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 industrial shielding fire-proof high-temperature resistant insulated cable.
The utility model is taked following technical scheme to realize: a kind of industrial shielding fire-proof high-temperature resistant insulated cable, and it comprises cable body, conductor, back-fire relief packed layer, inner sheath and oversheath, and the cross section of described cable body is circular configuration; Some conductors are provided with in described cable body; Connected by PVC plastic connecting rod between described conductor; The gap portion of described conductor and PVC plastic connecting rod is provided with back-fire relief packed layer; Described conductor is outside equipped with insulating barrier; Some guide cores are provided with between described insulating barrier and conductor; Gap portion between described insulating barrier and conductor is filled with packed layer; Described insulating barrier closely extrudes one deck screen outward; Armour is extruded with outside described screen; Described armour is extruded with inner sheath and oversheath from inside to outside successively.
Above-mentioned one industrial shielding fire-proof high-temperature resistant insulated cable, described conductor is any one in single copper wire, stranded bare copper wire or stranded tinned copper wire.
Above-mentioned one industrial shielding fire-proof high-temperature resistant insulated cable, described insulating layer material is ethylene propylene rubber insulation material.
Above-mentioned one industrial shielding fire-proof high-temperature resistant insulated cable, the filler material that the gap portion between described insulating barrier and conductor is arranged is ceramic fire guard.
Above-mentioned one industrial shielding fire-proof high-temperature resistant insulated cable, described armour is woven by some strands of stainless steel wires form and be closely extruded in screen surface.
Above-mentioned one industrial shielding fire-proof high-temperature resistant insulated cable, described oversheath and inner sheath adopt any one material in flame retardant plastics, polyvinyl chloride or polysulfide rubber material to be made.
Above-mentioned one industrial shielding fire-proof high-temperature resistant insulated cable, described reinforcing braid material is vinal material, the one of polyethylene terephthalate or mixture.
The utility model has following beneficial effect in sum: this cable has good shielding properties, resist bending performance, conductance is high, also there is high pressure resistant and diamagnetic jamming performance simultaneously, 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.

Embodiment
As shown in Figure 1, a kind of industrial shielding fire-proof high-temperature resistant insulated cable, it comprises cable body 1, conductor 2, back-fire relief packed layer 4, inner sheath 11 and oversheath 12, and the cross section of described cable body 1 is circular configuration; Some conductors 2 are provided with in described cable body 1; Connected by PVC plastic connecting rod 3 between described conductor 2; The gap portion of described conductor 2 and PVC plastic connecting rod 3 is provided with back-fire relief packed layer 4; Described conductor 2 is outside equipped with insulating barrier 7; Some guide cores 5 are provided with between described insulating barrier 7 and conductor 2; Gap portion between described insulating barrier 7 and conductor 2 is filled with packed layer 6; Described insulating barrier 7 is outer closely extrudes one deck screen 8; Armour 9 is extruded with outside described screen 8; Described armour 9 is extruded with inner sheath 11 and oversheath 12 from inside to outside successively.
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 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 PVC plastic connecting rod 3 between described conductor 2, thus effectively add the compact of cable internal structure, make its internal structure more stable; Between described conductor 2 and PVC plastic connecting rod 3 arrange back-fire relief packed layer 4 can effectively protect conductor 2 not damage by high temperature, increase the heat-resisting ability of cable; The filler 6 arranged between described conductor 2 and insulating barrier 7 is ceramic fire guard, it is under the condition of burning, the refractory heat-insulating structure of ceramic-like solid refractory heat-insulating cover is become when meeting high temperature, ceramic silicon materials are under burning condition, meet fire then to crust, reinforced layer is tightly wrapped up, there is good effect of heat insulation; Described guide core 5 is not only conducive to the grounding of cable, and can guarantee the continuity of screen 8; Described insulating barrier 7 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; The screen 8 extruded outside described insulating barrier 7 effectively raises the anti-shielding ability of cable, makes it more stable in use procedure, can not by signal disturbing; The armour 9 extruded outside described screen 8 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 outer reinforcing braid 10 arranged of described armour 9 effectively improves, makes its stretch-proof effect increase, there will not be the situation of fracture; Described inner sheath 11 and oversheath 12 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.
