In preferred scheme, power cable and telecommunication cable are arranged separately in groups, and power cable and telecommunication cable are respectively provided with many groups, outside power cable, be provided with metal screen layer.
In preferred scheme, outside telecommunication cable, be provided with metal screen layer.
In preferred scheme, be also provided with optical cable.
In preferred scheme, optical cable is wire armoring reinforced fiber.
In preferred scheme, optical cable, power cable and telecommunication cable entirety be coated with mothproof ship worm layer.
In preferred scheme, anti-shipworm layer be coated with steel wire armor layer and polypropylene rope serving.
In preferred scheme, between anti-shipworm layer and steel wire armor layer, be also provided with polypropylene rope serving.
In preferred scheme, the polypropylene rope serving outside steel wire armor layer is at least two-layer.
A kind of rubber filling conductor that the utility model provides blocks water submarine cable, has following beneficial effect:
1, conductor blocks water is by adopting the mode of filled rubber, making the gap between conductor be filled up by rubber completely, be applicable to the submarine cable project of the larger depth of water.
2, on common wire twisting equipment, install crowded rubber equipment additional can realize, equipment investment is relatively little.
3, compared with traditional water-blocking conductor, the utility model can meet the higher requirement that blocks water.And the effect blocked water can be played in the seawater.
4, optical cable and telecommunication cable and electric power transfer use identical carrier, make transmission line can carry out communication operations while transferring electric power, and monitor at any time and transmit submarine cable running status; Greatly reduce laying installation cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is cross-sectional cut-away schematic diagram of the present utility model.
In figure: conductor 1, insulation screen 2, power cable 4, telecommunication cable 5, anti-shipworm layer 6, polypropylene rope serving 7, steel wire armor layer 8, optical cable 9.
Embodiment
As in Fig. 1, a kind of rubber filling conductor blocks water submarine cable, comprises power cable 4 and telecommunication cable 5, power cable 4 and telecommunication cable 5 be coated with insulation screen 2, between power cable 4 and the conductor 1 of telecommunication cable 5, between conductor 1 and insulation screen 2, be filled with rubber.In this example, rubber is filled between conductor by the mode with extrusion packing, and between conductor 1 and insulation screen 2, the rubber within insulation screen 2 is as a whole.This is except increasing insulation effect, and also reduce the cost of processing, on common wire twisting equipment, only install crowded rubber equipment additional can realize, and equipment investment is relatively little, and processing step is relatively simple.Conductor in this example refers to single conductive unit, such as single copper wire, after conductive unit is stranded, then carries out the extruding of rubber, and rubber can penetrate in the gap between copper wire and between copper wire and insulation screen 2 under the effect of extruding.
Insulation screen 2 in this example comprises conductor screen, insulation and insulation and screen.
In preferred scheme, power cable 4 and telecommunication cable 5 are arranged separately in groups, as shown in fig. 1, power cable 4 and telecommunication cable 5 are respectively provided with many groups, three groups of power cables 4 and two group communication cables 5 are just had in this example, outside power cable 4, be provided with metal screen layer 3, the metal screen layer 3 in this example is copper strips metal screen layer.Telecommunication cable 5 in this example is that the insulated wire pair twist that 4 groups of rubber filling conductors block water forms.
In preferred scheme, be provided with metal screen layer 3 outside telecommunication cable 5, described metal screen layer 3 is copper strips metal screen layer.
In preferred scheme, be also provided with optical cable 9.In preferred scheme, optical cable 9 is wire armoring reinforced fiber.Preferably the reinforced 12 core monomode fibers of wire armoring are adopted in this example.
