Description
Technical field
The utility model relates to a kind of outdoor power cables of resistance to worm, relate generally to field of cables.
Background technique
Cable is usually by several or several groups of conducting wires (every group at least two) are twisted, mutually insulated between every group of conducting wire,
It is usually twisted into around a center, entire outside is surrounded by the coating of high-insulation, is mounted in underground, the bottom more or is erected at sky
In, it is used for telecommunication or power Transmission.Cable is open air using usually setting environment, and open air possesses various rugged environments, such as
The biting of mouse worm ant, the invasion of ultraviolet irradiation, extreme misery etc., will all test cable, therefore be set to the property of outdoor cable
Can be more demanding, traditional cable is generallyd use equipped with several protective layers, and then plays the invasion of exclusion of water fireworm ant, this side
Case can make cable become very heavy, be unfavorable for the arrangement of cable.
Utility model content
For the above the deficiencies in the prior art, the utility model proposes a kind of outdoor power cables of resistance to worm, can be according to ring
Feature autonomous Design this section of cable in border needs the main performance having.
To achieve the above purpose, the technical solution of the present invention is: including from inside to outside successively including: conductor, partly leading
Electric waterstop, shielding copper strips, the first low smoke and low halogen band, high fire-retardance liner layer, brass band, low smoke and zero halogen glass wool cloth band,
Separation sleeve and oversheath, the separation sleeve are equipped with several annular cavities, and several annular cavities are uniform along core of a cable direction
Distribution, at least provided with two feed openings, the feed opening passes through oversheath and extends to outer wall each annular cavity, described to add
Material mouth is jammed rubber stopper.
It the technical principle of the utility model and has the beneficial effect that: being equipped with annular cavity in separation sleeve.Can will wherein from
Group addition kills mouse, termiticide or even the pulvis put out a fire, annular cavity two feed openings of setting are more convenient to add powder thereto
Agent sufficiently loads, while the jammed setting rubber stopper of feed opening, when by high temperature, internal gas expansion, can automatically by
Rubber stopper sprays pressure release, if wherein loading fire extinguishing pulvis can also put out a fire.Annular cavity is mutually indepedent, therefore the function of cable
Interim autonomous Design can be needed according to the later period, the environment used more has specific aim, and the occasion addition that fire has occurred is gone out
Fiery pulvis, occasion addition rat poison mousy etc..
Further, the conductor is the structure that is twisted of the tin plating flexible conductor of multiply, improves whole toughness and anticorrosive
Performance.
Further, shielding copper strips is the circumferentially uniformly distributed copper wire of crosslinked polyetylene insulated layer, can be homogenized the electricity of conductive surface
, prevent internal field from concentrating and discharging.
Further, the separation sleeve is that the polythene material of bad hydraulic permeability extrudes to be formed, and improves whole waterproof performance.
Further, termiticide raticide and fire extinguishing pulvis are arranged in a crossed manner in the annular cavity, while having both fire extinguishing and termiticide mouse
Effect.
Further, the oversheath is that low-smoke non-halogen flame-retardant mixes rubber, and Halogen is safe and non-toxic.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Attached drawing needed in description is briefly described, it should be apparent that, the accompanying drawings in the following description is only that this is practical new
Wherein two width of type for those of ordinary skill in the art without any creative labor, can be with root
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Wherein, 1- conductor, 2- semiconductor waterstop, 3- shielding copper strips, the first low smoke and low halogen of 4- band, in 5- high fire-retardance
Lining, 6- brass band, 7- low smoke and zero halogen glass wool cloth band, 8- separation sleeve, 9- oversheath, 10- annular cavity；11- rubber stopper.
Specific embodiment
Below in conjunction with attached drawing, the technical solution in the utility model is clearly and completely described, it is clear that retouched
The embodiment stated is only the preferred embodiment of the utility model, instead of all the embodiments.Based in the utility model
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the range of the utility model protection.
Embodiment
As shown in Figure 1, the utility model embodiment includes from inside to outside successively including: conductor 1, semiconductor waterstop 2, screen
Cover copper strips 3, the first low smoke and low halogen band 4, high fire-retardance liner layer 5, brass band 6, low smoke and zero halogen glass wool cloth band 7, separation sleeve 8
With oversheath 9, the separation sleeve 8 be equipped with several annular cavities 10, can will wherein from group addition kill mouse, termiticide even put out a fire
Pulvis, two feed openings are arranged in an annular cavity 10, more convenient to add pulvis thereto, sufficiently load several annulars
Inner cavity 10 is uniformly distributed along core of a cable direction, and each annular cavity 10 is at least provided with two feed openings, the feed opening
Outer wall is extended to across oversheath 9, the feed opening is jammed rubber stopper 11.When by high temperature, internal gas expansion,
Rubber stopper 11 can be sprayed into pressure release automatically, if wherein loading fire extinguishing pulvis can also put out a fire.
The conductor 1 is the structure that the tin plating flexible conductor 1 of multiply is twisted, and improves whole toughness and corrosion resistance.
Shielding copper strips 3 is the circumferentially uniformly distributed copper wire of crosslinked polyetylene insulated layer, can be homogenized the electric field on 1 surface of conductor, prevent local electricity
It concentrates and discharges in field.Improve whole waterproof performance.Termiticide raticide and fire extinguishing pulvis are arranged in a crossed manner in the annular cavity 10, together
