Abstract
Disclosed is an anti-pulling waterproof control cable for intrinsic safety, comprising multiple sets of wire core composed of two or three strands of intertwisted conductors, wherein each strand of conductor is wrapped by a polrvinyl chloride insulating layer; each set of wire core is sequentially wrapped by a non-hygroscopic wrapping tape and a plastic-aluminum composite membrane double-layer sub-shielding layer; multiple sets of wire cores wrapped by sub-shielding layer and multiple reinforcing steel wires are twisted to form a cable core; the cable core is sequentially wrapped by a polyvinyl chloride wrapping tape, a seamless metal sheath, a plastic-aluminum composite membrane total shielding layer, and an outer sheath; and the winding tape is filled with hygroscopic material. The anti-pulling waterproof control cable of the utility model is filled with water-blocking yarn with excellent hygroscopicity, thereby effectively ensuring the waterproof performance of the conductor. The employment of the reinforcing steel wire effectively improves the anti-pulling performance of the cable. The anti-pulling waterproof control cable of the utility model features long service lifetime, and excellent oil resistance and decay resistance. The anti-pulling waterproof control cable of the utility model is applicable to harbors, hydropower stations, reservoirs, tunnels, and other places.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of essential safety tension waterproof control cables.
Background technology
Development along with science and technology, the transmission network of various electric power, information is very extensive, the applied environment of cable is very complicated, wherein just comprise the places such as harbour, harbour, hydroelectric station, reservoir, tunnel, usually to touch water, even at underwater work, just the waterproof requirement to cable is very high for this.The cable that uses now generally has the formations such as conductor, insulating barrier, screen, restrictive coating, and its water resistance is very weak, and tensile property is not good, useful life is short, and in use, needs overhauling of timing, so not only waste of manpower increases cost, also has simultaneously very large potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of essential safety with tension waterproof control cables, and is relatively poor with the water resistance and the tensile property that solve cable in the prior art, for a long time with operational environment that water contacts under have the problem of potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of essential safety tension waterproof control cables, it is characterized in that: include the array core, every group of core is by two strands or three strands of conductors are stranded consists of, per share conductor is coated with the polyvinyl chloride insulation layer, every group of core is coated with non-hygroscopic band and aluminum-plastic composite membrane double-layer shielding layer outward successively, array core after the described coating sub-shield and the stranded formation cable core of several reinforcement steel wire, described cable core is coated with polyvinyl chloride twining package tape, seamless metal cover, the total screen of aluminum-plastic composite membrane and oversheath outward successively, is filled with hygroscopic materials in the described twining package tape.
Described a kind of essential safety tension waterproof control cables is characterized in that: described oversheath adopts nitrile rubber to make.
Described a kind of essential safety tension waterproof control cables is characterized in that: described seamless metal cover adopts metal bellows to make.
Described a kind of essential safety tension waterproof control cables, it is characterized in that: the hygroscopic materials of described filling is water blocking yarn.
The beneficial effects of the utility model are:
The utility model is filled with preferably water blocking yarn of moisture absorption, effectively guaranteed the water resistance of conductor, adopt the design of stranded reinforcement steel wire, effectively promoted the tensile property of cable, and the utility model long service life, oil resistance, fine corrosion resistance are fit to and the places such as harbour, harbour, hydroelectric station, reservoir, tunnel.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model includes array core 1, every group of core 1 is by two strands or three strands of conductors are stranded consists of, per share conductor is coated with polyvinyl chloride insulation layer 2, every group of core 1 outer non-hygroscopic band 3 and aluminum-plastic composite membrane double-layer shielding layer 4 of being coated with successively, array core 1 and several reinforcement steel wire 10 stranded formation cable cores after the coating sub-shield 4, cable core is coated with polyvinyl chloride twining package tape 5, seamless metal cover 6, the total screen 7 of aluminum-plastic composite membrane and oversheath 8 outward successively, is filled with hygroscopic materials 9 in the twining package tape 5.
Oversheath 8 adopts nitrile rubber to make.Seamless metal cover 6 adopts metal bellows to make.The hygroscopic materials 9 of filling is water blocking yarn.
