence, chemical-resistance are strong.And armature of cable makes cable that certain external force resistance performance be arranged, and can also watch out for mouse and bait, and can bear mechanical external force.
Description of drawings
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 by conductor 1 and be wrapped in conductor 1 outer fire-resistant separator 2 and insulating barrier 3 successively and form, and the stranded back of described core forms cable core, described cable core is surrounded with Halogen twining package tape 4 outward, described Halogen twining package tape 4 outer inner covering 6, armour 7 and the sheaths 5 of being provided with successively.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 armour 7 is steel-tape armouring or LWA light wire armoured.
The low smoke and zero halogen armoured power cable of the utility model design is used for having fire-resistant requirement and the cable cigarette that cable discharges when catching fire few, lays in the lower raceway groove of gas attack performance, can bear in the electric line of mechanical external force.The usage safety performance height can bear mechanical external force.And armature of cable makes cable that certain external force resistance performance be arranged, and can also watch out for mouse and bait, and can bear mechanical external force.
