The single-core high-voltage radial water-blocking cable has good water-blocking performance, and can be used in submarine data signal transmission.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of water-proof cable.
Background technology
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 a kind of single core high-pressure radial water repellent electric cable, improve the water resistance of cable, ensure wired signal transmission ability.
The object of the present invention is achieved like this: a kind of single core high-pressure radial water repellent electric cable, it is characterized in that, comprise water-blocking conductor, the periphery of described conductor is surrounded with conductor shield, the periphery of conductor shield is extruded with XLPE insulating barrier, the periphery of described XLPE insulating barrier is surrounded with insulation screen, the periphery of described insulation screen is surrounded with interior semiconductive and blocks water expansion buffer layer, the block water periphery of expansion buffer layer of described interior semiconductive is coated with bamboo joint type metallic aluminium sheath, and the periphery of described bamboo joint type metallic aluminium sheath is extruded with oversheath.
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 conductor shields, 3XLPE insulating barrier, 4 insulation screens, in 5, semiconductive blocks water expansion buffer layer, 6 bamboo joint type metallic aluminium overcoats, 7 oversheaths.
Embodiment
One list core high-pressure radial water repellent electric cable as shown in Figure 1, comprise water-blocking conductor 1, the periphery of conductor is surrounded with conductor shield 2, the periphery of conductor shield 2 is extruded with XLPE insulating barrier 3, the periphery of XLPE insulating barrier 3 is surrounded with insulation screen 4, the periphery of insulation screen 4 is surrounded with interior semiconductive and blocks water expansion buffer layer 5, the block water periphery of expansion buffer layer 5 of interior semiconductive is surrounded with bamboo joint type metallic aluminium sheath 6, the periphery of bamboo joint type metallic aluminium sheath 6 is extruded with oversheath 7, oversheath 7 adopts pvc material to make, conductor shield 2 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.
