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 fire-resistant stretch-proof armoured cable.
The utility model is taked following technical scheme to realize: a kind of fire-resistant stretch-proof armoured 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; Many described conductors extrude formation cable core jointly; Described cable body inside is provided with many cable cores; Be connected by rubber skeleton between described cable core; The gap portion formed between described cable core is provided with light unit; Described cable core closely extrudes a layer insulating outward; Gap portion between described insulating barrier and cable core is provided with packed layer; Described insulating barrier closely extrudes one deck screen outward; Described screen is extruded with reinforced layer, aluminium alloy lock armo layer and flame retardant coating from inside to outside successively; Described flame retardant coating closely extrudes one deck oversheath outward.
The fire-resistant stretch-proof armoured cable of above-mentioned one, described conductor adopts real core copper core or multiply to press copper core and makes, and its cross sectional shape is circular or sector structure.
The fire-resistant stretch-proof armoured cable of above-mentioned one, described flame retardant coating is carbon fiber tape or ceramic fibre strip.
The fire-resistant stretch-proof armoured cable of above-mentioned one, the light unit that described conductor and connecting rod center are arranged is monomode fiber or multimode fiber.
The fire-resistant stretch-proof armoured cable of above-mentioned one, described oversheath adopts any one material in smoke halogen-free flame-proof plastic for low, polyvinyl chloride or polysulfide rubber material to be made.
The utility model has following beneficial effect in sum: this cable has good shielding properties, resist bending performance, Nai Gao and the advantage such as high pressure resistant, described conductor adopts real core copper core or multiply to press copper core and makes, its cross sectional shape is circular or sector structure, 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, there is during use certain flexibility and bendability, facilitate 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, rubber skeleton; 4, light unit; 5, packed layer; 6, insulating barrier; 7, screen; 8, reinforced layer; 9, aluminium alloy lock armo layer; 10, flame retardant coating; 11, oversheath.
Embodiment
As shown in Figure 1, a kind of fire-resistant stretch-proof armoured 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 many conductors 2; Many described conductors 2 extrude formation cable core jointly; Described cable body 1 inside is provided with many cable cores; Be connected by rubber skeleton 3 between described cable core; The gap portion formed between described cable core is provided with light unit 4; Described cable core closely extrudes a layer insulating 6 outward; Gap portion between described insulating barrier 6 and cable core is provided with packed layer 5; Described insulating barrier 6 is outer closely extrudes one deck screen 7; Described screen 7 is extruded with reinforced layer 8, aluminium alloy lock armo layer 9 and flame retardant coating 10 from inside to outside successively; Described flame retardant coating 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, its cross sectional shape is circular or sector structure, 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, has certain flexibility and bendability during use, facilitates the laying of workpeople; The rubber skeleton 3 connected between described conductor 2 not only plays the effect of attached cable, cable body 1 internal structure also can be made comparatively compact, make its work more stable; The light unit 4 that described conductor 2 inside is arranged is monomode fiber or multimode fiber, not only makes the speed that diffuses information of cable faster, and is not easy to be subject to extraneous interference, the use of cable can be made more reliable and more stable, make the capacity of Information Communication larger; The packed layer 5 arranged between described insulating barrier 6 and conductor 2 can improve the heat-resisting ability of cable greatly, makes its more resistance to burning, can not damage by high temperature; Described insulating barrier 6 effectively can improve the insulation property of cable body 1, makes its work more stable; The screen 7 extruded outside described insulating barrier 6 makes cable body 1 effectively can prevent signal disturbing, makes in its signals transmission more stable; The outer reinforced layer 8 arranged of described screen 7 makes it have good resistance to aromatic solvent, soda acid chemicals and oil based solvent corrosive power, higher anti ageing property, less insulation dielectric loss, thus reaches etch-proof performance; Described aluminium alloy lock armo layer 9 can make the useful life of cable than general cable long service life, and can higher electric current be transmitted, bear larger overload, and aluminium alloy lock armo barrier layer 9 has good damp proof insulation and prevents the effect of chemical corrosion, even if cable uses the long period, no power runs, and also can not reduce insulation property because of the material moisture absorption; Described flame retardant coating 10 is carbon fiber tape or ceramic fibre strip, and cable can be made to use in high temperature environments, and can be fire-retardant so that protection safe power supply after catching fire; Described oversheath 11 adopts any one material in smoke halogen-free flame-proof plastic for low, polyvinyl chloride or polysulfide rubber material to be made, 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.
