Abstract
The invention discloses a water-resistant anticorrosive comprehensive sheath medium-voltage cable which belongs to the technical field of wire cables and comprises a conductive cable core, a filling layer, a water-resistant envelope, an inner sheath and an outer sheath, wherein the filling layer is an expanded water-resistant filling layer; the inner sheath is in a double-layer structure; after an aluminum plastic composite tape is longitudinally wrapped to form a metal closed sheath, a layer of macromolecular polyethylene sheath is extruded and wrapped; the outer sheath is a composite modified plastic outer sheath; the composite modified plastic outer sheath is a wear-resistant outer sheath formed by adding rubber and a wear-resistant plasticizer to PVC resin as a base material, and water or water vapor cannot radially enter the cable; even if the water enters from the end of the cable, the water cannot flow in the cable; thereby, the influence caused by the water or the water vapor after entering the cable is solved; and by adopting the composite modified plastic outer sheath, low-temperature conditions, water immersion, acidproof performance, alkali resistant performance, corrosion resistant performance and the like are obviously improved.
Description
Technical field
The invention belongs to technical field of electric wires and cables, refer in particular to a kind of anticorrosion composite sheath midium voltage cable that blocks water, be applicable to coastal waters, lake, chemical industry or lay the midium voltage cable field of circumstance complication.
Background technology
Chinese patent ZL200620040562.X discloses a kind of " the high voltage substation pilot protection is with anticorrosion waterproof guide cable "; Have conductor group and water-blocking material in the cable core; Between the belting layer of cable core and oversheath, inner covering, screen, aluminium alloy covering, inner sheath and armour are set; This cable has good vertical block-water effect, but it is not high with corrosion resistance radially to block water.
Chinese patent ZL200820200194.X discloses a kind of " anticorrosion power cable ", includes sheath, the twining package tape that blocks water, the filler that blocks water, insulation and conductor; The importance that this cable has been stressed to block water and filled also have good vertical block-water effect, but radially block-water performance is poor.
Chinese patent ZL03233672.1 discloses a kind of " power cable of the moisture-proof anticorrosive that blocks water erosion "; Include and adopted filling water blocking yarn, the vertical two-sided plastic-aluminum band of bag of embossing and polyethylene adhesion coating; Possesses good vertical and radially moistureproof block-water effect; But put forth effort on the adjustment of structure and packing material, improvement is not made in the moisture content immersion of electric power outermost layer-oversheath and the Corrosion Protection of acid-fast alkali-proof.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency; A kind of anticorrosion composite sheath midium voltage cable that blocks water is provided; Main two-layer composite sheath and the corrosion-resistant oversheath of being set to of outermost that is cable that improve; Composite sheath is the double-decker of aluminum plastic composite belt longitudinal bag (PUR bonding) and the combination of high-molecular polythene sheath, and corrosion-resistant oversheath is to be the modified plastics oversheath that base adds rubber and corrosion-resistant plasticizer with the Corvic.Specifically be to implement like this: anticorrosion composite sheath midium voltage cable blocks water; Comprise conductor wire core, packed layer, the covering that blocks water, inner sheath, oversheath; It is characterized in that packed layer is the intumescent packed layer that blocks water; Inner sheath is a double-decker; Be to extrude one deck high-molecular polythene sheath again after the aluminum plastic composite belt longitudinal bag forms metal enclosed cover; Oversheath is composite type modified plastics oversheath, and described composite type modified plastics oversheath is to be the corrosion-resistant oversheath that base adds has rubber and corrosion-resistant plasticizer with the Corvic.
Closely fill with the dilatancy waterproofing rope during conductor wire core stranding of the present invention,, prevent that effectively cable socket from having the endosmosis after water immerses with double-deck wrapped the tightening of waterstop.
Conductor wire core is outside conductor, to set gradually water blocking layer, internal shield, insulating barrier, outer shielding layer and metal screen layer.
The present invention coats and the material water-proof material filling through outside the cable core of cable, adopting comprehensive inner sheath; Make water or the aqueous vapor can't be from radially getting into cable; Even water gets into from cable socket, can not in cable, flow, thereby solve the influence that produces behind water or the aqueous vapor entering cable; Through adopting composite type modified plastics oversheath; Made tangible improvement at the immersion of cryogenic conditions, water, the aspects such as Corrosion Protection of acid-fast alkali-proof, resistance to low temperature-40 ℃ or lower, high temperature resistant long-term use is 120 ℃; Short-term is used 220～250 ℃, has suitable decay resistance.
