Abstract
The utility model relates to an extra soft flat cable used for winding 6/10 kv ethylene propylene insulated butyronitrile sheath. An insulating layer made of extra soft ethylene propylene insulated mixture is wrapped uniformly on single or multiple extra soft tinned copper conductor (s) with uniform elongation. Two layers and a half of conductive tape isolation layer I are wound on insulating layer uniformly; an extra soft copper wire braided layer is woven on isolation layer I. An isolation layer II is wrapped uniformly on braided layer to form core, an outer sheath formed by extra soft PVC - butyronitrile composite mixture is wrapped on periphery of core. With good softness and excellent tensile strength, the utility model is applicable to frequent bending and reciprocating situation, and has the advantages of good electrical performance, long service life and high safety.
Description
Affiliated technical field
The utility model relates to a kind of 6/10kV second third insulation butyronitrile sheath reels with special soft flat cable, belongs to technical field of electric wires and cables.
Background technology
At present, the line cable industry Move Volumes is around the common rubber sleeve flexible cable of the many employings of class cable, cable in running because of being subjected to multiple mechanical stress effects such as frequent bending, stretching, easily cause break core, decreasing insulating and braid copper wire of conductor to poke insulating barrier and make phenomenons such as insulation breakdown, cause equipment to stop operating, had a strong impact on user's use, caused very big loss to the user.
Summary of the invention
The purpose of this utility model provides a kind of good electric property, flexibility is good, pull resistance is strong, resistance to bend(ing) can be reeled with special soft flat cable by the 6/10kV second third insulation butyronitrile sheath superior, long service life.
The technical solution of the utility model is: a kind of 6/10kV second third insulation butyronitrile sheath is reeled with special soft flat cable, and it is made up of copper conductor, insulating barrier, separator 1, braid, separator II and oversheath.On single or many zinc-plated soft copper conductors, evenly extrude a layer insulating.The wrapped two-layer separator I that constitutes by semi-conductive tape on insulating barrier.Braiding one deck tincopper fuse wire braided armor on separator I.Wrapped one deck extrudes oversheath by the separator II that semi-conductive tape constitutes on separator II on braid.
Described conductor and braid all adopt the special soft and uniform tin-coated copper conductor of percentage elongation.
Described insulating barrier adopts special soft second third insulation compound.
Described oversheath adopts special soft pvc-butyronitrile compound elastomer compound.
The beneficial effects of the utility model are: owing to adopted the special soft and uniform tin-coated copper conductor of percentage elongation, improved the anti-performance that circumnutates of conductor greatly.Owing between insulating barrier and braid, between braid and oversheath, all be provided with separator, increased the relative slippage between core and the restrictive coating, thereby improved the anti-twisting property of cable.Owing to adopted special preferably soft second third insulation compound of insulation property as insulating barrier, make the highest long-term work temperature of this cable bring up to 30 ℃, and Insulation Material hardness be less than 50 Shao Shi A.Owing to adopt special soft pvc-butyronitrile compound oversheath, make protective cover material hardness less than 70 Shao Shi A, thereby improved the flexibility of cable greatly, and this sheath has wear-resistant, anti-aging, tear-proof, corrosion-resistant, have bigger tensile strength.Implementation by above measure, make this product have good flexibility, splendid pull resistance and superior resistance to bend(ing), the occasion that is fit to frequent bending and moves back and forth, compared with similar products, can prolong 2～3 times useful life, and improved electric property, useful life and the fail safe of cable greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, copper conductor, 2, insulating barrier, 3, separator I, 4, braid, 5, separator II, 6, oversheath.
Embodiment
It is that example illustrates execution mode of the present utility model that present embodiment is reeled with three-core cable in the special soft flat cable with the 6/10kV second third insulation butyronitrile sheath.As shown in the figure: all extrude the insulating barrier 2 that one deck is made by soft second third insulation compound of spy on the soft and uniform tin-coated copper conductor 1 of percentage elongation at three Gents.The separator I3 that evenly wrapped two-layer semi-conductive tape constitutes on each insulating barrier.The braiding braid 4 that one deck is soft by the spy and the uniform copper wire of percentage elongation constitutes on separator I.Even wrapped one deck semi-conductive tape separator II5 forms three cores on braid.After being arranged side by side, three cores extrude one deck again in its periphery by oversheath 6 that special soft pvc-butyronitrile compound elastomer compound constitutes.
Claims (1)
- A kind of 6/10kV second third insulation butyronitrile sheath is reeled with special soft flat cable, it is characterized in that: it is to extrude the insulating barrier that one deck is made by soft second third insulation compound of spy at single or many Gents on the soft and uniform tin-coated copper conductor of percentage elongation, even wrapped two-layer semi-conductive tape separator I on insulating barrier, the braiding braid that one deck is soft by the spy and the uniform copper wire of percentage elongation constitutes on separator I, even wrapped one deck semi-conductive tape separator II forms core on braid, extrudes one deck in above-mentioned core periphery by oversheath that special soft pvc-butyronitrile compound elastomer compound constitutes.
