Abstract
The utility model discloses a power cable. The power cable comprises conductors, insulation wire cores and an outer sheath layer. Butyronitrile compound insulating layers are extruded outside the conductors so as to form the insulation wire cores. The three insulation wire cores are combined and then a polyurethane belting layer wraps the three insulation wire cores. A metal shielding layer is braided outside the belting layer so as to form a wire core group. A steel wire rope separating layer and an outer mantle layer wrap the four wire core groups after being intertwisted. Four control wire cores are arranged among the four wire cores. Each control wire core is formed through wrapping the polyurethane belting layer by two guide cores. Each guide core is formed through extruding the butyronityile compound insulating layer outside the conductors. Tensile filling ropes are arranged in gaps among cable cores. The power cable is safe and reliable. The service life of the conductor is long and installation is simple. The power cable can adapt to various kinds of working environments.
Description
technical field
The utility model relates to a kind of power cable, belongs to technical field of electric wires and cables.
background technology
Mobile device dynamical system, along with the raising of equipment performance and specification requirement, has more property to equipment dynamic with the requirement of power cable, has tension, softness, resistance to bending, resistance to frequent movement and long service life, safety, the feature such as reliable simultaneously.The power cable of using as mobile device system power requires the characteristics such as tension, softness, resistance to bending, resistance to frequent movement, wants safety, reliable, long service life, safety guarantee to have relatively high expectations simultaneously.But existing conventional common cable can not meet this requirement.
utility model content
The utility model object is to provide the characteristics such as a kind of tension, softness, resistance to bending, resistance to frequent movement, electric performance stablity, wants safety, reliable, conductor long service life, simple installation simultaneously, can adapt to the power cable of multiple different operating environment.
Scheme of the present utility model is as follows: a kind of power cable, comprise conductor, insulated wire cores, external sheath layer, described conductor extrudes butyronitrile compound insulating barrier outward and forms insulated wire cores, wrapped polyurethane belting layer after three insulated wire cores combinations, the outer braided metal screen of described belting layer forms core group, four stranded rear wrapped steel wire rope separators of core group and jacket layer, between four described cores, also arrange four and control core, described control core is led the wrapped polyurethane belting layer of core by two and is formed, the described core of leading forms by extruded butyronitrile compound insulating barrier outward by conductor, cable core gap is provided with to do draws gasket for packing.
Further, described conductor twisted wire pitch is that between 10-16 times, conductor structure meets the 5th kind of conductor standard in GB/T 3956.
Further, the sectional area of described conductor is 15～85mm
2.
Further, described external sheath layer adopts butyronitrile composite materials.
The utility model conductor adopts multiply copper free wire to be woven at many levels on the regular stranded steel wire rope of multiply of tension, the flexibility of conductor body and resistance to bending, tensile property are good, improve the safety and reliability in use procedure, extended the useful life of conductor.In the utility model, insulating barrier, steel wire rope separator and sheath all adopt butyronitrile composite materials, and it has pull resistance, resistance to wear, flexibility and the weatherability of wide range.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of power cable, comprise conductor, insulated wire cores, external sheath layer, the outer butyronitrile compound insulating barrier 2 that extrudes of described conductor 1 forms insulated wire cores, wrapped polyurethane belting layer 3 after three insulated wire cores combinations, the outer braided metal screen 4 of described belting layer 3 forms core group, four stranded rear wrapped steel wire rope separators 5 of core group and jacket layer 6, between four described cores, also arrange four and control core 7, described control core is led the wrapped polyurethane belting layer of core by two and is formed, and the described core of leading forms by extruded butyronitrile compound insulating barrier outward by conductor; Cable core gap is provided with to do draws gasket for packing.
Described conductor 1 twisted wire pitch is that between 10-16 times, conductor is tied 1 structure and met the 5th kind of conductor standard in GB/T 3956.The sectional area of described conductor 1 is 15～85mm
2.Described external sheath layer 6 adopts butyronitrile composite materials.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and revise; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
