Abstract
The present utility model discloses an intrinsic safety waterproof control cable. The cable comprises multiple groups of wire cores, each group of wire cores is formed by intertwisting two or three strands of conductors, a polrvinyl chloride insulation layer is wrapped outside each strand of conductors, a non hygroscopic wrapping belt and a plastic-aluminum composite membrane double layer separated shielding layer are successively wrapped outside each group of wire cores, a polyvinyl chloride wrapping belt, a seamless metal sleeve, a plastic-aluminum composite membrane total shielding layer and an oversheath are successively wrapped outside the multiple groups of wire cores wrapped by the separated shielding layer, and hygroscopic materials are filled inside the wrapping belt. Water-blocking yarns with good hygroscopic performance are filled into the cable, waterproof performance of the conductors is effectively guaranteed, the cable is long in service life, has excellent oil resistant performance and corrosion resistant performance, and is suitable for ports, 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 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 useful life is short, and in use, need to regularly overhaul so not only waste of manpower, increase cost, also have simultaneously very large potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of essential safety waterproof control cables, and is relatively poor with the water resistance that solves cable in the prior art, contacting the problem that has potential safety hazard with water for a long time.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of essential safety 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 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 waterproof control cables is characterized in that: described oversheath adopts silastic material to make.
Described a kind of essential safety waterproof control cables is characterized in that: described seamless metal cover adopts metal bellows to make.
Described a kind of essential safety waterproof control cables 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, has effectively guaranteed the water resistance of conductor, and the utility model long service life, and 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 outer polyvinyl chloride twining package tape 5, seamless metal cover 6, the total screen 7 of aluminum-plastic composite membrane and the oversheath 8 of being coated with successively after the coating sub-shield 4 is filled with hygroscopic materials 9 in the twining package tape 5.
Oversheath 8 adopts silastic material to make.Seamless metal cover 6 adopts metal bellows to make.The hygroscopic materials 9 of filling is water blocking yarn.
