Abstract
Disclosed is a waterproof power cable. The cable comprises a conductor, a waterproof band wrapping the periphery of the conductor, an insulation layer or a liner layer wrapping the periphery of the waterproof band, a jacket wrapping the periphery of the insulation layer or the liner layer. The cable further comprises a waterproof ointment wrapping the periphery of the conductor. In the longitudinal direction, the novel cable structure provided by the utility model allows the conductor to carry out dip-coating of the waterproof ointment and be winded by the waterproof band, so that gap between the conductor and the insulation jacket is eliminated and water is prevented from entering the cable. In the transverse direction, the cable utilizes one-time extrusion of the insulation (or the liner layer) and the jacket and utilizes an extrusion manner to extrude the insulation jacket. Gap between the cable core and the insulation (or the liner layer) jacket can be filled, and the jacket and the insulation (or the liner layer) are melted as one, so that the gap between the jacket and the insulation (or the liner layer) is eliminated and good waterproof effects are achieved.
Description
[technical field]
The utility model relates to a kind of power cable field.
[background technology]
Along with the high speed development of national economy, industry field is constantly expanded, and cable is used widely under varying environment.The water resistance of power cable more and more is taken seriously, and the power cable that zone over strait, ,Kua river, region as moist as south, zone, island etc. are used must be through under water, or be soaked in fully in water, and this just needs cable that water resistance need to be arranged.The conventional electric power cable is also limited to the retardation of water.
[utility model content]
Technical problem to be solved in the utility model is: a kind of new waterproof power cable is provided, makes up the block water defect of aspect of existing control cables, can, from radially and vertical integrated water stop, reach superior block-water effect.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of waterproof power cable, comprise the conductor that sets gradually from inside to outside, longitudinal water-blocking layer, insulating barrier, longitudinal water-blocking wrapped, and the radial water-resisting restrictive coating of filling, block water, described longitudinal water-blocking layer is wrapped outside conductor.
Compared with prior art, the utility model adopts the new construction of cable, adopts in the vertical conductor dip-coating waterproofing unction, wrapped waterstop, and the gap between elimination conductor and insulating sleeve arrives the cable that enters of retained water; Employing is in the horizontal insulated (or inner covering) and sheath is disposable extrudes, and adopts fashion of extrusion to extrude insulating sleeve.The gap that both can fill between cable core and insulation (or inner covering) sheath is closely knit, sheath and molten being integrated of insulation (or inner covering) can be eliminated to gap between the two again, with reaching good waterproof effect.
[accompanying drawing explanation]
Fig. 1 is the first embodiment of the utility model waterproof power cable.
Fig. 2 is the second embodiment of the utility model waterproof power cable.
[main element symbol description]
Conductor 1 waterproof power cable 100,200
Insulating barrier 4 sheaths 5
Inner covering 6
Following embodiment further illustrates the utility model in connection with above-mentioned accompanying drawing.
[embodiment]
As shown in Figure 1, for meeting the first embodiment of waterproof power cable 100 of the present utility model.
As shown in Figure 2, for meeting the second embodiment of waterproof power cable 200 of the present utility model.
Can reach good waterproof effect for adapting to, the whole dip-coating one deck of cable conductor 1 waterproofing unction, and wrapped one deck waterstop, the insulating barrier 4 of single-core cable and sheath 5 adopt disposable extruding, and eliminate layering and extrude existing gap.The stranded filling greasy for preventing water of multicore cable insulation stranding, inner covering 6 and sheath 5 is disposable extrudes, eliminate the gap existed between inner covering 6 and sheath 5.
Cable conductor 1 meets the regulation of GB/T3956 standard, the whole dip-coating waterproofing unction 2 of conductor 1, more wrapped waterstop 3, and single-core cable adopts disposable extruded insulation layer 4 and sheath 5.The multicore cable twisted synthesizing cable, fill waterproofing unction 2, disposable inner covering 6 and the sheath 5 of extruding.
Compared with prior art, the utility model adopts the new construction of cable, adopts in the vertical conductor dip-coating waterproofing unction, wrapped waterstop, and the gap between elimination conductor and insulating sleeve arrives the cable that enters of retained water; Employing is in the horizontal insulated (or inner covering) and sheath is disposable extrudes, and adopts fashion of extrusion to extrude insulating sleeve.The gap that both can fill between cable core and insulation (or inner covering) sheath is closely knit, sheath and molten being integrated of insulation (or inner covering) can be eliminated to gap between the two again, with reaching good waterproof effect.
