Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of shield type stretch-proof power cable.
Background technology
At present, electric wire is extensively applied to industrial production, communications and transportation, architectural engineering and facility, even comprise the high-end field of space and ocean, capital uses cable, along with socioeconomic development, cable kind constantly update and perfect, output is also continuing to increase, just because cable is in the application of different field, people also improve its requirement thereupon, existing cable can not meet the needs of industry because of material or structural problem, common cable is easy to the interference being subject to outer signals, make the distorted signals of cable transmission, very large loss is brought to enterprise.
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 shield type stretch-proof power cable.
The utility model is taked following technical scheme to realize: a kind of shield type stretch-proof power cable, and it comprises cable body, and described cable body comprises conductor, insulating barrier and oversheath, and described cable body inside is provided with many conductors; Described conductor is outside equipped with the first screen; Described first screen and conductor form cable core jointly; Described cable core is outside equipped with insulating barrier; Between described insulating barrier and cable core, gap portion is provided with filler; Described insulating barrier closely extrudes one deck secondary shielding layer outward; Described secondary shielding layer is extruded with steel wire armor layer and inner sheath from inside to outside successively; Described steel wire armor layer inside is provided with many carbon fiber composite core rods; Described inner sheath closely extrudes one deck oversheath outward.
Above-mentioned a kind of shield type stretch-proof power cable, described conductor is any one in single copper wire, stranded bare copper wire or stranded tinned copper wire.
Above-mentioned a kind of shield type stretch-proof power cable, described insulating layer material is ethylene propylene rubber insulation material.
Above-mentioned a kind of shield type stretch-proof power cable, the filler material that the gap portion between described insulating barrier and conductor is arranged is ceramic SiClx fire guard.
Above-mentioned a kind of shield type stretch-proof power cable, described steel wire armor layer is that stainless steel wire braiding forms, and is square grid shape structure.
Above-mentioned a kind of shield type stretch-proof power cable, described oversheath and inner sheath adopt any one material in flame retardant plastics, polyvinyl chloride or polysulfide rubber material to be made.
The utility model has following beneficial effect in sum: the utility model cable has the advantages such as reasonable in design, advantages of good shielding performance and long service life, described insulating barrier adopts ethylene propylene rubber insulation material to make, because ethylene-propylene rubber has the characteristic such as excellent weather, resistance to ozone, heat-resisting, acid and alkali-resistance, resistance to steam, thus the stability of cable is improved, and surface of insulating layer coefficient of friction is large, cable is when uninterrupted bending, also can not there is relative displacement in insulating barrier part, thus ensure the normal output of electric property.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, the first screen; 4, filler; 5, insulating barrier; 6, secondary shielding layer; 7, steel wire armor layer; 8, carbon fiber composite core rod; 9, inner sheath; 10, oversheath.
Embodiment
As shown in Figure 1, a kind of shield type stretch-proof power cable, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 5 and oversheath 10, and described cable body 1 inside is provided with many conductors 2; Described conductor 2 is outside equipped with the first screen 3; Described first screen 3 and conductor 2 form cable core jointly; Described cable core is outside equipped with insulating barrier 5; Between described insulating barrier 5 and cable core, gap portion is provided with filler 4; Described insulating barrier 5 is outer closely extrudes one deck secondary shielding layer 6; Described secondary shielding layer 6 is extruded with steel wire armor layer 7 and inner sheath 9 from inside to outside successively; Described steel wire armor layer 7 inside is provided with many carbon fiber composite core rods 8; Described inner sheath 9 is outer closely extrudes one deck oversheath 10.
The conductor 2 arranged in described cable body 1 is any one in single copper wire, stranded bare copper wire or stranded tinned copper wire, not only substantially increases the operating efficiency of cable, also makes its work more stable; Described filler 4 is ceramic SiClx fire guard, effectively adds the compact of cable internal structure, makes its internal structure more stable; First screen 3 of described conductor 2 outer wrapping and the outer secondary shielding layer 6 arranged of insulating barrier 5 effectively can improve the shielding properties of cable, prevent it to be subject to the interference of outer signals, substantially increase job stability; Described insulating barrier 5 adopts ethylene propylene rubber insulation material to make, because ethylene-propylene rubber has the characteristic such as excellent weather, resistance to ozone, heat-resisting, acid and alkali-resistance, resistance to steam, thus the stability of cable is improved, and insulating barrier 5 skin-friction coefficient is large, cable is when uninterrupted bending, also can not there is relative displacement in insulating barrier, thus ensure the normal output of electric property; The steel wire armor layer 7 extruded outside described secondary shielding layer 6 is woven by some strands of stainless steel wires to form, the useful life of cable can be made than general cable long service life, and can higher electric current be transmitted, bear larger overload, even if cable uses the long period, no power runs, and also can not reduce insulation property because of the material moisture absorption; The intensity of the cable body 1 that the carbon fiber composite core rod 8 that described steel wire armor layer 7 inside is arranged effectively improves, makes its stretch-proof effect increase, there will not be the situation of fracture; Described inner sheath 9 and oversheath 10 adopt any one material in smoke halogen-free flame-proof plastic for low, polyvinyl chloride or polysulfide rubber material to be made, not only high temperature resistant, and also can not pernicious gas be produced under burning condition, prevent it from causing people's life danger at fire release pernicious gas.
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.
