Abstract
The invention provides a large-sectional rubber filled waterproof power cable which comprises three conductors; an internal protecting layer, a copper tape screen and a sheath are arranged outside the three conductors; an internal semi-conducting layer, an insulating layer, an external semi-conductive layer and a water blocking semi-conductive tape are arranged outside each conductor in sequence, rubber filling is filled in the internal protective layer and among the three conductors; and the outermost part of each conductor is longitudinally covered by a plastic-aluminum plastic composite tape. The power cable provided by the invention realizes a triple waterproof function, complete sealing and filling of the power cord of the cable is ensured, and steam is prevented from entering the cable due to the seam between the internal protective layer and the wire core to influence the normal use of the cable. As the rubber material has good flexibility, the bending performance of the cable is improved. The power cable provided by the invention is economic and practical and has excellent electrical performance and mechanical performance; and the waterproof performance of the overall structure of the cable is improved.
Description
Technical field
The present invention relates to a kind of environment-friendly type power cable, the heavy in section rubber that specifically a kind of water proofing property is strong, bending property is good is filled waterproof power cable.
Background technology
In extruding solid insulation power cable IEC60502-2005 standard, rated voltage is that the power cable of 3.6/6kV ~ 26/35kV is a transmission high-voltage power cable, generally fixedly lays use, does not move and uses.If such cable laying is under the environment of humidity; When cable used, aqueous vapor can enter into cable inside along cable conductor, further is penetrated into the insulated wire cores of cable; Cause the core insulation under high-tension effect, to form the water tree, shorten the useful life of cable until cable breakdown.The construction of cable that has now adopts waterstop, waterproofing rope, and the imbibition prevention aqueous vapor of dependence waterstop and waterproofing rope is prolonged cable core and moved, but DeGrain, and cable core still has moisture.The cable core water inlet causes cable breakdown, becomes puzzlement cable manufacturing enterprise and user's a difficult problem.
Summary of the invention
The present invention be directed to the defective that exists in the prior art, provide a kind of simple in structure, can effectively avoid aqueous vapor to get into cable core and the good heavy in section rubber of bending property is filled waterproof power cable.
Realize that above-mentioned purpose adopts following technical scheme: a kind of heavy in section rubber is filled waterproof power cable, comprises three conductors that place the cable center position, and the outer cover of three conductors is equipped with sheath, galvanized steel strip armour and sheath; Each conductor outside also is set with interior semi-conductive layer, insulating barrier, outer semiconducting layer, the semi-conductive tape that blocks water successively, is provided with the rubber filling between said sheath inside, three conductors; The most external of each conductor adopts the aluminum plastic composite belt longitudinal bag.
What said insulating barrier adopted is that the waterproof height of tree is pressed crosslinked polyethylene.
Said rubber is filled and the sheath co-extrusion.
Compared with prior art, the present invention has realized triple waterproof, has guaranteed that the sealing fully of cable conductor is filled, and avoids getting into the normal use that cable influences cable owing to the slit between sheath and the core causes aqueous vapor.Because the rubber material has better elastic, has improved the bending property of cable.The present invention has improved whole cable structurally waterproof performance, and electrical property and satisfactory mechanical property are economical and practical.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention.
Among the figure: copper conductor 1, interior semi-conductive layer 2, insulating barrier 3, outer semiconducting layer 4, the semi-conductive tape 5 that blocks water, aluminium-plastic tape 6, sheath 7, galvanized steel strip armour 8, rubber fills 9, sheath 10.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Referring to accompanying drawing 1, the disclosed this heavy in section of the present invention rubber is filled waterproof power cable, comprises three conductors that place the cable center position, and conductor is that the outer cover of 1, three conductor of copper conductor is equipped with sheath 7, galvanized steel strip armour 8 and sheath 10; Each copper conductor 1 outside also is set with interior semi-conductive layer 2, insulating barrier 3, outer semiconducting layer 4 successively, semi-conductive tape 5 blocks water.Be provided with rubber filling 9 between sheath 7 inside, three conductors; The most external of each conductor adopts aluminium-plastic tape 6 vertical bags.What insulating barrier 3 adopted is that the waterproof height of tree is pressed crosslinked polyethylene.Rubber fill 9 with sheath 7 co-extrusions, rubber fill 9 be covered with sheath 7 inside, copper conductor 1 between.
Disclosed cable is realized three layers of waterproof among the present invention: the insulating barrier 3 employing waterproof height of trees press crosslinked polyethylene, insulated wire cores to adopt aluminium-plastic tape 6 vertical bags, rubber filling 9 and plastics sheath 7 co-extrusions.Rubber is filled 9 and has been broken through the traditional handicraft that extruder has only plastics and plastics, rubber and rubber co-extrusion with plastics sheath 7 co-extrusions; The characteristics of extruding when utilizing the filling rubber not vulcanize; Plastics in the head and rubber runner are transformed; Adopt ∮ 200 plastic extruders and the shared head of ∮ 150 rubber extruding machines to realize rubber and plastic co-extrusion, guaranteed that like this sealing fully of cable conductor is filled.Guaranteed the rounding property of cable during co-extrusion, the filling sealing of carrying out cable conductor that can be effective, closely knit is avoided getting into the normal use that cable influences cable owing to the slit between sheath and the core causes aqueous vapor.
Claims (3)
