Abstract
The utility model discloses an anti-twisting waterproof cable comprising a plurality of conductors, each of which is wrapped by an insulation layer to form an insulation wire core. The plurality of insulation wire 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 sequentially wrapped by a water-blocking tape and an outer sheath, and filling layers are disposed between the cable cores and the inner sheath. The utility model is advantageous in that the inner sheath adopts the design of the braiding in an intersected manner, and the intersected braiding structure is provided with a relatively large stretching space, therefore the anti-twisting ability of the cable can be effectively improved; the design of disposing the water-blocking tape between the inner sheath and the outer sheath, the good waterproof performance can be provided, and the service lifetime of the cable can be prolonged, because the water-blocking tape can be expanded after contacting with the water, and the water can be prevented from being spread along the cable.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of warp resistance water-proof 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, it is inner that water has entered cable, causes insulating barrier to form water tree, the continuous oxidation of water tree, cause the destruction to insulation, so greatly shortened the life-span of cable, and the anti-twist scarce capacity of common cable, being twisted for a long time affects the useful life that also can shorten cable.
The utility model content
The purpose of this utility model provides a kind of warp resistance water-proof cable, and to solve traditional anti-twist scarce capacity of cable in the prior art, water resistance is not good, the problem of being twisted easily after long-time the use and seeping water and affecting 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 water-proof 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: the stranded formation cable core of several insulated wire cores, described cable core is coated with the inner sheath that interlacing consists of, 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 water-proof cable is characterized in that: described conductor is zinc-plated soft copper conductor.
Described a kind of warp resistance water-proof 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, inner sheath adopts the design of interlacing, the interlacing structure has larger extending space, effectively promote the anti-twist ability of cable, adopted the design that waterstop is set between inner sheath and oversheath, after water enters oversheath, the waterstop water-swellable, stop moisture further to spread along cable, have good waterproof action, 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 water-proof 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, the stranded formation cable core of several insulated wire cores, cable core is coated with the inner sheath 3 that interlacing consists of, and is coated with successively waterstop 4 and oversheath 5 outside the inner sheath 3, is provided with packed layer 6 between cable core and the inner sheath 3.Conductor 1 is zinc-plated soft copper conductor, and oversheath 5 adopts silicon rubber to make.
Claims (3)
1. warp resistance water-proof 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: the stranded formation cable core of several insulated wire cores, described cable core is coated with the inner sheath that interlacing consists of, described inner sheath is coated with waterstop and oversheath outward successively, is provided with packed layer between described cable core and the inner sheath.
2. a kind of warp resistance water-proof cable according to claim 1, it is characterized in that: described conductor is zinc-plated soft copper conductor.
