Abstract
The invention provides a waterproof shielding armored cable comprising a plurality of conductive wires. After the conductive wires are intertwisted into the cable, an oversheath is arranged outside the cable. Each conductive wire comprises a conductor and a polyvinyl chloride insulation layer. A conductor shielding layer is arranged between each conductor and each polyvinyl chloride insulation layer. Water proof layers fill gaps among the plurality of conductive wires. A metal shielding layer is arranged outside the water proof layers. A water-resistant lapped wrapping layer is arranged outside the metal shielding layer. An inner sheath is arranged outside the water-resistant lapped wrapping layer. An armor layer is arranged between the inner sheath and the oversheath. According to the invention, the usage life of the cable can be substantially raised, and the waterproof shielding armored cable is applicable to areas which have mines and which are low-lying and rich in rain, etc.
Description
Technical field
The present invention relates to a kind of power cable, relate in particular to a kind of waterproof shielding armoured cable.
Background technology
At present, the cable on market is divided into water-proof cable, submersible pump cable, water-fast cable, flame retardant cable more.These cables are all applicable to different operating mode demands.General use flame retardant cable in mine, but the humidity in mine is larger, and water has certain permeability to insulating material, affects the working life of cable.Physical features in mine is complicated, and cable, when being subject to External Force Acting, is easy to damage; In addition owing to there being gap between multiple conducting wires, and the electric strength of filling place insulating material own is lower, so the integral insulation level of cable declines, and affects the useful life of cable.
Summary of the invention
Technical problem to be solved by this invention is to overcome defect of the prior art, and a kind of waterproof shielding armoured cable is provided, and not only has water-proof function, and has function of shielding, greatly improves the useful life of cable.
For solving the problems of the technologies described above, the invention provides a kind of waterproof shielding armoured cable, comprise multiple conducting wires, peripheral hardware oversheath after multiple conducting wires twisted synthesizing cable, every wire comprises conductor and polyvinyl chloride insulation layer, between conductor and polyvinyl chloride insulation layer, be provided with conductor shield, gap-fill watertight composition between multiple conducting wires, watertight composition peripheral hardware metal screen layer, the metal screen layer peripheral hardware lapping layer that blocks water, the lapping layer peripheral hardware inner sheath that blocks water, is provided with armour between inner sheath and oversheath.
As a further improvement on the present invention, watertight composition adopts radially waterproof material.
As a further improvement on the present invention, the lapping layer that blocks water adopts longitudinal water-blocking material.
The beneficial effect that the present invention reaches: the invention provides a kind of waterproof shielding armoured cable, in the useful life that can greatly improve cable, be applicable to mine, the low-lying area such as rainy.
Accompanying drawing explanation
Fig. 1 is the structural representation of waterproof shielding armoured cable.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, the invention provides a kind of waterproof shielding armoured cable, comprise multiple conducting wires, peripheral hardware oversheath 9 after multiple conducting wires twisted synthesizing cable, every wire comprises conductor 1 and polyvinyl chloride insulation layer 3, between conductor 1 and polyvinyl chloride insulation layer 3, be provided with conductor shield 2, gap-fill watertight composition 4 between multiple conducting wires, watertight composition 4 peripheral hardware metal screen layers 5, the metal screen layer 5 peripheral hardwares lapping layer 6 that blocks water, the lapping layer 6 peripheral hardware inner sheaths 7 that block water, are provided with armour 8 between inner sheath 7 and oversheath 9, and insulating barrier 3 is comprised of polyvinyl chloride or polyethylene; Watertight composition 4 and the lapping layer 6 that blocks water adopt respectively radially waterproof material and longitudinal water-blocking material, prevent thoroughly the infiltration of hydrone.Not only there is water-proof function, and there is function of shielding, greatly improve the useful life of cable.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
