The utility model discloses beneficial effect: the utility model discloses it is low temperature resistant, wear -resisting, the stable performance, the wiring is convenient.
Description
Technical field
The utility model belongs to field of cable technology, specifically a kind of low temperature resistant cable being convenient to wiring.
Background technology
At present, along with Chinese society expanding economy, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, the cable such as used in the fields such as aviation, electric power and tunnel, to electric conductivity and the resistance to ag(e)ing of cable, insulation property, low temperature resistant cold-resistant, resistance to wear aspect and security reliability aspect require high all especially, on market, we can see a lot of resistant to elevated temperatures cable, and low temperature resistant cable is rarely found.
Therefore a kind of low temperature resistant cable is needed to use in specific area and field.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of low temperature resistant cable being convenient to wiring, low temperature resistant cold-resistant, easy-to-connect.
The utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of low temperature resistant cable being convenient to wiring, comprise the insulating barrier of conductor and conductor outer cladding, insulating barrier is also coated with the sheath be made up of butyronitrile polyvinyl chloride outward, multiple projection in arc-shaped is provided with at the outer surface of sheath, described conductor forms by many annealed aluminum wire cores are stranded, buries the bracing wire for isolating sheath underground between conductor and sheath along the length direction of cable.
The fire-retardant band of oxygen barrier is also provided with between insulating barrier described in the utility model and sheath.
The beneficial effects of the utility model are:
Compared with prior art, the utility model at least has following advantage and beneficial effect:
1. sheath of the present utility model is made up of butyronitrile polyvinyl chloride, low temperature resistant, acid-alkali-corrosive-resisting, and under psychro-environment, cable performance is stablized, and ageing resistace is given prominence to, long service life;
2. sheath can be cut off formation scarfing by the bracing wire set by the utility model, and then is convenient to peel off sheath, and can not cause the damage to insulated wire cores, thus is conducive to carrying out fast wiring;
3. the projection that the utility model sheath is arranged outward forms sheath protective layer at jacket surface, effectively improves the resistance to wear of whole cable;
4. be provided with the fire-retardant band of oxygen barrier between the utility model insulating barrier and sheath, good flame retardation effect, fire safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1, conductor, 2, insulating barrier, 3, sheath, 4, protruding, 5, bracing wire.
Embodiment
As shown in the figure, a kind of low temperature resistant cable being convenient to wiring, comprise the insulating barrier 2 of conductor 1 and conductor 1 outer cladding, insulating barrier 2 is outer is also coated with the sheath 3 be made up of butyronitrile polyvinyl chloride, multiple projection 4 in arc-shaped is provided with at the outer surface of sheath 3, described conductor 1 forms by many annealed aluminum wire cores are stranded, buries the bracing wire 5 for isolating sheath 2 underground between conductor 1 and sheath 3 along the length direction of cable.
Further, the fire-retardant band of oxygen barrier is also provided with between insulating barrier 2 and sheath 3.
Sheath of the present utility model is made up of butyronitrile polyvinyl chloride, low temperature resistant, acid-alkali-corrosive-resisting, and under psychro-environment, cable performance is stablized, and ageing resistace is given prominence to, long service life.
Sheath can be cut off formation scarfing by the bracing wire arranged, and then is convenient to peel off sheath, and can not cause the damage to insulated wire cores, thus is conducive to carrying out wiring fast.
