Abstract
The utility mode discloses an anti-twisting waterproof tensile flexible cable comprising a plurality of conductors, each of which is wrapped by an insulation layer to form an insulation wire core. Each of the insulation wire cores is wrapped by a slipping layer, and a plurality of insulation wire cores and the reinforced steel cores are intertwisted together to form cable cores, which are wrapped by an inner sheath formed by the braiding in an intersected manner. The inner sheath is wrapped by a water-blocking tape and an outer sheath, and filling layers are disposed among the cable cores and the inner sheath. The utility model is advantageous in that the structure is simple, the anti-twisting ability, the tensile ability, and the waterproof performance are good, the good slipping performance among various insulation wire cores is good, the bending can be facilitated, the deformation is not easy to occur, and the service lifetime of the cable can be effectively prolonged.
Description
Technical field
The utility model relates to the electric wire field, is specially a kind of warp resistance waterproof tensile flexible cable.
Background technology
Along with the fast development of power industry, urban construction, all trades and professions are more and more higher to the requirement of cable, in use, will avoid not only that cable is mechanically damaged, insulation harm, ageing of insulation are rotten etc., also will avoid humidified insulation.Cable sometimes need to be laid in ground or the place of water is arranged, because the permeability of cable sheath material, perhaps cable cover(ing) is by mechanical damage, and it is inner that water has entered cable, cause insulating barrier to form water tree, the continuous oxidation of water tree causes the destruction to insulation, has so greatly shortened the life-span of cable, and the warp resistance ability of common cable and resistance to tension are not enough, be difficult for bending, be subjected to distortion, stretching and bending to affect easy distortion, cause shorten the useful life of cable.
The utility model content
The purpose of this utility model provides a kind of warp resistance waterproof tensile flexible cable, not enough to solve the anti-twist ability of cable traditional in the prior art and resistance to tension, be difficult for bending, water resistance is not good, the problem of being twisted easily, stretch, bending after long-time the use and seep water and affect and cause cable to shorten useful life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of warp resistance waterproof tensile flexible cable, include the array conductor, every group of conductor all is coated with insulating barrier outward and consists of insulated wire cores, it is characterized in that: every eradication edge core is coated with glide lamella, several insulated wire cores and the stranded rear formation cable core of reinforcement steel core, described cable core is coated with the inner sheath that interlacing consists of, and described inner sheath is coated with waterstop and oversheath outward successively, is provided with packed layer between described cable core and the inner sheath.
Described a kind of warp resistance waterproof tensile flexible cable is characterized in that: described conductor is zinc-plated soft copper conductor.
Described a kind of warp resistance waterproof tensile flexible cable is characterized in that: described glide lamella is the macromolecule material film layer of low-friction coefficient.
Described a kind of warp resistance waterproof tensile flexible cable is characterized in that: described oversheath adopts silicon rubber to make.
The beneficial effects of the utility model are:
The utility model is simple in structure, and inner sheath adopts the design of interlacing, and the interlacing structure has larger extending space, has effectively promoted the anti-twist ability of cable; Employing, conveniently bends so that have good slipping property between each insulated wire cores in the design of insulated wire cores outer cladding glide lamella, and not yielding; Adopt the design stranded with strengthening steel core of several insulated wire cores, effectively promoted the resistance to tension of cable; Employing arranges the design of waterstop between inner sheath and oversheath, after water entered oversheath, the waterstop water-swellable stoped moisture further to spread along cable, has good waterproof action, has effectively prolonged the useful life of cable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of warp resistance waterproof tensile flexible cable, include array conductor 1, every group of conductor 1 is outer all to be coated with insulating barrier 2 and to consist of insulated wire cores, every eradication edge core is coated with glide lamella 3, several insulated wire cores and reinforcement steel core 4 stranded rear formation cable cores, and cable core is coated with the inner sheath 5 that interlacing consists of, be coated with successively waterstop 6 and oversheath 7 outside the inner sheath 5, be provided with packed layer 8 between cable core and the inner sheath 5.
Conductor 1 is zinc-plated soft copper conductor, and glide lamella 3 is the macromolecule material film layer of low-friction coefficient, and oversheath 7 adopts silicon rubber to make.
