The utility model adopts a technical scheme that, the conductor shielding layer is arranged between the conductor and the insulating layer, and the insulation screen, the metal woven shield, the belting layer, the inner sheath, the fiber sleeving, the waterproofing belt and the outer sheath are arranged between the insulating layers, overcomes the defect that prior salt lake hydraulicking machine power supply high pressure flexible cable can not stably provide high pressure power for a long time, which not only has higher flexibility, stronger tensile, tensile property and mechanical property, but also slippery surface, water viscosity proof, salt deposition proof, corrosion proof, weather proof and long service life, fit for the salt lake hydraulicking machine power supply high pressure flexible cable.
Description
Technical field
The utility model relates to a kind of high-tension cable, relate in particular between conductor and the insulating barrier and establish conductor shield, insulating barrier is established the salt lake hydromining machine power supply high voltage flexible cable of insulation screen, metal knitted screen, belting layer, sheath, fibrage layer, waterstop and oversheath outward successively.
Background technology
The hydromining machine that is used for the salt lake at present, its environment for use is to be at random all to be immersed in the saturated bittern, and the flexural loading need bear hydromining machine walking and strong wind the time, require cable surface not salt crust, water-fastly soak, the weather condition and to keep cable long-term, stablize, high voltage supply.
Summary of the invention
At above-mentioned situation, the purpose of this utility model is to provide a kind of salt lake hydromining machine power supply high voltage flexible cable, its existing high pressure resistant preferably, corrosion-resistant, water-fast performance of soaking has stronger tension, anti-Zhang Zuoyong and higher softness and the round-the-clock environment that can adapt to water logging work for a long time again.
To achieve these goals, a kind of salt lake hydromining machine power supply high voltage flexible cable, it mainly comprises conductor, insulating barrier, screen, oversheath, be provided with conductor shield between its conductor and the insulating barrier, insulating barrier is provided with insulation screen, metal knitted screen, belting layer, sheath, fibrage layer, waterstop and oversheath outward successively.
For implementation structure optimization, its further step is:
Conductor is the tin-coated copper twisted wire.
Conductor shield comprises that semi-conductive tape covering and semiconductive extrude layer.
Insulation screen comprises that semiconductive extrudes layer and semi-conductive tape covering.
Metal knitted screen is a tinned copper wire.
The fibrage layer is the high tenacity polyester fiber silk.
Waterstop is a rapid expanding formula waterstop.
Sheath and oversheath are the chlorosulfonated polyethylene rubber layer.
The utility model is used between conductor and the insulating barrier and establishes conductor shield, insulating barrier is established the technical scheme of insulation screen, metal knitted screen, belting layer, sheath, fibrage layer, waterstop and high anti-tear, ganoid rubber outer protection cover outward successively, overcome existing salt lake hydromining machine with the power supply high voltage flexible cable can't high voltage supply steady in a long-term defective.
The beneficial effect that the utility model is produced compared to existing technology:
(I) multilayers protections such as the outer wrapped and extruded insulation screen of conductor, insulating barrier, insulation screen, metal knitted screen, fibrage layer, making it have higher softness and every technical indicator, to reach rated voltage be U
0The national standard of/U8.7/15KV cable.
(II) high tenacity polyester fiber silk braiding, tension, anti-Zhang Zuoyong are stronger.
(III) fibrage layer peripheral hardware rapid expanding formula water blocking tape can adapt to long-term water logging, bubble operational environment.
(IV) sheath, oversheath adopt high anti-tear, ganoid elastomeric material, have both had flexility and mechanical performance preferably, and smooth surface does not again get wet, salt crust not, corrosion-resistant, weather, long service life.
It is fit to hydromining machine power supply high voltage flexible cable in the salt lake.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of salt lake of the present utility model hydromining machine with the power supply high voltage flexible cable.
Among the figure 1, conductor, 2, conductor shield, 3, insulating barrier, 4, insulation screen, 5, metal knitted screen, 6, belting layer, 7, sheath, 8, the fibrage layer, 9, waterstop, 10, oversheath.
Embodiment
Referring to accompanying drawing, a kind of salt lake hydromining machine power supply high voltage flexible cable, it is made up of conductor 1, conductor shield 2, insulating barrier 3, insulation screen 4, metal knitted screen 5, belting layer 6, sheath 7, fibrage layer 8, waterstop 9, oversheath 10.Conductor 1 is made by the tin-coated copper twisted wire, and conductor shield 2 extrudes layer by semi-conductive tape covering and semiconductive to be formed, and for good electrical property is arranged, insulating barrier 3 usefulness high pressure ethylene-propylene rubber are made.Insulation screen 4 extrudes layer by semiconductive to be formed with the semi-conductive tape covering, and metal knitted screen 5 adopts tinned copper wire to make, and it both can shield, and also can play booster action.Fibrage layer 8 adopts the braiding of high tenacity polyester fiber silk, and the braiding of high tenacity polyester fiber silk fiber has stronger tension, anti-Zhang Zuoyong when can make cable keep soft.Waterstop adopts meets the rapid expanding formula waterstop that water expands rapidly, plays the effect of reinforcement when it both can guarantee the cable softness, and can prevent that moisture from infiltrating to the cable internal layer.Sheath 7 and oversheath 10 adopt the chlorosulfonated polyethylene rubber material, do not get wet, not salt crust.So cable is being followed under the frequently mobile operational environment of hydromining machine, has long-term use, softness and reliable.
Below only be preferred embodiment of the present utility model, according to above-mentioned design of the present utility model, those skilled in the art also can make various modifications and conversion to this.For example, between conductor and the insulating barrier, between insulating barrier and the screen and combining of other revise and conversion.Yet similar this conversion and modification all belong to essence of the present utility model.
