Abstract
The utility model discloses a movable oil-resistant rubber sleeve cable which is characterized in that each insulated cable core is formed by wrapping a polyester tape (2) outside a stranded copper conductor (1) and sequentially pressing and wrapping a rubber insulation layer (3) and wrapping a heat-resistant and oil-resistant teflon film wrapping tape (4) outside the polyester tape (2); a plurality of insulated cable cores are stranded together to form a cable core; and an oil-resistant cushion layer (5) is wrapped and an oil-resistant nitrile rubber sheath (6) is pressed and wrapped outside the cable core in sequence. The movable oil-resistant rubber sleeve cable has excellent oil resistance, thereby prolonging the service life of the cable and reducing the probability of accidents. The oil-resistant and heat-resistant teflon film can be used for preventing crude oil from penetrating into an insulated layer of the cable, thereby protecting the insulated layer of the cable from being damaged by oil gas; and the oil-resistant cushion layer can be used for preventing the oil gas from further penetrating into the inner layer after the cable sheath is damaged and cannot generate any chemical reaction with the cable sheath and the insulated layer.
Description
Technical field
The utility model relates to a kind of Plastic-sheathed Cable, and particularly mobile oilproof cabtyre cable, belong to technical field of electric wires and cables.
Background technology
Plastic-sheathed Cable is widely used in various electric equipments, household appliance for example, motor machine, the movable power wire of electrical device and utensil.Can use under indoor or outdoor environment condition simultaneously.Move and be commonly used in the occasions such as harbour, harbour, mine with Plastic-sheathed Cable, be mainly used in mobile device and be connected with the power supply of control cubicle.
Oil resistant cable is applicable to the industrial and mining enterprises such as metallurgy, oil, chemical industry and power plant; under hot conditions and in adverse circumstances, (as acid, alkali, oily cryogenic conditions) is as the connecting line of various electrical equipment, instrument and automatics, under 450/750 volt of ac rated voltage and following control, monitoring and protective circuit luggage occasion.Along with industrial expansion, more and more general to the demand of oil resistant cable, and every year is in rising trend because of the poor accident that causes of cable oil resistance.
The utility model content
Goal of the invention of the present utility model is to provide a kind of high performance mobile oilproof cabtyre cable, thereby improves cable quality, extends the useful life of cable, reduces because of the poor accident rate that causes of cable oil resistance.
The utility model realizes that goal of the invention is achieved through the following technical solutions:
Mobile oilproof cabtyre cable, its design feature is, by the outer wrapped polyester belt of twisted copper conductors, and extrude successively rubber insulation outside polyester belt, wrapped heat-resisting oil resistant polytetrafluoroethylene film band consists of insulated wire cores, described insulated wire cores has many, the edge cores that thoroughly do away with twist together the formation cable core more, described cable core outward more successively wrapped oil resistant bed course, extrude the oil resistant butadiene-acrylonitrile rubber sheath.
The utility model design feature also is:
Described oil resistant bed course is comprised of nylon fiber layer, polytetrafluoroethylene film layer and oil resistant rubberised layer from inside to outside successively.
Described oil resistant bed course is two-layer.
Described polyester belt is the PET material, and described rubber insulation is the ethylene-propylene rubber material.
The utility model beneficial effect is embodied in:
The utility model adopts at the wrapped heat-resisting oil resistant film band in ethylene propylene rubber insulated core outside; heat-resisting oil resistant film adopts polytetrafluoroethylene film; contain fluorine atom in the molecular structure of polytetrafluoroethylene film; its chemical stability, resistance to medium and osmotic-pressure-tolerant are all fine; prevent that crude oil from immersing the insulating barrier of cable; thereby the protection cable insulation is avoided the infringement of oil gas, guarantees the insulation property of cable.
The utility model adopts outside cable core and is provided with the oil resistant bed course, and the oil resistant bed course mainly is comprised of nylon fiber framework material, polytetrafluoroethylene film and oil resistant rubberised layer; Polytetrafluoroethylene film belongs to barrier layer, prevents the oil gas infiltration, and the nylon fiber skeleton belongs to increases layer, and its effect is the intensity that guarantees band, and the oil resistant rubberised layer has good heat aging property and oil resistance.After the oil resistant bed course can guarantee that cable cover(ing) is destroyed, can stop that oil gas further permeates to internal layer.And with cable cover(ing) and insulation, any chemical reaction does not occur.
Description of drawings
Fig. 1 is the utility model construction of cable schematic diagram.
Number in the figure: 1 twisted copper conductors, 2 polyester belts, 3 rubber insulations, 4 heat-resisting oil resistant polytetrafluoroethylene film bands, 5 oil resistant bed courses, 6 oil resistant butadiene-acrylonitrile rubber sheaths.
Technical solutions of the utility model are described further by embodiment below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1, cable comprises soft twisted copper conductors 1, polyester belt 2, rubber insulation 3, heat-resisting oil resistant polytetrafluoroethylene film band 4, oil resistant bed course 5, oil resistant butadiene-acrylonitrile rubber sheath 6 from inside to outside.
in concrete enforcement, conductor adopts annealed copper conductor lay configuration, work at the twisted copper conductors 1 wrapped polyester belt 2 in outside the effect of tightening, the rubber insulation 3 of ethylene-propylene rubber material is extruded in outside polyester belt 2 by the catenary suspension type continuous vulcanization continuous extrusion curing line, three second the third wrapped heat-resisting oil resistant polytetrafluoroethylene film bands 4 of insulated wire cores outside difference, then twist together and consist of cable core and wrapped two-layer with the nylon fiber layer, the oil resistant bed course 5 that polytetrafluoroethylene film layer and oil resistant rubberised layer form, extrude oil resistant butadiene-acrylonitrile rubber sheath 6 by the catenary suspension type continuous vulcanization continuous extrusion curing line at last on oil resistant bed course 5.Heat-resisting oil resistant polytetrafluoroethylene film band 4 base-materials are comprised of acrylonitrile-butadiene rubber and chlorosulfonated polyethylene rubber, and it has oil resistance and ageing-resistant performance preferably.The utility model cable has excellent oil resistance, thereby extends the useful life of cable, the generation of minimizing accident.The heat-resisting oil resistant thin layer of polytetrafluoroethylene can prevent that crude oil from immersing the insulating barrier of cable, thereby the protection cable insulation is avoided the infringement of oil gas, after the oil resistant bed course can guarantee that cable cover(ing) is destroyed, can stop that oil gas further permeates to internal layer.And with cable cover(ing) and insulation, any chemical reaction does not occur.
