Abstract
The invention discloses a multi-core cross linked polyethylene insulated armor halogen-free low-smoke inflaming retarding power cable. The power cable comprises a plurality of sets of wire cores, wrapping tape, an inner sheath, an armor and an outer sheath. Each wire core comprises a plurality of conductors, an inner semi-conductive shield, an insulating layer, an outer semi-conductive shield and a copper strip shield, wherein the inner semi-conductive shield, the insulating layer, the outer semi-conductive shield and the copper strip shield are sequentially wrapped outside the conductors. The cable cores and filling materials are twisted together to form a cable core. The cable core is wrapped with the wrapping tape. The inner sheath, the armor and the outer sheath are arranged outside the wrapping tape in sequence. The armor power cable can enhance the mechanical strength of the cable, improve the erosion resistance, be laid conveniently, enhance the strength of extension and compressive strength and other mechanical protection capacity, and prolong the service life. The armor power cable is free of releasing halogen gas, low in smoke concentration and low in gas corrosion under the condition that the power cable is burned. The armor power cable is high in safety, excellent in mechanical performance and high in chemical resistance.
Description
Technical field
The invention belongs to cable technology field, be specifically related to the crosslinked polyetylene insulated armored halogen-free low smoke power cable of a kind of multicore.
Background technology
Cross-linked polyethylene insulated cable has significantly improved the performance of polyvinyl chloride cable.The long-term permission working temperature of cross-linked polyethylene insulated cable can reach 90 ℃.At 130 ℃ of temperature to keep elastic stage.Cross-linked polyethylene insulated cable weight/power ratio is light, and diameter is little, and mounting and installation is convenient, and attachment tab is simple, and is used widely.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; And most of electric wire can produce a large amount of hypertoxic dense smoke when burning, cause great Loss of Life and property, and bring very large difficulty to rescue work, particularly at the environment of space relative closure, when used in the environment such as indoor, tunnel, can bring hidden danger to Environmental security.Therefore need to improve its structure, to increase its tensile strength, compression strength, increase the service life, low smoke and zero halogen during burning, further expands its scope of application.
Summary of the invention
The object of the present invention is to provide the crosslinked polyetylene insulated armored halogen-free low smoke power cable of a kind of multicore.
Object of the present invention can be achieved through the following technical solutions:
The crosslinked polyetylene insulated armored halogen-free low smoke power cable of a kind of multicore, it comprises many group cores, band, inner sheath, armouring and oversheath, described core comprises many conductors and is wrapped in successively interior semi-conductive screen, insulating barrier, semi-conductive shield outside and the copper strip shielding outside many described conductors, described core is stranded rear formation cable core together with packing material, the outer wrapped band of described cable core, described band is provided with inner sheath, armouring and oversheath outward successively.
The crosslinked polyetylene insulated armored halogen-free low smoke power cable of above-mentioned multicore, the armouring described in it is steel-tape armouring or LWA light wire armoured.
The crosslinked polyetylene insulated armored halogen-free low smoke power cable of above-mentioned multicore, the conductor described in it is copper.
The crosslinked polyetylene insulated armored halogen-free low smoke power cable of above-mentioned multicore, described in it, the material of insulating barrier is crosslinked polyethylene.
The crosslinked polyetylene insulated armored halogen-free low smoke power cable of above-mentioned multicore, described in it, the material of inner sheath and oversheath is low-smoke halogen-free polyolefin.
Beneficial effect of the present invention:
For preventing that power cable with cross-linked polyethylene insulation is subject to mechanical damage, forms crosslinked polyetylene insulated armoured power cable and install steel first protective layer additional at skin.Can increase the mechanical strength of cable; improve erosion prevention; it is convenient to lay; can also strengthen the mechanical protections such as tensile strength, compression strength and increase the service life, this armoured power cable has certain external force resistance performance, can also watch out for mouse to bait; be unlikely to see through armouring and cause electric power transfer problem; it is large that the bending radius of armouring is wanted, and armour can ground connection, protection cable.And this power cable, 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.
