Abstract
The utility model belongs to the field of wires and cables, and particularly relates to an anti-corrosion steel wire armored cable which comprises a cable core, a packing layer, a polyester belting layer and an armoring combination cover layer in sequence from the interior to the exterior. The anti-corrosion steel wire armored cable with a simple structure can not only effctively achieve the effects of delaying water vapor erosion and preventing corrosion after water vapor erosion, but also effectively control the manufacturing cost of the cable and reduce the operation difficulty in cable laying.
Description
Technical field
The utility model belongs to the electric wire field, is specifically related to a kind of anticorrosion steel wire armored cable.
Background technology
Along with the propelling of urbanization and urban planning and construction, cable more options buried-pipe laying mode more in the transformation of urban distribution network and when building.In the part city like the flourishing city of city, island or rivers water system, receive the urban geography environmental impact, bury ground direct-buried cable or cable trough cabling in the part position, cable body a part or whole part receives rainwater to soak phenomenon and often takes place.Behind the cable long-play, because hydrone to the infiltration of sheath internal migration, contacts finally in the inner formation of sheath aqueous vapor, and with armour.To 110kV and the above high-voltage and ultra-high cable that the electrical network main line is used, use plumbous cover of sealing or aluminium cover armour to protect the built-in electrical insulation core to avoid receiving the erosion of aqueous vapor.But for 35kV and following power cable; Generally select steel-tape armouring and polyvinyl chloride oversheath pattern for use; Aqueous vapor when long-time buried-pipe laying is moved corrodes does not have good protective effect, and steel band corrosion behind the long-play loses the effect of armouring and protection.And,, and be not suitable for selecting for use plumbous cover of sealing or aluminium cover armour because use amount is huge huge with laid condition difference to 35kV and following power cable.
The utility model content
In order to overcome the deficiency of prior art, the purpose of the utility model is to provide a kind of anticorrosion steel wire armored cable, delays the erosion of cable aqueous vapor and promote cable to receive aqueous vapor to corrode back armour corrosion-resistant performance.
For addressing the above problem, the technical scheme that the utility model adopted is following:
A kind of anticorrosion steel wire armored cable, it comprises cable core, filler layer, polyester belting layer, armouring associating sheath from inside to outside successively.
In the utility model; Said cable core is made up of copper conductor, conductor shield, insulating barrier, insulation screen, metal screen layer; Wherein conductor shield is coated on the copper conductor; Insulating barrier is set on the conductor shield, insulation screen is set on the insulating barrier, clad metal screen on the insulation screen.
In order to improve the roundness of cable, make things convenient for laying of cable, in the preferred scheme of the utility model, described filler layer is that polypropylene is filled thing layer or polyester fiber filler layer.
In the utility model; What said armouring associating sheath comprised nexine extrudes the LLDPE inner restrictive coating; Extrude the zinc-coated wire armouring is set on the LLDPE inner restrictive coating again; Apply the anticorrosion coat of pitch on the zinc-coated wire armour again, outermost layer is to extrude the high density polyethylene (HDPE) external sheath layer.
Compare prior art; The beneficial effect of the utility model is: the described anticorrosion steel wire armored cable of the utility model is simple in structure; Can effectively reach and delay aqueous vapor and corrode and receive aqueous vapor to corrode back armour corrosion-resistant effect, again the cost made of control cable and the difficulty that reduces the cable laying operation effectively.
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Description of drawings
Fig. 1 is the anticorrosion steel wire armored cable structural representation of the utility model.
Embodiment
As shown in Figure 1, the described anticorrosion steel wire armored cable of the utility model, it comprises cable core, filler layer 6, polyester belting layer 7, armouring associating sheath from inside to outside successively; Wherein, Said cable core is made up of copper conductor 1, conductor shield 2, insulating barrier 3, insulation screen 4, metal screen layer 5; Wherein conductor shield 2 is coated on the copper conductor 1; Insulating barrier 3 is set on the conductor shield 2, insulation screen 4 is set on the insulating barrier 3, clad metal screen 5 on the insulation screen 4; What said armouring associating sheath comprised nexine extrudes LLDPE inner restrictive coating 8; Extrude zinc-coated wire armour 9 is set on the LLDPE inner restrictive coating 8 again; Apply the anticorrosion coat 10 of pitch on the zinc-coated wire armour 9 again, outermost layer is to extrude high density polyethylene (HDPE) external sheath layer 11.
In order to improve the roundness of cable, make things convenient for laying of cable, in the utility model preferred embodiment, described filler layer 6 can select polypropylene to fill a kind of in thing layer or the polyester fiber filler layer.
Above-mentioned execution mode is merely the preferred implementation of the utility model; Can not limit the scope of the utility model protection with this, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement all belong to the utility model scope required for protection.
