Description
Technical field
The present invention relates to electric wire field, be specifically related to a kind of copper core crosslinked polyetylene insulated waterproof termite-proof electric power electricity
Cable.
Background technology
When cable uses in the environment such as industry, business, shipbuilding industry, skyscraper, mine, oil, chemical industry, it is not only subject to
To the damage of non-artificial mechanical external force, also corroded by Mus, Coptotermes formosanus Shtrari., worm-eaten, and the prestige when combustible and explosive area or fire
The side of body, to the public place of personal safety as well as the property safety, residential building, market, garden, has strict restriction to the place of electric power system, not only limits
Make the termite-resistant rodent-resistant fire protecting performance of cable, also limit cable laying space and cable radical, because cable laying space is more
Little, the cable radical so laid is the fewest, and safety coefficient is the highest.Existing technical matters uses natural butylbenzene in terms of material
Glue makees and insulate and sheath.Natural rubber is apolar substance, easily dissolves in greasy dirt, and low (the insulation volume electricity of insulation resistance
Resistance rate 1011), bad mechanical property, butadiene-styrene rubber insulating properties are poor, and physical property is unstable, varies with temperature and has large change,
So its protection against rodents, termite-proof, worm resistance can be poor；
Tradition termite-resistant rodent-resistant cable production technology process there is problems in that 1, the poor performance of material own causes insulating properties, machine
Tool poor performance；2, insulation and sheath poor flexibility, compression is big, and intensity is low；3, protection against rodents, termite-proof, worm resistance can be poor；4, resistance to
Climacteric, heat-proof aging, tolerance to cold is poor；Water preventing ability is poor, and water is the primary factor affecting cable security performance, and steam once enters
Inside cable, the insulation crosslinked polyethylene of cable easily produces water tree, and the service life of cable will be substantially reduced；5, existing
In technology, great majority are all to use aluminium-plastic tape, softer, not hard so that cable is easy to fracture.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is provided that a kind of crosslinked polyetylene insulated waterproof termite-proof electric power of copper core
Cable.
For achieving the above object, the present invention provides a kind of crosslinked polyetylene insulated waterproof Anti-termite power cable of copper core, bag
Include conductor, outside conductor, extrude crosslinked polyetylene insulated layer, the overlapping wrapped one side waterstop of the outer dextrad of crosslinked polyetylene insulated layer, single
The outer lapped shielding layer of face waterstop, the overlapping wrapped non-woven fabrics of the outer dextrad of screen layer, outside non-woven fabrics, extrude separation sleeve, at separation sleeve
Outer first indulge bag embossing compound copper-plastics band after wrapped two-sided waterstop, finally, cable outermost layer extrudes the termite-proof oversheath of HDPE.
Preferably, described conductor is for pressing circular copper conductors.
Preferably, described separation sleeve is PVC inner sheath.
Preferably, described screen layer forms for double-deck copper strips left-hand overlap is wrapped.
The beneficial effects of the present invention is:
Compared with prior art, present invention employs waterstop and non-woven fabrics double water-resistance structure, not only can effectively prevent steam
Inside entrance cable, it is simply that rainwater weather, water all cannot be introduced in cable, thus extends the service life of cable；Use and hand over
Connection polyethylene insulation, good mechanical property；This cable insulation and sheath good springiness, compression are little, and intensity is high, and rat-and-ant proof is strong；
Screen layer uses the vertical copper-clad band structure of bilayer, strengthens shield effectiveness, strengthens the mechanical performance of cable, and isolation electromagnetic field is done
Disturb；Use one side and two-sided waterstop so that the block-water effect of cable is more preferable；Compound copper-plastics band is used to replace aluminium-plastic tape,
Relatively hard so that cable more stiffened, is difficult to extruding and fractures.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate
The present invention rather than limit the scope of the present invention, after having read the present invention, each to the present invention of those skilled in the art
The amendment planting the equivalent form of value all falls within the application claims limited range.
As it is shown in figure 1, the present invention provides a kind of crosslinked polyetylene insulated waterproof Anti-termite power cable of copper core, including conductor
1, extrude crosslinked polyetylene insulated layer 2 outside conductor, the overlapping wrapped one side waterstop 3 of the outer dextrad of crosslinked polyetylene insulated layer, monolayer
Averagely taking probability 15%-20%, minimum takes probability not less than 5%；The outer lapped shielding layer 4 of one side waterstop, the outer dextrad of screen layer is overlapping
Wrapped non-woven fabrics 5, extrudes separation sleeve 6 outside non-woven fabrics, wrapped two-sided resistance after first indulging bag embossing compound copper-plastics band 7 outside separation sleeve
Water band 8, extrudes the termite-proof oversheath of HDPE 9 outside last cable, effectively prevent the Coptotermes formosanus Shtrari. destruction to cable, just affecting cable
Often work.
In order to improve electric conductivity further, described conductor is for pressing circular copper conductors.
In order to make cable have more preferable flexibility, bendability, described separation sleeve is PVC inner sheath.
In order to improve the shield effectiveness of cable, described screen layer is indulged bag for double-deck copper strips left-hand overlap and is formed, vertical bag than around
The water preventing ability of bag is more preferable.
The above is only the preferred embodiment of the present invention, it is noted that come for those of ordinary skill in the art
Saying, under the premise without departing from the principles of the invention, it is also possible to make some modification and improvement, these also should be regarded as belonging to the present invention
Protection domain.
