Cable body inside is provided with a plurality of conductors, the conductor sets up the one deck protective layer outward, protective layer and conductor constitute the cable core jointly, cable body inside is provided with a plurality of enhancement cores, the cable core sets up the one deck insulating layer outward, the outer closely crowded package one deck shielding layer of insulating layer, the shielding layer is the fine polyester lacing of crowded package one deck glass outward, the fine polyester lacing of glass is crowded package one deck metal armor layer outward, crowded package one deck inner sheath outside the metal armor layer, the outer closely crowded package one deck oversheath of inner sheath. The utility model has the advantages of structural design is reasonable, convenient to use and prevent that corrosive effects is good.

Description

A kind of low smoke and zero halogen Resisting fractre LP blades cable

Technical field

The utility model relates to field of cables, particularly relates to a kind of low smoke and zero halogen Resisting fractre LP blades cable.

Background technology

At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as in industry, the cable used in the field such as electric power and colliery, high all especially to the requirement of the high pressure resistant of cable and Corrosion Protection aspect, very high to the requirement of cable in the field that some are special, but existing cable because of its structural design unreasonable, the needs of people can not be met, this just gives in industry use procedure and brings very large trouble, if the incomplete words that cable possesses, work in these fields and benefit and safety can be affected.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of low smoke and zero halogen Resisting fractre LP blades cable.

The utility model is taked following technical scheme to realize: a kind of low smoke and zero halogen Resisting fractre LP blades cable, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body inside is provided with multiple conductor; Outside described conductor, layer protective layer is set; Described protective layer and conductor form cable core jointly; Described cable body inside is provided with multiple strengthening core; One deck insulating barrier is set outside described cable core; Described insulating barrier closely extrudes one deck screen outward; Layer of glass fiber polyester belt is extruded outside described screen; Layer of metal armour is extruded outside described glass polyester belt; One deck inner sheath is extruded outside described metal armor layers; Described inner sheath closely extrudes one deck oversheath outward.

Above-mentioned a kind of low smoke and zero halogen Resisting fractre LP blades cable, described conductor adopts real core copper core or multiply to press copper core and makes.

Above-mentioned a kind of low smoke and zero halogen Resisting fractre LP blades cable, described insulating barrier, between strengthening core and cable core, gap portion is provided with packed layer.

Above-mentioned a kind of low smoke and zero halogen Resisting fractre LP blades cable, described metal armor layers is wound around by nonmagnetic metal band or wire to make.

Above-mentioned a kind of low smoke and zero halogen Resisting fractre LP blades cable, described oversheath adopts low-smoke halogen-free polyolefin material to make.

The utility model has following beneficial effect in sum: the utility model has the advantages such as reasonable in design, easy to use and anticorrosion ability be good, described oversheath is made up of the corrosion-resistant polyolefine material of the high flame retardant of low smoke and zero halogen, higher temperature can be born, and harmful Substances Pollution environment can not be produced in hot environment, thus make its environmental-protecting performance more excellent, meet present the advocated environmental protection concept of people.

Accompanying drawing explanation

Fig. 1 is the utility model cross-sectional structure schematic diagram;

Wherein: 1, cable body; 2, conductor; 3, protective layer; 4, strengthening core; 5, packed layer; 6, insulating barrier; 7, screen; 8, glass polyester belt; 9, metal armor layers; 10, inner sheath; 11, oversheath.

Embodiment

As shown in Figure 1, a kind of low smoke and zero halogen Resisting fractre LP blades cable, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 6, screen 7 and oversheath 11, and described cable body 1 inside is provided with multiple conductor 2; Outside described conductor 2, layer protective layer 3 is set; Described protective layer 3 and conductor 2 form cable core jointly; Described cable body 1 inside is provided with multiple strengthening core 4; One deck insulating barrier 6 is set outside described cable core; Described insulating barrier 6 is outer closely extrudes one deck screen 7; Layer of glass fiber polyester belt 8 is extruded outside described screen 7; Layer of metal armour 9 is extruded outside described glass polyester belt 8; One deck inner sheath 10 is extruded outside described metal armor layers 9; Described inner sheath 10 is outer closely extrudes one deck oversheath 11.

Described conductor 2 adopts real core copper core or multiply to press copper core and makes, and not only substantially increases the operating efficiency of cable, also makes its work more stable, and described conductor 2 structure is easy to processing; The strengthening core 4 that described cable body 1 inside is arranged improves the elastic strength of cable body 1, enables cable bear larger pressure; Described glass polyester belt 8 can make cable normally work under high temperature or high and cold situation, and electric property is stablized, and ageing resistace is given prominence to; Described metal armor layers 9 is wound around by nonmagnetic metal band or wire to make, and not only effectively eliminate the eddy current problem that magnetic material armouring produces, also effectively can improve the structural stability of cable body 1, the ability making it bear high pressure and distortion power is stronger; Described oversheath 11 is made up of the corrosion-resistant polyolefine material of the high flame retardant of low smoke and zero halogen, higher temperature can be born, and harmful Substances Pollution environment can not be produced in hot environment, thus make its environmental-protecting performance more excellent, meet present the advocated environmental protection concept of people.

The above is embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
