Description
Technical field
The utility model is related to electric wire field, and in particular to a kind of copper core cross-linked polyethylene insulated steel wire armored blocks water
Power cable.
Background technology
With the progress and the development of society of science and technology, numerous Business groups, skyscraper, place of public amusement, subway
And underground street etc. continues to bring out, its power consumption grows with each passing day, and the kind and consumption of all kinds of cables also accordingly increase.But it is common
Cable can not simultaneously bear mechanical external force and carry out effective waterproof, in many important events, once cable sustains damage or enters
When water results in the systems such as power supply, communication and cannot run or even accident occurs, make troubles to normal social life.
Mechanically damaged in order to prevent, power cable forms armored cable in outer layer armored protective layer.Cable adds armour
The purpose of dress layer passes through screen in addition to strengthening the mechanical protections such as tensile strength, compression strength and increasing the service life, more importantly
Cover protection improve cable interference free performance, also can in case pound, press, rack after cable sheath damage core cause short circuit.Also
New problem：One is blocking water for armored cable, and water is the primary factor for affecting cable security performance, and steam is once entered in cable
Portion, the triumphant insulation crosslinked polyethylene up to cable easily produces water tree, and the service life of cable will be substantially reduced；Two is pulse electricity
The impact to insulating is pressed, the frequency range of variable-frequency power sources is relatively wide, but its waveform is the frequency band profile of a basic frequency, is contained
Many higher hamonic waves, amplitude is also larger, and this harmonic wave can feed through to cable, it is possible to cause cable breakdown.
Utility model content
In order to overcome the deficiencies in the prior art, there is provided a kind of copper core of multiple stop water is crosslinked polyetylene insulated
Wire armoring water-resistant power cable.
For achieving the above object, the utility model provides a kind of copper core cross-linked polyethylene insulated steel wire armored and blocks water electric power electricity
Cable, including cable core, described cable core is formed by many cores are stranded；Waterproofing rope is filled in cable core gap, it is outer wrapped in cable core
First waterstop, outside the first waterstop inner sheath is extruded, and in outer wrapped second waterstop of inner sheath, is compiled outside the second waterstop
Steel wire armor layer is knitted, then in outer wrapped 3rd waterstop of steel wire armor layer, finally extrudes oversheath in cable outermost layer；Described
Core includes copper conductor, first directly drags water blocking yarn to overlap wrapped semiconductive again outside copper conductor and blocks water band, blocks water bundle in semiconductive
Band extrudes respectively internal shield, insulating barrier and external shielding layer in three-layer co-extruded mode outward, then wrapped partly leads external shielding layer is outer
Electric waterstop, finally weaves shielding layer of copper wires outside semiconductor waterstop.
Preferably, when the conductor is formed by 1+6 root copper wires are stranded, copper wire interlayer puts down the waterstop for dragging vertical bag 10mm wide.
Preferably, when the conductor is formed by 6+12 root copper wires are stranded, copper wire interlayer puts down the waterstop for dragging vertical bag 25mm wide.
Preferably, when the conductor is formed by 12+18 root copper wires are stranded, copper wire interlayer is put down to drag vertical bag 40mm is wide and is blocked water
Band.
Preferably, when the conductor is formed by 18+23 root copper wires are stranded, copper wire interlayer is put down to drag vertical bag 60mm is wide and is blocked water
Band.
The beneficial effects of the utility model are：
Compared with prior art, the utility model such as employs that core blocks water, cable core blocks water, blocks water outside cable core at multiple the blocking water
Structure, not only can effectively prevent steam from entering inside cable, be exactly rainwater weather, and water all cannot be introduced in cable, so as to extend
The service life of cable；Construction of cable symmetrical balance, can eliminate impact of the pulse voltage to cable insulation, prevent insulating barrier quilt
Puncture；The metal screen layer of cable, uses but also as the neutral conductor, saves material cost.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is further elucidated, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limit scope of the present utility model, after the utility model has been read, art technology
Modification of the personnel to the various equivalent form of values of the present utility model falls within the application claims limited range.
As shown in figure 1, the utility model provides a kind of copper core cross-linked polyethylene insulated steel wire armored water-resistant power cable, bag
Include cable core, described cable core is formed by many cores are stranded；Waterproofing rope 9 is filled in cable core gap, in cable core outer wrapped first
Waterstop 10, extrudes inner sheath 11 outside the first waterstop, in outer wrapped second waterstop 12 of inner sheath, takes probability and is not less than
20%, in the outer braided steel wire armor 13 of the second waterstop, then in outer wrapped 3rd waterstop 14 of steel wire armor layer, take probability not
