Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of water-blocking moistureproof power 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, but existing cable can not play moistureproof effect because its structural design is unreasonable, when aqueous vapor invades cable inside, the serious consequences such as system is short-circuited can be made, a lot of unsafe factor is brought to the use in later stage.
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 water-blocking moistureproof power cable.
The utility model is taked following technical scheme to realize: a kind of water-blocking moistureproof power cable, and it comprises cable body, conductor, insulating barrier, screen and oversheath, and the cross section of described cable body is circular configuration; Described cable body inside is provided with some conductors; A layer insulating is extruded outside described conductor; One deck screen is extruded outside described insulating barrier; Described conductor, insulating barrier and screen form cable core jointly; Described cable body inside is provided with two cable cores; Connected by plastic cement skeleton between described cable core; Described cable core closely extrudes one deck waterstop outward; Gap portion between described waterstop and cable core is filled with gasket for packing; Described waterstop is extruded with epoxy resin layer, armour and inner sheath from inside to outside successively; Described inner sheath closely extrudes one deck oversheath outward.
Above-mentioned a kind of water-blocking moistureproof power cable, described conductor adopts real core copper core or multiply to press copper core and makes.
Above-mentioned a kind of water-blocking moistureproof power cable, described armour is woven by stainless steel wire to form, and be square grid shape structure.
Above-mentioned a kind of water-blocking moistureproof power cable, the stainless steel wire count of described armour is no less than 90%.
Above-mentioned a kind of water-blocking moistureproof power cable, described epoxy resin layer adopts plastic-blasting mode to process formation, and the thickness of epoxy resin layer is 5mm.
Above-mentioned a kind of water-blocking moistureproof power cable, described oversheath and inner sheath adopt to be made up of the butyronitrile material of the organic silicon ribbon adding mica, anticorrisive agent and antioxidant
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, insulating barrier; 4, screen; 5, plastic cement skeleton; 6, gasket for packing; 7, waterstop; 8, epoxy resin layer; 9, armour; 10, inner sheath; 11, oversheath.
Embodiment
As shown in Figure 1, a kind of water-blocking moistureproof power cable, it comprises cable body 1, conductor 2, insulating barrier 3, screen 4 and oversheath 11, and the cross section of described cable body 1 is circular configuration; Described cable body 1 inside is provided with some conductors 2; A layer insulating 3 is extruded outside described conductor 2; One deck screen 4 is extruded outside described insulating barrier 3; Described conductor 2, insulating barrier 3 and screen 4 form cable core jointly; Described cable body 1 inside is provided with two cable cores; Connected by plastic cement skeleton 5 between described cable core; Described cable core closely extrudes one deck waterstop 7 outward; Gap portion between described waterstop 7 and cable core is filled with gasket for packing 6; Described waterstop 7 is extruded with epoxy resin layer 8, armour 9 and inner sheath 11 from inside to outside successively; Described inner sheath 10 is outer closely extrudes one deck oversheath 11.
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; Connected by plastic cement skeleton 5 between described conductor 2, thus effectively add the compact of cable internal structure, make its internal structure more stable; The insulating barrier 3 of the outer setting of described conductor 2 and screen 4 improve the insulation property of cable, also effectively improve the shielding properties of cable, avoid the phenomenon producing insulation breakdown, reduce the impact of outside electromagnetic interference on electric field simultaneously; Described gasket for packing 6 can improve the intensity of cable body 1 greatly, can resist bending, uses convenient; It is inner that described waterstop 7 can effectively prevent moisture in air from entering conductor 2, makes it make moist, thus occur the situation of short circuit, substantially increases the stability that cable uses; Described epoxy resin layer 8 fully can improve cable water resistance in a humid environment, extends the useful life of cable; Described armour is that stainless steel wire braiding forms, and 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; The inner sheath 10 closely extruded outside described armour 9 and oversheath 11 adopt to be made up of the butyronitrile material of the organic silicon ribbon adding mica, anticorrisive agent and antioxidant, thus there is fire-retardant fireproof characteristic, 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.
