Abstract
The utility model discloses a kind of withstand voltage anti-fracture cable, comprise some cable cores, described cable core periphery is equipped with insulating barrier, also comprise the PVC oversheath in flat, described insulating barrier periphery is spirally wound with horizontal winding layer, and the periphery of described horizontal winding layer is provided with filler, is extruded in described PVC oversheath outside filler, described cable core is the stranded rope-lay strand of many conductor wires, is provided with polyethylene fibre silk thread between described filler and PVC oversheath.The utility model makes cable when causing friction because of interface pressure by arranging filler, prior to cable core conductor distortion, effectively alleviates cable core conductor by extraneous frictional force; PVC oversheath adopts flat simultaneously, guarantees that cable softness is good, for laying installation is provided convenience; Between filler and PVC oversheath, be provided with polyethylene fibre silk thread, the intensity of whole cable monomer increased, not easy fracture, useful life increases.
Description
Technical field
The utility model relates to a kind of withstand voltage anti-fracture cable.
Background technology
Cable is seen everywhere in the electrical apparatus, and cable is normally formed by several or several groups of wire strandings, and often organize mutually insulated between wire, and be often twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Wire is as part most important in cable, and it not only will meet electrical characteristic requirements, also must have certain intensity and toughness, and still can keep above-mentioned performance in high and low temperature environment.At present, still have some transmission pressures to be all bare aluminium wire, easily there is icing phenomenon in sleety weather conductive line surfaces in the winter time, under extreme case, even can exceed the ability to bear of wire, cause wire fracture when ice and snow is thicker; Cable lay or install and alternating bending time, conductor because of interface pressure cause friction thus cause conductor wear and tear broken string, very serious security incident can be caused.
Utility model content
The purpose of this utility model overcomes weak point of the prior art, provides the withstand voltage anti-fracture cable of a kind of intensity and good toughness.
The purpose of this utility model is achieved through the following technical solutions:
A kind of withstand voltage anti-fracture cable, comprise some cable cores, described cable core periphery is equipped with insulating barrier, it is characterized in that: also comprise the PVC oversheath in flat, described insulating barrier periphery is spirally wound with horizontal winding layer, and the periphery of described horizontal winding layer is provided with filler, is extruded in described PVC oversheath outside filler, described cable core is the stranded rope-lay strand of many conductor wires, is provided with polyethylene fibre silk thread between described filler and PVC oversheath.
Concrete, described filler is formed by foam-like fluoropolymer.
Concrete, described polyethylene fibre silk thread is at least provided with 2, is separately positioned on the symmetrical both sides of all some cable cores.
The utility model has the following advantages and beneficial effect compared to existing technology:
1, the utility model makes cable when causing friction because of interface pressure by arranging filler, prior to cable core conductor distortion, effectively alleviates cable core conductor by extraneous frictional force; PVC oversheath adopts flat simultaneously, guarantees that cable softness is good, for laying installation is provided convenience; Between filler and PVC oversheath, be provided with polyethylene fibre silk thread, the intensity of whole cable monomer increased, not easy fracture, useful life increases.
2, by being spirally wound around horizontal winding layer in insulating barrier periphery, the collision of available buffer BENDING PROCESS multiply twisted line conductor, and effectively improve heat-proof quality, the insulation property of cable, and resistance to tension strengthens.
Accompanying drawing explanation
Fig. 1 is the profile of cable in the utility model embodiment.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, the present embodiment provides a kind of withstand voltage anti-fracture cable, comprise some cable cores 1, described cable core 1 periphery is equipped with insulating barrier 2, also comprises the PVC oversheath 3 in flat, and described insulating barrier 2 periphery is spirally wound with horizontal winding layer 4, the periphery of described horizontal winding layer is provided with filler 5, be extruded in described PVC oversheath 3 outside filler, described cable core 1 is the stranded rope-lay strand of many conductor wires, is provided with polyethylene fibre silk thread 6 between described filler 5 and PVC oversheath 3.
In the present embodiment, described filler 5 is formed by foam-like fluoropolymer.
In order to ensure the tensile strength of cable, described polyethylene fibre silk thread 6 is at least provided with 2, is separately positioned on the symmetrical both sides of all some cable cores 1.
The utility model makes cable when causing friction because of interface pressure by arranging filler, prior to cable core conductor distortion, effectively alleviates cable core conductor by extraneous frictional force; PVC oversheath adopts flat simultaneously, guarantees that cable softness is good, for laying installation is provided convenience; Between filler and PVC oversheath, be provided with polyethylene fibre silk thread, the intensity of whole cable monomer increased, not easy fracture, useful life increases; Cable bend durability is strong, pliability is high.
Above-described embodiment is the utility model preferably execution mode; but execution mode of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection range of the present utility model.
