Utility model content
The purpose of this utility model be to provide a kind of can make cable core conductor heat radiation avoid the water-proof cable that conductor is aging.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of water-proof cable, including cable core, described cable core is made by twisting by conductor and waterproofing rope, wrapped waterstop closely it is provided with outside described cable core, it is provided with silicone grease layer between described wrapped waterstop and cable core, screen layer closely it is provided with outside described wrapped waterstop, insulating barrier closely it is provided with outside described screen layer, described insulating barrier is externally provided with heat dissipating layer, described heat dissipating layer is externally provided with protective metal shell, is closely provided with oversheath outside described protective metal shell.
By using technique scheme, the cable core that conductor and waterproofing rope are made by twisting, waterproofing rope is filled with the gap between conductor, and prevent from moisture from passing through cable core spreading in the cable, wrapped waterstop it also avoid water and enters cable core, silicone grease layer has good waterproof sealing performance and has good heat conductivity, the heat transfer that can be produced by conductor is to wrapped water blocking layer, the heat that conductor produces is transferred out by heat dissipating layer, avoid conductor aging, owing to oversheath is in close contact with protective metal shell, effect at bigger pressure, protective metal shell is bondd well with the inner surface of oversheath, thus plug moisture and penetrate into the approach of cable, reach good block-water effect, protective metal shell and oversheath jointly act on and reach the purpose that blocks water.
This utility model is further arranged to: described heat dissipating layer is made up of the silica gel that with the addition of glass fibre.
By using technique scheme, the silica gel that with the addition of glass fibre has excellent insulating properties and good heat conductivity, can well be passed and increase the tensile property of cable by the heat that conductor produces.
This utility model is further arranged to: described cable core at least two.
By using technique scheme, plural cable core ensures the transmission capacity of cable.
This utility model is further arranged to: described oversheath is made up of the polyethylene extruding.
By using technique scheme, the polyethylene extruded, is that by extrusion moulding, polyethylene is wrapped in cable outer layer, makes polyethylene contact with protective metal shell closely, prevents water from entering cable.
This utility model is further arranged to: described conductor trypsin method has one layer of water-proofing powder.
By using technique scheme, water-proofing powder does not increase the external diameter of thick cable, does not change the size of cable, makes mutually to block water between conductor, adds the block-water performance that cable is overall.
This utility model is further arranged to: described insulating barrier is made up of polyvinylidene fluoride.
By using technique scheme, polyvinylidene fluoride has excellent resist chemical and good electrical insulation capability, it is possible to well completely cut off charged conductor, owing to it has resistant to hydrolysis performance, is therefore suitable for cable insulation in water and uses.
In sum, this utility model has the advantages that the cable that conductor and waterproofing rope are made by twisting reduces the gap between conductor, water is made to be difficult to flow between conductor, protective metal shell and the polyethylene extruded jointly act on and play good block-water effect, the setting of heat dissipating layer avoids conductor heat can not distribute out, thus cause conductor aging, affect service life.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of water-proof cable, see figures.1.and.2, including cable core 11, described cable core 11 is made by twisting by conductor 1 and waterproofing rope 3, and described cable core 11 is outer is closely provided with wrapped waterstop 10, it is provided with silicone grease layer 9 between described wrapped waterstop 10 and cable core 11, the outer screen layer 8 that is closely provided with of described wrapped waterstop 10, described screen layer 8 is outer is closely provided with insulating barrier 7, and described insulating barrier 7 is externally provided with heat dissipating layer 6, described heat dissipating layer 6 is externally provided with protective metal shell 5, and described protective metal shell 5 is outer is closely provided with oversheath 4.The cable core 11 that conductor 1 and waterproofing rope 3 are made by twisting, waterproofing rope 3 is filled with the gap between conductor 1, and prevent from moisture from passing through cable core 11 spreading in the cable, wrapped waterstop 10 it also avoid water and enters cable core 11, silicone grease layer 9 has good waterproof sealing performance and has good heat conductivity, the heat transfer that can be produced by conductor 1 gives wrapped waterstop 10, the heat that conductor 1 produces is transferred out by heat dissipating layer 6, avoid conductor 1 aging, owing to oversheath 4 is in close contact with protective metal shell 5, effect at bigger pressure, the polyethylene film on protective metal shell 5 surface is bondd well with the inner surface of oversheath 4, thus plug moisture and penetrate into the approach of cable, reach good block-water effect, protective metal shell 5 and oversheath 4 jointly act on and reach the purpose that blocks water.
