Abstract
The utility model discloses a kind of Novel anti-explosion cable, comprise cable core, cable core forms by several wire core is stranded; Described core is made up of insulated wire cores and the first carbon fiber knit layer be arranged on outside insulated wire cores; Sheath is extruded, wrapped belt again after sheath outer surface copper powder rubber mixture layers outside cable core; Be outside equipped with the second carbon fiber knit layer cable core outermost layer at belting layer and extrude oversheath.The features such as the utility model has good bending property, and shock resistance, explosion-proof performance are good, and cable weight is light, mounting and installation is simple.
Description
Technical field
The utility model relates to electric wire field, refers in particular to a kind of Novel anti-explosion cable.
Background technology
The place that anti-explosion cable has explosion risk at some is widely applied, such as in warehouse, chemical enterprise, gas station, gas station, oil play etc. the place high to security requirement, all need to adopt anti-explosion cable to meet the high request of these places to fail safe.For preventing because the storm shock wave caused that explodes damages cable, and the electromagnetic interference between circuit and surrounding devices, the existing main inside that adopts adds circular bursting diaphragm, and the shielding of wire armoring, proof copper-wire braided meets the demands.
2, prior art Problems existing and shortcoming
Anti-explosion cable is that cable inside is provided with circular bursting diaphragm, and mainly wire armoring, copper wire armored realize, and makes cable to destroy under the effect of external force, but adopts the softness, the bendability that this configuration reduces cable; Bursting diaphragm add the weight penalty that membership makes cable itself, add on the one hand the difficulty of mounting and installation, make cable can only be suitable for land on the other hand and use, be not suitable for using on naval vessel.
Utility model content
Technical problem to be solved in the utility model is to overcome prior art defect, provides a kind of good bending property, and shock resistance, explosion-proof performance are good, and cable weight is light, the simple anti-explosion cable of mounting and installation.
In order to solve the problems of the technologies described above, the utility model provides a kind of Novel anti-explosion cable, comprises cable core, and cable core forms by several wire core is stranded; Described core is made up of insulated wire cores and the first carbon fiber knit layer be arranged on outside insulated wire cores; Sheath is extruded, wrapped belting layer again after sheath outer surface copper powder rubber mixture layers outside cable core; Be outside equipped with the second carbon fiber knit layer cable core outermost layer at belting layer and extrude oversheath.
Further improvement, described insulated wire cores is made up of conductor and the insulating barrier be extruded in outside conductor.
The beneficial effects of the utility model are:
1, in the structure choice of conductor, select multiply thin copper wire lay configuration, maximum filament diameter selects the 6th kind of soft copper conductor in GB/T3956-2008, and adopts advanced multiple drawing machine, ensures that string diameter deviation range controls at ± 0.01mm;
2, insulated wire cores weaves one deck carbon fiber resin composite material outward.Carbon fiber resin composite material has well high temperature resistant, shock resistance, can effectively protect insulated wire cores;
3, extrude one deck copper powder rubber composition outside sheath, copper powder rubber composition be by weight ratio 10%---the copper powder of 25% is added in semi-conductive rubber material uniformly.Be extruded in outside sheath by copper powder rubber composition, form layer of metal rubber screen, replace common metal woven shield, shield effectiveness is identical with metal knitted shielding, but improves the softness of cable;
4, two-layer carbon fiber resin composite material is woven outward, as armour at lapping layer.Carbon fiber resin composite material proportion is less than 1/4 of steel, and its tensile strength is 7-9 times of steel, and tensile modulus of elasticity is also higher than steel.Explosion-proof performance, withstand voltage properties, shock resistance are all better than zinc-coated wire, the superior function of carbon fiber resin composite material, effectively can replace zinc-coated wire, and reduce the weight of cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of Novel anti-explosion cable described in the utility model, comprises cable core, and cable core forms by several wire core is stranded; Described core is made up of insulated wire cores and the first carbon fiber knit layer 3 be arranged on outside insulated wire cores; Described insulated wire cores is made up of conductor 1 and the insulating barrier 2 be extruded in outside conductor 1; Sheath 4 is extruded, wrapped belting layer 6 again after sheath 4 outer surface copper powder rubber mixture layers 5 outside cable core; Be outside equipped with the second carbon fiber knit layer 7 at belting layer 6, cable core outermost layer extrudes oversheath 8.
Utility model works principle or the course of work:
The deficiencies such as softness, the bending property of improving existing anti-explosion cable are poor, shock resistance, explosion-proof performance are poor, and cable weight is heavy, mounting and installation is difficult, mainly realize from following aspect:
1, in the structure choice of conductor, select multiply thin copper wire lay configuration, maximum filament diameter selects the 6th kind of soft copper conductor in GB/T3956-2008, and adopts advanced multiple drawing machine, ensures that string diameter deviation range controls at ± 0.01mm.
2, insulated wire cores weaves one deck carbon fiber resin composite material outward.Carbon fiber resin composite material has well high temperature resistant, shock resistance, can effectively protect insulated wire cores;
3, extrude one deck copper powder rubber composition outside sheath, copper powder rubber composition be by weight ratio 10%---the copper powder of 25% is added in semi-conductive rubber material uniformly.Be extruded in outside sheath by copper powder rubber composition, form layer of metal rubber screen, replace common metal woven shield, shield effectiveness is identical with metal knitted shielding, but improves the softness of cable;
4, two-layer carbon fiber resin composite material is woven outward, as armour at lapping layer; Carbon fiber resin composite material proportion is less than 1/4 of steel, and its tensile strength is 7-9 times of steel, and tensile modulus of elasticity is also higher than steel.Explosion-proof performance, withstand voltage properties, shock resistance are all better than zinc-coated wire, the superior function of carbon fiber resin composite material, effectively can replace zinc-coated wire, and reduce the weight of cable.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from the utility model principle, these improvement also should be considered as protection range of the present utility model.
