Abstract
The utility model discloses a kind of rodent-resistant cables, it is related to field of cable technology, common cable is solved the problems such as the weak anti-flammability shielding of moisture resistance is bad and cable is easy to be bitten broken by mouse, including multigroup core, every group of core includes the combination high intensity bundling belt of two cable cores of two cable cores and package, the cable core includes conductor and the semiconductive conductor shielding that is successively set on outside conductor, XLPE insulating layers, semi-conductive insulation shield and steel band insulation screen and restrictive coating, it is enclosed with water blocking layer successively outside multigroup core, inner sheath, armor, capsaicine figure layer, fire-retardant and oversheath；The shield effectiveness of the utility model cable is good compared with common cable, while the fire-retardant protection against rodents that blocks water, and further extends the service life of cable, reduces use cost.
Description
Technical field
The present invention relates to field of cables, more particularly to a kind of rodent-resistant cable.
Background technology
The application of cable is very wide, and common is mainly used in electric system, information transmission system etc., power information
Cable includes local cable, camera cable, light cable etc., and mouse is rodent, and tooth is grown all the life, daily must be with gnawing
The tooth of object abrasion fast-growth is stung to keep its physiological habit, and the distinctive smell of plastics makes plastics bite as muroid length
Object, mouse post the dark corner for staying in subterranean stream building more, and cable tunnel, groove, cable shaft etc. all become mouse
The best place inhabited, therefore these cables are often bitten by mouse, damaged by rats are current one of the main harm to cable, damaged by rats
Caused by cable destroy that be mainly outer protective sleeve will be worn cable is caused to intake, cause to have a power failure, communicating interrupt situations such as, damaged by rats is broken
It is bad to exclude difficulty, difficulty also is brought to maintenance work, currently, the poor flame retardant properties that block water of the cable of some, cable life is not
It is long.
Invention content
The present invention overcomes above-mentioned technical deficiency, provides a kind of waterproof, pull resistance fire-retardant, that prevent damaged by rats strong protection against rodents electricity
Cable.
The present invention specifically uses following technical scheme to achieve the goals above：
A kind of rodent-resistant cable, which is characterized in that including multigroup core, every group of core includes two cable cores and package two
The combination high intensity bundling belt of cable core, the cable core include conductor and the semiconductive conductor screen that is successively set on outside conductor
It covers, XLPE insulating layers, semi-conductive insulation shield and steel band insulation screen and restrictive coating, resistance is enclosed with successively outside multigroup core
Water layer, inner sheath, armor, capsaicine figure layer, fire-retardant and oversheath.
Further, the gap in water blocking layer is provided with filling line, and core is three groups, and three groups of cores are at circumference
It is evenly arranged.
Further, the thickness of the inner sheath is the PE materials of 2 ~ 4mm, and oversheath is that thickness is 4 ~ 6mm polychlorostyrene second
Alkene material.
Further, the armor is twisted again by a diameter of 0.15 ~ 0.2mm zinc-coated wires.
Further, the material of the flame-retardant layer is low smoke and low halogen material.
The material of the flame-retardant layer is low smoke and low halogen material, primarily directed to polyvinyl chloride chlorosulfonated polyethylene two
The discharge that calcium carbonate and zinc borate etc. can reduce the hydrogen chloride of flame-proof polyvinyl chloride is added in kind material in poly- record ethylene formula
Amount and smoke amount reduce the discharge capacity of halogen, acid mist, smog to improve Flame Retardancy.
Beneficial effects of the present invention are as follows：
1. can bite capsaicine figure layer after mouse son gnaws through oversheath, capsaicine generates strong impulse to mouse, drives
Mouse is set to abandon biting, even if capsaicine figure layer will be worn, the armor of the inside further prevents mouse from further biting cable,
To protect cable by damaged by rats.
2. the dry filling oxidant layer of water blocking layer, expansion waterproofing rope layer, radial moisture-proof layer is triple blocks water, waterproof moisture-proof effect
It is good.

Specific implementation mode
In order to which those skilled in the art are better understood from the present invention, below in conjunction with the accompanying drawings with following embodiment to the present invention
It is described in detail.
Embodiment
As shown in Figure 1, the present invention provides a kind of rodent-resistant cables, which is characterized in that including multigroup core 1, every group of cable
Core wire 1 includes that combination high intensity the bundling belt 1-2, the cable core 1-1 of two cable core 1-1 of two cable core 1-1 and package includes
Conductor 1-1.1 and semiconductive conductor shielding, XLPE insulating layers, the semi-conductive insulation shield being successively set on outside conductor 1-1.1
With steel band insulation screen and restrictive coating 1-1.2, be enclosed with successively outside multigroup core 1 water blocking layer 2, inner sheath 3, armor 4,
Capsaicine figure layer 5, flame-retardant layer 6 and oversheath 7.
Gap in water blocking layer 2 is provided with filling line 8, and three groups of cores 1 are arranged at even circumferential.
The thickness of the inner sheath 3 is the PE materials of 2 ~ 4mm, and oversheath 7 is that thickness is 4 ~ 6mm pvc materials.
The armor 4 is twisted again by a diameter of 0.15 ~ 0.2mm zinc-coated wires.
The material of the flame-retardant layer 6 is low smoke and low halogen material.
The above, only presently preferred embodiments of the present invention, are not intended to limit the invention, patent protection model of the invention
It encloses and is subject to claims, equivalent structure variation made by every specification and accompanying drawing content with the present invention, similarly
