Description

A kind of elasticity stretch-proof cable
Technical field
The utility model relates to field of cables, particularly relates to a kind of elasticity stretch-proof cable.
Background technology
At present, along with the development of science and technology, the fields such as industry are also at rapid advances, what bring is the increase of cable consumption thereupon, cable normally has several or several groups of wires often to organize the cable of at least two stranded similar ropes, often organize mutually insulated between wire, and be often twisted into around a center, whole outside is surrounded by the cover layer of high-insulation, the kind of cable has a lot, the environment for use that can be applied in fields different in a lot of field is different, therefore different requirements is also had to cable, existing cable is in use often because the stressed excessive cable body internal structure that causes in the external world is damaged, be easy to break down when its work, a lot of inconvenience is brought to staff.
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 elasticity stretch-proof cable.
The utility model is taked following technical scheme to realize: a kind of elasticity stretch-proof 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 many conductors; Described conductors cross is circular configuration; Described conductor closely extrudes a layer insulating outward; Gap portion between described insulating barrier and conductor is provided with packed layer; Described insulating barrier closely extrudes one deck screen outward; Described screen is extruded with metal tape armour layer and glass polyester belt from inside to outside successively; Described glass polyester belt closely extrudes one deck inner sheath outward; One deck oversheath is extruded outside described inner sheath; Described metal tape armour layer inside is provided with many guide cores.
Above-mentioned a kind of elasticity stretch-proof cable, described conductor adopts real core copper core or multiply to press copper core and makes.
Above-mentioned a kind of elasticity stretch-proof cable, the packed layer that the gap portion between described insulating barrier and conductor is arranged is made up of non-net polypropylene tearing material of opening.
Above-mentioned a kind of elasticity stretch-proof cable, described conductor radially vibrational power flow is inner in cable body.
Above-mentioned a kind of elasticity stretch-proof cable, described insulating barrier is that Ceramic silicon rubber material is made.
The utility model has following beneficial effect in sum: a kind of industrial high temperature resistant moistureproof power cable of the utility model has the advantages such as reasonable in design, high temperature resistant and long service life, and described conductor adopts real core copper core or multiply to press copper core makes, not only substantially increase the operating efficiency of cable, also make its work more stable, and described conductor structure is easy to processing, making length is unrestricted, has certain flexibility and bendability during use, facilitates the laying of workpeople.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, packed layer; 4, insulating barrier; 5, screen; 6, metal tape armour layer; 7, glass polyester belt; 8, inner sheath; 9, oversheath; 10, guide core.
Embodiment
As shown in Figure 1, a kind of elasticity stretch-proof cable, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 4, screen 5 and oversheath 9, and described cable body 1 inside is provided with many conductors 2; Described conductor 2 cross section is circular configuration; Described conductor 2 is outer closely extrudes a layer insulating 4; Gap portion between described insulating barrier 4 and conductor 2 is provided with packed layer 3; Described insulating barrier 4 is outer closely extrudes one deck screen 5; Described screen 5 is extruded with metal tape armour layer 6 and glass polyester belt 7 from inside to outside successively; Described glass polyester belt 7 is outer closely extrudes one deck inner sheath 8; One deck oversheath 9 is extruded outside described inner sheath 8; Described metal tape armour layer 6 inside is provided with many guide cores 10.
The conductor 2 arranged in described cable body 1 adopts real core copper core or multiply to press copper core and makes, not only substantially increase the operating efficiency of cable, also make its work more stable, and described conductor 2 structure is easy to processing, making length is unrestricted, there is during use certain flexibility and bendability, facilitate the laying of workpeople; The packed layer 3 arranged between described conductor 2 and insulating barrier 4 has certain elasticity, when cable bends by external force, ensure that cable has bending and indeformable performance to a certain extent, cable can use under the environment of alternating bending, improves the environmental suitability of cable; Described insulating barrier 4 is made for Ceramic silicon rubber material, thus greatly can improve the insulation property of cable body 1, makes its work more stable, the conductor 2 of effective protection; The screen 5 extruded outside described insulating barrier 4, effectively can add the useful life of cable and water-fast and weatherability; Described metal tape armour layer 6 adopts stainless steel wire to weave and forms, and its count is no less than 88%, the shielding properties of cable can not only be improved further, also insulating barrier 4 and the conductor 2 of cable inside can be protected, greatly reduce the moisture absorption of cable and the performance of oxidation, ensure the long-term shield effectiveness efficiently of cable; The outer glass polyester belt closely extruded of described screen 5 can use under high temperature and high and cold environment, and electric property is stablized, and ageing resistace is given prominence to, convenient mobile, can meet the demand of people for a long time; The guide core 10 that described metal tape armour layer 6 inside is arranged effectively can improve the ability of the transmission current of cable afterwards, effectively raises operating efficiency; Described inner sheath 8 and oversheath 9 have fire-retardant fireproof characteristic, and during fire, cable is nonflammable, and can stop burning after flame spread the expansion with disaster, the smog produced during cable fire is also very thin, is conducive to the evacuation of personnel and the carrying out of fire-fighting work.
The above is the utility model embodiment, 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.
