The insulating high-voltage power cable has the characteristics of good water-blocking performance, high corrosion resistance, high oxidation resistance, high heat resistance and the like, and is free of mechanical damage.
Description
Technical field
The present invention relates to field of cables, specifically a kind of Insulating A High-Voltage power cable.
Background technology
With skyrocketing for copper valency, the price difference of copper aluminum is increasing, and power industry has started to the use for paying close attention to aluminium conductor.China
The current common situation of cable industry is only 5～16 mm2Conductor adopts solid conductor, and 25 mm2Stranded conductor is adopted above.
In the manufacturing process of traditional aluminium core conductor, it is aluminium bar to need through aluminium ingot drawing, and it is aluminum list that aluminium bar is drawn through drawing process
Line, aluminum single line are stranded for molding conductors such as circular or sector, shoes again, and in order to reduce gap between conductor single line, improve and hinder
Aqueouss energy, conductor often also need to be pressed.This stranded conductor has following open defect：（1）Aluminum is easily aoxidized, and reduces leading
Body performance, affect service life, aluminum single line and the loaded down with trivial details course of processing, increase with air, the contact surface of mechanical greasy dirt and
Exposure level, therefore easily aoxidize；（2）Complex procedures, the course of processing are loaded down with trivial details, and equipment is more, take production and memory space is big,
Organization of production difficulty is big, low production efficiency, high energy consumption, and cost of labor is high, increases logistics loss and quality control risk；（3）
The increase of the course of processing, easily causes the mechanical damage on its surface, and surface discharge phenomena, reprocessabilty can be caused also to increase
The thermal stress of conductor, makes conductor be hardened, and reduces the electric conductivity of conductor；（4）Between stranded conductor, gap is big, block-water performance drop
It is low；（5）Conductor and the outside diameter of cable are increased, occupancy lays space.
The content of the invention
The present invention is in order to solve problems of the prior art, there is provided a kind of block-water performance is good, corrosion-resistant, oxytolerant
Change, heat-resist High-Voltage Insulation power cable.
A kind of Insulating A High-Voltage power cable of the present invention, including the solid aluminium conductor positioned at cable center, solid
Four piece sector first solid aluminum molded line, then the second solid aluminum molded line that extrude annular are extruded outside aluminium conductor first；In the second aluminium profiles line
Low Density Polyethylene insulating barrier is extruded outward, wrapped double-deck waterstop is overlapped, in waterstop external welding corrugated aluminum sheath, and in wrinkle
Colophonium is coated on aluminium sheath, finally medium density polyethylene oversheath is extruded in cable outermost layer.
Further improve, the shape size of four pieces of described sector the first solid aluminum molded line is identical.
Compared with prior art, the beneficial effects of the present invention is：
1st, the present invention has preferably ensured air-tightness and cable bend using argon arc welding wrinkle aluminum as radial water-resisting structure
Can, using the expansion band that blocks water as longitudinal water-blocking structure, with reference to corrugated aluminum sheath, the double shield block-water performance of cable.
2nd, the present invention is overlapped around waterstop of double-baging so that conductor has very strong water stop function, will not soak because of moisture
Enter to cause oxidation, the corrosion of conductor, so as to affect the electrical property of cable, or even abnormal broken line accident occurs；Medium density polyethylene
Separation sleeve, oversheath, while protection cable, also play further waterproof action.
3rd, thicker wire, argon arc welding wrinkle aluminum can also play preferable drawing-resistant function, with stronger external force collision work(
Energy.
4th, using solid molding aluminium conductor, technological process is simplified, improves surface quality and electrical property, block-water performance
Good, Stability Analysis of Structures, external diameter are little.
5th, conductor coats continuous extruder using aluminum, and an extrusion molding after softening improves surface quality and electrical property,
Cannot be easily caused the mechanical damage on its surface and cause surface discharge phenomena, the heat that because of reprocessabilty, will not increase conductor should
Power, makes conductor be hardened, and reduces the electric conductivity of conductor；As four pieces of first solid aluminium profiles of sector are first first extruded outside solid aluminium conductor
Line, then the second solid aluminum molded line of annular is extruded, so that the machinery of aluminium conductor, electric property are significantly larger than traditional handicraft adding
The performance of the aluminium conductor of work.
6th, solid aluminum molded line excellent heat resistance, safety and reliability are good, long service life.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
A kind of Insulating A High-Voltage power cable as shown in Figure 1, including the solid aluminium conductor 1 positioned at cable center, solid
Four block-shaped size identical sector first solid aluminum molded line 2, then the second solid aluminium profiles that extrude annular are extruded outside aluminium conductor first
Line 3；Low Density Polyethylene insulating barrier 4 is extruded outside the second aluminium profiles line, wrapped double-deck waterstop 5 is overlapped, in waterstop external welding
Corrugated aluminum sheath 6, and Colophonium 7 is coated on corrugated aluminum sheath, finally medium density polyethylene oversheath is extruded in cable outermost layer
8。
Concrete application approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, it is noted that for
For those skilled in the art, under the premise without departing from the principles of the invention, some improvement can also be made, this
A little improvement also should be regarded as protection scope of the present invention.
