Abstract
The utility model relates to a high-strength water resistant power cable, comprising a conductor, wherein a rubber layer is arranged outside the conductor, an insulation layer is arranged outside the rubber layer, a filling layer is arranged outside the insulation layer, the filling layer is internally provided with a high-strength filling rod, a composite water resistant layer is arranged outside the filling layer, the composite water resistant layer is composed of a buffer strip with a thickness of 1mm and a water resistant expansion strip with a thickness of 1mm, a liner layer is arranged outside the composite water resistant layer, a metal shielding layer is arranged outside the liner layer, and a cable sheath layer is arranged outside the metal shielding layer. The high-strength water resistant power cable disclosed by the utility model has a simple structure and good water resistance performance and is applicable to various occasions.
Description
Technical field
The utility model relates to a kind of power cable, is specifically related to a kind of waterproofing type cable.
Background technology
Power cable is the power transmission line that is used to transmit and distribute electric energy, be usually used in the underground electrical network in city, power station lead line, industrial and mining enterprises in-line power and cross river, the submarine transmission line in sea excessively, be specifically designed to the electric wire in places such as subway tunnel, light rail in addition.So often have moisture more or less inevitably laying the place, cross the river, excessively the sea power cable under water in addition all be immersed in the water, so strict to block-water performance.Existing power cable stop water generally is between insulating barrier and restrictive coating, to add one deck water blocking layer; This water blocking layer is to form so that waterstop is wrapped; But because the heat expansion of insulating material and metallic sheath material and shrinkage coefficient is inconsistent; Irrational bed course design can cause metallic sheath to be burst or metallic sheath not tight with contacting of waterstop, cause that vertical block-water effect is not good or the insulating surface electrical property is not good.Subway tunnel, light rail are with there being insulated wire cores in the construction of cable, the inner core of insulated wire cores, skin are insulating barrier, and there is outer jacket the insulated wire cores outside.When this cable uses; Owing to have water-proof function or water-proof function not bad,, and cause the insulation property reduction or the inefficacy of insulating barrier usually because of for a long time under wet environment or be immersed in the water and use; Produce the electric leakage accident, can not satisfy the normal use of occasions such as subway tunnel, light rail.
Summary of the invention
Goal of the invention: the purpose of the utility model is in order to overcome deficiency of the prior art, to provide a kind of simple in structure, and block-water performance is good, is applicable to the high strength waterproofing type power cable of various occasions.
Technical scheme: in order to solve the problems of the technologies described above, the described a kind of high strength waterproofing type power cable of the utility model, it comprises conductor; Outside said conductor, being provided with rubber layer, outside said rubber layer, being provided with insulating barrier, is packed layer outside said insulating barrier; In said packed layer, be provided with the high strength filler rod; Outside said packed layer, be provided with compound water blocking layer, said compound water blocking layer is made up of the buffer strip of 1mm and the zone of swelling that blocks water of 1mm, and outside said compound water blocking layer, is provided with inner covering; Outside said inner covering, be provided with metal screen layer, outside said metal screen layer, be provided with the cable cover(ing) layer.
Said inner covering is the polyethylene liner layer.
Said conductor is two, and is copper conductor.
Said high strength filler rod adopts the silicon carbide compound inserts.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model adopts the high strength filler rod that overall construction intensity is improved; Adopt compound water blocking layer, improved the block-water performance of cable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein:
1, conductor; 2, rubber layer; 3, insulating barrier; 4, packed layer; 5, high strength filler rod; 6, compound water blocking layer; 7, inner covering; 8, metal screen layer; 9, cable cover(ing) layer
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, the described a kind of high strength waterproofing type power cable of the utility model belongs to the power cable field, and it comprises conductor 1; Outside said conductor 1, being provided with rubber layer 2, outside said rubber layer 2, being provided with insulating barrier 3, is packed layer 4 outside said insulating barrier 3; In said packed layer 4, be provided with high strength filler rod 5, adopt high strength filler rod 5, improved integral intensity; Frangible is not damaged, and outside said packed layer 4, is provided with compound water blocking layer 6, and said compound water blocking layer 6 is made up of the buffer strip of 1mm and the zone of swelling that blocks water of 1mm; Adopt compound water blocking layer 6 single waterstop is wrapped before having solved and form problems such as the contact that brings is not tight; Improve the block-water performance of cable, be applicable to various occasions, outside said compound water blocking layer 6, be provided with inner covering 7; Outside said inner covering 7, be provided with metal screen layer 8, outside said metal screen layer 8, be provided with cable cover(ing) layer 9; Said inner covering 7 is the polyethylene liner layer; Said conductor 1 is two, and is copper conductor; Said high strength filler rod 5 adopts the silicon carbide compound inserts.The utility model is simple in structure, adopts the high strength filler rod that overall construction intensity is improved, and adopts compound water blocking layer, has improved the block-water performance of cable, adopts the silicon carbide compound inserts, and the environment-protecting asepsis evil meets green new concept.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
