Abstract
The utility model relates to a longitudinal water-blocking cable extruded and filled by insulating, complex and shielding polyvinyl chloride of crosslinked polyethylene, which comprises core wires, an outer protective sleeve and a central filling strip, wherein each core wire comprises a conductor which is formed by twisting conductive single wire layers and is sequentially wrapped by a conductor shielding layer, a crosslinked polyethylene insulating layer, an insulating shielding layer, an insulating water-blocking strip layer, a copper wire spaced shielding layer, a copper strip spaced shielding layer and a shielding water-blocking strip layer, and a water-blocking object which comprises water-blocking cream and water-blocking powder is arranged among the conductive single wire layers. The utility mode improves the water-blocking performance, has particularly good longitudinal water-blocking performance and has small conductor resistance of the cable as compared with the prior similar products, good cable evenness and high production efficiency.
Description
Technical field
The utility model relates to a kind of power cable, especially has the power cable of good insulation, shielding, block-water performance.
Background technology
Existing power cable is provided with waterstop in order to strengthen block-water performance between every layer of monofilament of conductor, can cause the resistance of conductor to increase more like this; The gasket for packing that blocks water is set in cable core, can make the roundness of cable be difficult to guarantee like this, and production efficiency is low.
Summary of the invention
In order to overcome the deficiency of existing power cable, the utility model provides a kind of crosslinked polyetylene insulated composite shielding polyvinyl chloride extrusion packing cable that vertically blocks water.
The crosslinked polyetylene insulated composite shielding polyvinyl chloride extrusion packing that the utility model the provides cable that vertically blocks water, comprise heart yearn and oversheath, center packing, the conductor that every heart yearn is formed by the conductive monofilament layer-stranding and the conductor shield of outsourcing successively thereof, crosslinked polyetylene insulated layer, insulation screen, insulation water blocking tape layer, copper strips are dredged around screen, shielding water blocking tape layer and are constituted, and are provided with the water-blocking material of being made up of waterproof paste and water-proofing powder between each conductive monofilament layer.
In order to strengthen shielding properties of the present utility model, dredge around screen at insulation water blocking tape layer of the present utility model and the thin copper wire that between screen, is provided with of copper strips.
The beneficial effects of the utility model are: block-water performance improves, and especially vertically block-water performance is good, and the existing like product of the resistance ratio of the conductor of cable reduces; The roundness of cable is good; The production efficiency height.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
In Fig. 1,1, water-blocking material, 2, conductive monofilament, 3, conductor shield, 4, crosslinked polyetylene insulated layer, 5, the center packing, 6, insulation screen, 7, insulation water blocking tape layer, 8, copper wire is dredged around screen, and 9, copper strips dredges around screen, 10, the shielding water blocking tape layer, 11, oversheath, 12, heart yearn.
Embodiment
With reference to Fig. 1, make heart yearn 12 of the present utility model earlier: waterproof paste and water-proofing powder formation water-blocking material 1 are smeared in the surface of the every layer of conductive monofilament 2 except that outermost layer in the conductor, be twisted into conductor simultaneously, then outside conductor successively coating conductor screen 3, crosslinked polyetylene insulated layer 4, insulation screen 6, insulation waterstop 7, copper wire dredge around screen 8, copper strips and dredge around screen 9, shielding waterstop 10, make heart yearn 12.Again with three heart yearns 12 and stranded jointly at the center packing 5 with the polyvinyl chloride making of the center of three heart yearns 12 setting, stranded back adopts the polyvinyl chloride extruding to coat oversheath 11, circular oversheath 11 is tamped and forms in space between three heart yearns 12, promptly make the utility model.
Claims (2)
1, a kind of crosslinked polyetylene insulated composite shielding polyvinyl chloride extrusion packing cable that vertically blocks water, comprise heart yearn and oversheath, center packing, the conductor that every heart yearn is formed by the conductive monofilament layer-stranding and the conductor shield of outsourcing successively thereof, crosslinked polyetylene insulated layer, insulation screen, insulation water blocking tape layer, copper strips are dredged around screen, shielding water blocking tape layer and are constituted, and it is characterized in that being provided with the water-blocking material of being made up of waterproof paste and water-proofing powder between each conductive monofilament layer.
