Description
Technical field
The utility model relates to a kind of polyvinyl chloride cable, and a kind of polyvinyl chloride cable for signal controlling, belongs to field of cable technology specifically.
Background technology
Along with China's sustain economic increases fast, development for line cable industry provides huge market prospects, the temptation that Chinese market is strong, the world is made all sight to be focused on Chinese market, in the decades that reform and opening-up is short, the huge production capacity that Chinese cable manufacturing industry is formed allows the world regard with special esteem.Along with the continuous expansion of the industry sizes such as electric power, communication, track traffic, automobile and shipbuilding, the demand of electric wire is also being increased rapidly, electric wire industry from now on can predicted and also have huge development potentiality.
Cable is under the operational environment of high request, can signal transmission be very important effectively accurately, due to the specific environment in central control system region, circuit is many, magnetic field is large, have noise, external interference seriously often causes wired signal transmission disorderly, do not reach expection result of use, make equipment produce misoperation, even cause casualties and property significant loss.
Utility model content
Technical problem to be solved in the utility model is, for the shortcoming of above prior art, a kind of polyvinyl chloride cable for signal controlling is proposed, under the prerequisite not affecting cable performance, by the improvement to cable internal structure, there is good insulation preformance, the antijamming capability nontoxic Signal transmissions of strong, low halogen feature accurately.
In order to solve the problems of the technologies described above, the utility model provides a kind of polyvinyl chloride cable for signal controlling, comprise conductor, flame-retardant filler and insulating barrier, described conductor comprises signal conductor and power conductor, insulating barrier is coated with outside every root signal core of described signal conductor, coated first screen outside insulating barrier outside every root signal core, and by wrapping lining-layer, all described signal conductors are bundled together; Insulating barrier is coated with outside every root power wire core of described power conductor; all power wire core and described signal conductor are coated togather by secondary shielding layer; and fill fire-retardant filler in gap between described power wire core and signal conductor; wrap up flame-retardant sheath outside described secondary shielding layer thick, the thick outside of described flame-retardant sheath wraps up steel-tape armouring layer and polyvinyl chloride insulation layer successively.
The technical scheme that the utility model limits further is: the aforesaid polyvinyl chloride cable for signal controlling, described wrapping lining-layer is made up of polyethylene and woven wire, described polyethylene is that right-angled intersection mode is wrapped in outside cable core, is wound around tightens in the outside of polyethylene by woven wire.
The aforesaid polyvinyl chloride cable for signal controlling, described flame-retardant sheath thickness is 1.8-3.6mm; Described flame-retardant sheath is made up of polyolefin.
The aforesaid polyvinyl chloride cable for signal controlling, described insulating barrier is the soft sheath of polyether-type TPU resin; Described fire-retardant filler is aluminium hydroxide flame-retardant filler.
Further, the aforesaid polyvinyl chloride cable for signal controlling, described screen is the proof copper-wire braided screen of chemical nickel phosphorus plating.
The beneficial effects of the utility model are: cable of the present utility model has good insulation property, good stability, strong, the low halogen of antijamming capability is nontoxic can adapt to special occasions and adverse circumstances, are specially adapted to control system and are used as instrument and meter signal transmission connection line.The copper wire conductor of multiply for Signal transmissions is set in cable, not oxidizable, conduct electricity very well, soft easy to use; Arrange composite shielding and the duplex sheath Rotating fields of dual-layer optimization in the cable, electromagnetic interference is little each other, and antijamming capability is strong, effectively ensure that the accuracy of cable transmission signal, applicability and fail safe.
