The fast development of electric power related industry makes the demand of toll cable occur increasing substantially, but toll cable laying-out circumstance complication, no matter be laid in soil or water or be erected at aerial, sufficient moisture is all there is in its surrounding environment, after long-time use, moisture infiltrates the loss of communications that cable inside can increase cable greatly, reduce the service efficiency of cable, even cause the generation of the problems such as communication failure, for the water resistance promoting cable just must add necessary water-proofing treatment measure in the structural design of cable.
Summary of the invention
The object of this invention is to provide pressure longitudinally full water repellent electric cable in a kind of multicore, improve the water resistance of cable, ensure wired signal transmission ability.
The object of the present invention is achieved like this: pressure longitudinally full water repellent electric cable in a kind of multicore, it is characterized in that, comprise the wrapped semiconductor waterstop in cable core periphery, the periphery of semiconductor waterstop is surrounded with conductor shield, the periphery of conductor shield is coated with XLPE insulating barrier, the periphery of XLPE insulating barrier is coated with insulation screen, the periphery of insulation screen is surrounded with interior semiconductor waterstop, the periphery of interior semiconductor waterstop is coated with metal screen layer, the periphery of metal screen layer is surrounded with outer semiconductor waterstop, the periphery of outer semiconductor waterstop is vertical is surrounded by aluminium-plastic tape, the periphery of aluminium-plastic tape is extruded with oversheath, described cable core is the many circular aluminum conductors twisted together, between described circular aluminum conductor, water-proofing powder is filled with between circular aluminum conductor and semiconductor waterstop.
As a further improvement on the present invention, described oversheath adopts pvc material to make.
As a further improvement on the present invention, described conductor shield selects zinc-plated proof copper-wire braided to form.
Compared with prior art, beneficial effect of the present invention is, the pvc material that oversheath of the present invention uses is without water-soluble, and can block water to a certain extent, for promoting the radial water resistance of cable, metallic sheath or plastic-aluminum combined layer can be used in oversheath inside, wherein metallic sheath is applicable to the design realization of high-tension cable, the design that plastic-aluminum combined layer is applicable to weight cable realizes, molecules align in complete hermetic metallic sheath is tight, moisture cannot enter into cable inside by it, which achieves the object of cable radial water-resisting, plastic-aluminum combined layer can produce high temperature and high pressure environment when carrying out extruding process with oversheath, airtight adhesiveness can be presented between composite bed surface film under this environment and oversheath top layer, vertical putting up of parlor can present airtight adhesiveness equally, realize the radial water-resisting of centering pressure telecommunication cable.The present invention can be used in seafloor data signal transmission.
Accompanying drawing explanation
Fig. 1 is this construction of cable schematic diagram.
Wherein, 1 conductor, 2 water-proofing powders, 3 semiconductor waterstop, 4 conductor shields, 5XLPE insulating barrier, 6 insulation screens, semiconductor waterstop in 7,8 metal screen layers, 9 outer semiconductor waterstop, 10 aluminium-plastic tapes, 11 oversheaths.
Embodiment
Pressure longitudinally full water repellent electric cable in a kind of multicore as shown in Figure 1, comprise the wrapped semiconductor waterstop 3 in cable core periphery, the periphery of semiconductor waterstop 3 is surrounded with conductor shield 4, the periphery of conductor shield 4 is coated with XLPE insulating barrier 5, the periphery of XLPE insulating barrier 5 is coated with insulation screen 6, the periphery of insulation screen 6 is surrounded with interior semiconductor waterstop 7, the periphery of interior semiconductor waterstop 7 is coated with metal screen layer 8, the periphery of metal screen layer 8 is surrounded with outer semiconductor waterstop 9, the periphery of outer semiconductor waterstop 9 is vertical is surrounded by aluminium-plastic tape 10, the periphery of aluminium-plastic tape 10 is extruded with oversheath 11, described cable core is the many circular aluminum conductors 1 twisted together, between described circular aluminum conductor 1, water-proofing powder 2 is filled with between circular aluminum conductor 1 and semiconductor waterstop 3, oversheath 11 adopts pvc material to make, conductor shield 4 selects zinc-plated proof copper-wire braided to form.
The polythene material that oversheath of the present invention uses is without water-soluble, and can block water to a certain extent, for promoting the radial water resistance of cable, metallic sheath or plastic-aluminum combined layer can be used in oversheath inside, wherein metallic sheath is applicable to the design realization of high-tension cable, and the design that plastic-aluminum combined layer is applicable to weight cable realizes.Molecules align in complete hermetic metallic sheath is tight, and moisture cannot enter into cable inside by it, which achieves the object of cable radial water-resisting.Plastic-aluminum combined layer can produce high temperature and high pressure environment when carrying out extruding process with oversheath, airtight adhesiveness can be presented between composite bed surface film under this environment and oversheath top layer, vertical putting up of parlor can present airtight adhesiveness equally, can realize the radial water-resisting of centering pressure telecommunication cable like this.
For ensureing that cable longitudinally has good block-water performance, material water-proof material must be filled in the gap between stranded core when carrying out Cable Construction Design, the cable design structure needs that can be used for realizing longitudinal water-blocking at present carry out from two levels, first level becomes water-blocking conductor for adding initiatively material water-proof material in wire stranding and compacting process wherein, and the second level is for adding to active material water-proof material when making cable conductor in stranding making.
Those skilled in the art, under the condition not departing from the spirit and scope of the present invention that claims are determined, can also carry out various amendment to above content.Therefore scope of the present invention is not limited in above explanation, but determined by the scope of claims.
