Along with the development of telecommunications, more and more higher to the quality requirement of telecommunication cable.For the outdoor use telecommunication cable, normal owing to baiting of meiofauna such as suffering vole, hare damaged.In addition, China exists the place of termite also more, and the formic acid of termite secretion also often causes fatal damage to cable.Cable in use unavoidably contacts with moisture, if the cable block-water effect is bad, after the cable conductor immersion, often causes cable capacitance to become big, and insulation resistance reduces, and causes signal transmission distortion or failure.Insulating barrier can produce " water is tree-shaped " under effect of electric field simultaneously, causes insulation accelerated wearing out, thereby causes cable fault.
Therefore, at present be badly in need of improving the termite-resistant rodent-resistant and the block-water performance of cable,, improve cable useful life, reduce the cable maintenance expense to guarantee cable stability.
The utility model content
At above problem, the utility model provides a kind of rat-proof and ant-proof water resistance communication cable.
A kind of rat-proof and ant-proof water resistance communication cable, comprise successively from inside to outside: cable core, belting layer, interior water blocking tape layer, the aluminium strip screen, inner restrictive coating, belt blocks water outward, the steel-tape armouring layer, termite-resistant rodent-resistant high density polyethylene (HDPE) restrictive coating and termite-resistant rodent-resistant crosslinked polyethylene restrictive coating, described cable core is coated with belting layer, interior water blocking tape layer, the vertical outward alclad band screen of described water blocking tape layer, outside the aluminium strip screen, extrude the high density polyethylene (HDPE) inner restrictive coating, belt blocks water outside wrapped outside inner sheath, outside waterstop, be provided with the steel-tape armouring layer, outside the steel-tape armouring layer, extrude termite-resistant rodent-resistant high density polyethylene (HDPE) restrictive coating and termite-resistant rodent-resistant crosslinked polyethylene restrictive coating respectively, at cable core, belting layer, interior water blocking tape layer, screen, belt blocks water outward, in the steel-tape armouring lamellar spacing, the even continuous filling petroleum jelly that blocks water respectively.
Above-mentioned rat-proof and ant-proof water resistance communication cable, wherein, described in water blocking tape layer, block water that to be the waterstop of two-layer 0.2～0.5mm overlapping wrapped for belt outward.
Above-mentioned rat-proof and ant-proof water resistance communication cable, wherein, described cable core comprises that N is to (N 〉=1) stranded insulated conductor.
Above-mentioned rat-proof and ant-proof water resistance communication cable, wherein, described belting layer is that the multi-layered polyester band is overlapping wrapped.
Above-mentioned rat-proof and ant-proof water resistance communication cable, wherein, described aluminium strip screen is that the aluminium-plastic tape of 0.3mm vertical bag behind embossing forms by thickness.
Above-mentioned rat-proof and ant-proof water resistance communication cable, wherein, described steel-tape armouring layer is that the vertical bag of wrinkle composite steel-plastic belt of 0.2～0.6mm forms by thickness.
Above-mentioned rat-proof and ant-proof water resistance communication cable outside described steel-tape armouring layer, extrudes termite-resistant rodent-resistant high density polyethylene (HDPE) restrictive coating earlier, extrudes termite-resistant rodent-resistant crosslinked polyethylene restrictive coating again.
The beneficial effects of the utility model are, adopt the waterstop of block water petroleum jelly and water-swellable to block water in the cable gap, have greatly improved the axial block-water performance of cable.Cable employing aluminium strip and high density polyethylene (HDPE) inner sheath, steel band, termite-resistant rodent-resistant high density polyethylene (HDPE) oversheath, termite-resistant rodent-resistant crosslinked polyethylene oversheath can effectively stop the radially immersion of moisture.Aluminium strip steel band double layer screen armouring can effectively improve the cable anti-electromagnetic interference capability in addition.Cable adopts steel-tape armouring, the mode that oversheath adopts termite-resistant rodent-resistant high density protective cover material and termite-resistant rodent-resistant crosslinked polyethylene protective cover material to combine, effectively improve the mechanical and physical performance and the environmental resistance of cable, the termite-resistant rodent-resistant effect to cable has played retrocession simultaneously.

Embodiment
The utility model provides a kind of rat-proof and ant-proof water resistance communication cable, and as shown in Figure 1, in the present embodiment, cable core 1 comprises that N is to (N 〉=1) stranded insulated conductor.The cable core 1 outer belting layer 3 that is provided with, water blocking tape layer 4 in the belting layer 3 outer overlapping coatings.Being provided with one deck thickness outside the interior water blocking tape layer 4 is two-sided plastic-coated aluminium strip overlapping vertical aluminium strip screen 5 that packs behind embossing of 0.3mm.Outside aluminium strip screen 5, extrude the inner restrictive coating 6 of one deck high-density polyethylene material, the inner restrictive coating 6 outer overlapping wrapped outer belts 7 that block water, indulge the steel-tape armouring layers 8 of bag thickness 0.2～0.6mm outside outside the water blocking tape layer 7, outside armour 8, extrude termite-resistant rodent-resistant high density polyethylene (HDPE) restrictive coating 9, outside termite-resistant rodent-resistant high density polyethylene (HDPE) restrictive coating 9, extrude termite-resistant rodent-resistant crosslinked polyethylene restrictive coating 10.Cable core 1, belting layer 3, interior water blocking tape layer 4, screen 5, outside block water in the gaps such as belt 7, steel-tape armouring layer 8, evenly fill the petroleum jelly 2 that blocks water respectively.
In the present embodiment cable core 1, belting layer 3, interior water blocking tape layer 4, screen 5, outside block water in the gaps such as belt 7, steel-tape armouring layer 8, evenly fill the petroleum jelly 2 that blocks water respectively.Can stop the immersion of axial moisture, in addition, between belting layer 3 and screen 5, be provided with the interior water blocking tape layer of water-swellable between inner restrictive coating 6 and the steel-tape armouring layer 8, immerse if any moisture, the cable gap is stopped up in water blocking tape layer meeting imbibition, prevents that moisture from immersing.The vertical alclad band screen 5 outer high density polyethylene (HDPE) inner restrictive coatings 6 that extrude in the present embodiment, vertical alclad band screen plays anti-interference effect, and the air-tightness of metal is good simultaneously, can prevent the radially immersion of moisture.The high density polyethylene (HDPE) inner restrictive coating that extrudes, the vertical bag of sealing aluminium strip seam plays the moisture-proof role that blocks water, and simultaneously aluminium strip is played a protective role.Present embodiment adopts vertical Baogang band armour 8, its outer termite-resistant rodent-resistant high density polyethylene (HDPE) restrictive coating 9 and termite-resistant rodent-resistant crosslinked polyethylene restrictive coating 10 of extruding.Present embodiment adopts the vertical bag of steel band armouring, when playing the rat-proof and ant-proof water resistance effect, further improves the anti-electromagnetic interference capability of cable.Because the air-tightness of high density polyethylene (HDPE), block-water effect is good, and the flexibility of crosslinked polyethylene protective cover material, anti-extrusion ability and environmental stress resistance are better, the mode that present embodiment adopts both to combine, make full use of both advantages, effectively improve the protection against the tide that blocks water, mechanical and physical performance and the environmental resistance of cable.Present embodiment adopts steel-tape armouring and double-deck termite-resistant rodent-resistant sheath that cable termite-resistant rodent-resistant effect has been played retrocession.
