Description
Technical field
The utility model relates to a kind of cross-linked polyethylene insulated cable, and a kind of resistant to elevated temperatures cross-linked polyethylene insulated cable, 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.
The instructions for use being used in the cable in the power supply engineerings such as steel plant, nuclear power station, chemical industry, gardens lamp decoration is also more and more higher; common cable all has certain heat-resisting quantity; if the operation that cable is long-term in an environment of high temperature; outer layer protective sleeve rubber and structure meeting accelerated ageing; thus cause the insulating barrier of cable breakdown; cause electric leakage, and the useful life of cable is short, so the cable be laid in hot environment generally all needs cable to have certain high-temperature-resistant structure.
Utility model content
Technical problem to be solved in the utility model is, for the shortcoming of above prior art, a kind of resistant to elevated temperatures cross-linked polyethylene insulated cable is proposed, under the prerequisite not affecting cable performance, by the improvement to cable internal structure, have that resistance to elevated temperatures is good, antijamming capability is strong, the nontoxic Signal transmissions of low halogen feature accurately.
In order to solve the problems of the technologies described above, the utility model provides a kind of resistant to elevated temperatures cross-linked polyethylene insulated cable, comprise conductor, flame-retardant filler and insulating barrier, insulating barrier is coated with outside every root core of described conductor, wrap up aluminium strip lapped shielding layer outside the many cores wrapped up by described insulating barrier, in the core gap of aluminium strip lapped shielding layer parcel, be filled with fire-retardant filler; Wrap up wrapping lining-layer and insulating rubber layer outside described aluminium strip lapped shielding layer, outside described insulating rubber layer, wrap up aluminium foil thermal insulation layer, outside described aluminium foil thermal insulation layer, wrap up armour and crosslinked polyetylene insulated layer successively.
The technical scheme that the utility model limits further is: aforesaid resistant to elevated temperatures cross-linked polyethylene insulated cable, 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.
Aforesaid resistant to elevated temperatures cross-linked polyethylene insulated cable, described aluminium foil insulation thickness is 1.0-2.5mm; Described aluminium foil thermal insulation layer surface is provided with ripple fold.
Further, aforesaid resistant to elevated temperatures cross-linked polyethylene insulated cable, described insulating barrier is the soft sheath of polyether-type TPU resin; Described fire-retardant filler is aluminium hydroxide flame-retardant filler.
The beneficial effects of the utility model are: cable of the present utility model has good resistance to elevated temperatures, 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 high-temperature resistant rubber and aluminium foil collet Rotating fields in the cable, good heat-insulation effect each other, antijamming capability is strong, effectively ensure that the accuracy of cable transmission signal, applicability and fail safe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
