The object of the present invention is achieved like this: a kind of seabed three core armouring radial water-resisting cable, it is characterized in that, comprise three cable cores twisted together, the periphery of three cable cores is surrounded with inner sheath, the periphery of inner sheath is coated with armour, the periphery of armour is extruded with oversheath, three cable core structures are identical, cable core comprises the water-blocking conductor at the center of being arranged on, the periphery of described water-blocking conductor is surrounded with conductor shield, the periphery of conductor shield is surrounded with XLPE insulating barrier, the periphery of described XLPE insulating barrier is extruded 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, metal screen layer periphery is surrounded with outer semiconductor waterstop, the periphery of outer semiconductor waterstop is surrounded with aluminium-plastic tape, the periphery of aluminium-plastic tape is coated with fire retardant jacket, water-proofing powder is filled with between fire retardant jacket and inner sheath.
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, semiconductor waterstop in 5,6 metal screen layers, 7 outer semiconductor waterstop, 8 aluminium-plastic tapes, 9 fire retardant jackets, 10 water-proofing powders, 11 inner sheaths, 12 armours, 13 oversheaths.
Embodiment
A kind of seabed three core armouring radial water-resisting cable as shown in Figure 1, comprise three cable cores twisted together, the periphery of three cable cores is surrounded with inner sheath 11, the periphery of inner sheath 11 is coated with armour 12, the periphery of armour 12 is extruded with oversheath 13, three cable core structures are identical, cable core comprises the water-blocking conductor 1 at the center of being arranged on, the periphery of described water-blocking conductor 1 is surrounded with conductor shield 2, the periphery of conductor shield 2 is surrounded with XLPE insulating barrier 3, the periphery of described XLPE insulating barrier 3 is extruded with insulation screen 4, the periphery of insulation screen 4 is surrounded with interior semiconductor waterstop 5, the periphery of interior semiconductor waterstop 5 is coated with metal screen layer 6, metal screen layer 6 periphery is surrounded with outer semiconductor waterstop 7, the periphery of outer semiconductor waterstop 7 is surrounded with aluminium-plastic tape 8, the periphery of aluminium-plastic tape 8 is coated with fire retardant jacket 9, water-proofing powder is filled with between fire retardant jacket 9 and inner sheath 11, oversheath 13 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.
