Abstract
The utility model discloses an intrinsic-safety control cable which comprises a plurality of sets of cores. Each set of cores comprise two or three stranded conductors, a polyvinyl chloride insulation layer is coated outside each conductor, a non-hygroscopicity packing belt and an aluminum and plastic film double-layer separated screen layer are coated outside each set of cores sequentially, and polyvinyl chloride wrapping belts, aluminum and plastic film major screen layers, polyester belts and outer sheaths are sequentially coated outside the sets of cores coated with the separated screen layers. Hygroscopic materials are filled in the wrapping belts. Highly-hygroscopic waterproof yarn is filled in the intrinsic-safety control cable, and accordingly waterproofing performance of the conductors is guaranteed effectively. In addition, the intrinsic-safety control cable is long in service life, excellent in grease resistance and corrosion resistance and applicable to places of ports, wharfs, hydroelectric stations, reservoirs, tunnels and the like.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of essential safety and uses control cable.
Background technology
Continuous development along with science and technology; Various electric power, transmission of Information network are very extensive; The applied environment of cable is very complicated, wherein just comprises places such as harbour, harbour, hydroelectric station, reservoir, tunnel, usually will touch water; Even at underwater work, just the waterproof requirement to cable is very high for this.The cable that uses now generally has formations such as conductor, insulating barrier, screen, restrictive coating, its water resistance very a little less than, useful life is short; And in use, need regularly overhaul so not only waste of manpower; Increase cost, also have very big potential safety hazard simultaneously.
The utility model content
The purpose of the utility model provides a kind of essential safety and uses control cable, 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 scheme that the utility model adopts is:
A kind of essential safety is used control cable; It is characterized in that: include the array core; Every group of core is by two strands or three strands of conductors are stranded constitutes, and per share conductor is coated with the polyvinyl chloride insulation layer, and 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 said coating sub-shield is coated with polyvinyl chloride twining package tape, the total screen of aluminum-plastic composite membrane, polyester belt and oversheath outward successively, is filled with hygroscopic materials in the said twining package tape.
Described a kind of essential safety is used control cable, it is characterized in that: said oversheath adopts silastic material to process.
Described a kind of essential safety is used control cable, it is characterized in that: the hygroscopic materials of said filling is a water blocking yarn.
The beneficial effect of the utility model is:
The utility model is filled with moisture absorption water blocking yarn preferably, has guaranteed the water resistance of conductor effectively, and the utility model long service life, and oil resistance, fine corrosion resistance are fit to and places such as harbour, harbour, hydroelectric station, reservoir, tunnel.
Description of drawings
Fig. 1 is the structural representation of the 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 constitutes, and 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; Coat the outer total screen of polyvinyl chloride twining package tape 5, aluminum-plastic composite membrane 6, polyester belt 7 and the oversheath 8 of being coated with successively of array core 1 after the sub-shield 4, be filled with hygroscopic materials 9 in the twining package tape.
Oversheath 8 adopts silastic material to process.The hygroscopic materials 9 of filling is a water blocking yarn.
Claims (3)
