Abstract
The utility model provides an explosion-proof cable including a middle cable core, a filler filling in gaps of the cable core, and a wrapping layer, an inner liner, a linkage armor layer which sequentially wrap the outside of the cable core, and an oversheath extruding at the outermost layer of the cable core. The cable core is twisted by three power wire cores, one control cable core and two signal cable cores. A further modified technical scheme is that the cable core is twisted by three power wire cores, one control wire core and two signal wire cores. By adopting the linkage armor layer, the explosion-proof cable is high in mechanical strength and good in shielding performance, not only a mechanical explosion-proof function resisting shock waves of storms is achieved, but also a good anti-electromagnetic interference effect is achieved, and the shield effect is distinctly.
Description
Technical field
The utility model relates to special cable field, specifically a kind of anti-explosion cable.
Background technology
Now there is no the anti-explosion cable that directly can lay.For preventing because of the storm shock wave that blast causes, cable being damaged, and the electromagnetic interference between circuit and surrounding devices, now main employing installed steel pipe, in steel pipe, penetrate the method for flame retardant cable, can effectively solve the injury that the shock wave that produces because of blast causes cable, and can not tackle secondary injury after blast: as burning and high temperature.Lasting high temperature can damage the cable in steel pipe, thereby has influence on the normal use of equipment.
Adopt the method for common anti-explosion cable, explosion-proof effect is good, at high temperature can continuous service, but it generally has steel belt layer or steel wire floor, and cable weight is heavier, installs and uses very inconvenience.For needs, use and can not use compared with the occasion of light weight cable, as naval vessel, weight increase not only can affect headway, and affects naval vessel storage goods and materials amount.
Utility model content
The utility model provides a kind of anti-electromagnetic interference strong anti-explosion cable, and not only fire resistance is good, and lightweight.
A kind of anti-explosion cable described in the utility model, cable core in the middle of comprising, filler is filled in cable core gap, be coated on successively belting layer, inner covering, the chain armour outside cable core and be extruded in the outermost oversheath of cable core, described cable core is by three power cores, a control cable core and two stranded forming of signal cable core.Further improve, described cable core is three power cores, a control core, two stranded forming of signal core.
Further improve, described power core consists of middle tinned copper conductor and the first insulating barrier of being extruded in outside tinned copper conductor.
Further improve, described control cable core is controlled core pair twists by two pairs and is formed, and described control core consists of middle control line core conductor and the second insulating barrier, the inner sheath that are extruded in outside control line core conductor.
Further improve, described signal cable core is formed by two signal core pair twists, and described signal core is by middle holding wire core conductor, and the 3rd insulating barrier, the inner sheath that are extruded in outside holding wire core conductor form.
Further improve, described inner covering is low-smoke halide-free fireproof composite polyolefine material; Described oversheath is low-smoke halide-free fireproof composite polyolefine material.
Further improve, the first described insulating barrier, the second insulating barrier, the 3rd insulating barrier adopt ethylene propylene rubber insulation material again.
The beneficial effects of the utility model are: this cable machinery intensity is high, and advantages of good shielding performance not only has the mechanical explosion function of resisting storm shock wave, and have the effect of good anti-electromagnetic interference, and shield effectiveness is outstanding.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
A kind of anti-explosion cable of the utility model, cable core in the middle of comprising, filler 3 is filled in cable core gap, be coated on successively belting layer 4, low smoke halogen-free flame-retardant polyolefin inner covering 5, the chain armour 6 outside cable core and be extruded in the outermost low smoke halogen-free flame-retardant polyolefin oversheath 7 of cable core, described cable core is by three power cores, a control cable core and two stranded forming of signal cable core.
Power core described above consists of middle tinned copper conductor 1 and ethylene-propylene rubber the first insulating barrier 2 of being extruded in outside tinned copper conductor 1; Described control cable core is controlled core pair twists by two pairs and is formed, and described control core consists of middle control line core conductor 8 and exhausted the second insulating barrier 9 of ethylene-propylene rubber, the inner sheath 10 that are extruded in outside control line core conductor 8; Described signal cable core is formed by two signal core pair twists, and described signal core is by middle holding wire core conductor 13, and exhausted the 3rd insulating barrier 12 of ethylene-propylene rubber, the inner sheath 11 that are extruded in outside holding wire core conductor 13 form.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
