Abstract
The invention discloses a kind of flame retardant cable, it is related to field of cable technology, it is bad and the problems such as cable is easily bitten broken by mouse in the weak anti-flammability of moisture resistance to solve common cable, including a plurality of cable, every cable includes conductor and the loose jacket layer being arranged on outside conductor, aramid yarn layer is disposed with outside a plurality of core, inner sheath, plastic-coated steel belt layer, flame-retardant layer, capsaicine figure layer, oversheath and anticorrosive coat, fire-resisting ceramic silicone rubber is filled with aramid yarn layer internal voids, metallic strength member is provided with a plurality of cable center, the material of oversheath is low-smoke halogen-free polyolefin；The tensile strength of cable of the present invention compared with common cable, while the fire-retardant protection against rodents that blocks water, the service life of cable is further extended, reduce use cost.
Description
Technical field
The present invention relates to field of cables, more particularly to a kind of flame retardant cable.
Background technology
The application of cable is very wide, and common is mainly used in power system, information transmission system etc., power information
Cable includes local cable, camera cable, light cable etc., and mouse is rodent, and tooth grows 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 turn into muroid length to bite
Object, post the dark corner for staying in subterranean stream building, cable tunnel, groove, cable shaft etc. all becomes mouse to mouse more
The best place inhabited, therefore these cables are often bitten by mouse, damaged by rats is currently to one of main harm of cable, damaged by rats
Caused by cable to destroy be mainly that outer protective sleeve will be worn and cause cable 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, at present, the poor flame retardant properties that block water of the cable of some, cable life is not
It is long.
The content of the invention
The present invention overcomes above-mentioned technical deficiency, there is provided the strong fire-retardant electricity of a kind of waterproof, pull resistance that is fire-retardant, preventing damaged by rats
Cable.
The present invention specifically uses following technical scheme to achieve these goals：
A kind of flame retardant cable, including a plurality of cable, every cable includes conductor and the loose jacket layer being arranged on outside conductor, more
Aramid yarn layer, inner sheath, plastic-coated steel belt layer, flame-retardant layer, capsaicine figure layer, oversheath and anti-corrosion are disposed with outside bar core
Layer, fire-resisting ceramic silicone rubber is filled with aramid yarn layer internal voids, is provided with metallic strength member at a plurality of cable center, outside
The material of sheath is low-smoke halogen-free polyolefin.
Further, described conductor is copper conductor, and the copper wire that conductor is a diameter of 0.3mm and 0.1mm presses 1:2 uniform cloth
Put.
Further, plastic-coated steel belt layer is that the galvanized steel strip that thickness is 1.2~3.6mm is entwined, on galvanized steel strip
The even radiating aperture for being provided with a diameter of 320~560um.
Further, the reinforcement cable core is twisted again by a diameter of 0.15~0.2mm zinc-coated wires forms.
Further, the flame-retardant layer includes copper mesh, expanded granular layer, the mica layer set gradually from inside to outside, institute
It is 0.25-0.63mm to state mica layer thickness, and the filament diameter of the copper mesh is 0.21-0.98mm.
Further, anticorrosive coat is the bitumen layer that thickness is 0.12~0.35mm.
Beneficial effects of the present invention are as follows：
1. can bite capsaicine figure layer after mouse son gnaws through oversheath, capsaicine produces 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,
So as to protect cable to play good fireproof flame-retardant effect by damaged by rats, the setting of flame-retardant layer.
2. water blocking layer dry filling oxidant layer, expansion waterproofing rope layer, radial direction moisture-proof layer is triple blocks water, waterproof moisture-proof effect
It is good.
Brief description of the drawings
Fig. 1 is a kind of structural representation of flame retardant cable of the present invention.
Embodiment
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 examples to the present invention
It is described in detail.
Embodiment 1
As shown in figure 1, the present embodiment provides a kind of flame retardant cable, including a plurality of cable 2, every cable 2 include conductor 2-1
With the loose jacket layer 2-2 being arranged on outside conductor 2-1, a plurality of core 2 is disposed with aramid yarn layer 4, inner sheath 5, plastic-coated outside
Steel belt layer 6, flame-retardant layer 7, capsaicine figure layer 8, oversheath 9 and anticorrosive coat 10, ceramic is filled with the internal voids of aramid yarn layer 4
Fire-resistant silicon rubber 3, metallic strength member 1 is provided with a plurality of center of cable 2, the material of oversheath 9 is low-smoke halogen-free polyolefin.
In the present embodiment, capsaicine figure layer can be bitten after mouse son gnaws through oversheath, capsaicine produces strong to mouse
Stimulation, drive mouse to abandon biting, even if capsaicine figure layer will be worn, the armor of the inside further prevents mouse further
Bite cable, so as to protect cable to play good fireproof flame-retardant effect by damaged by rats, the setting of flame-retardant layer.
Embodiment 2
The present embodiment is further optimized on the basis of embodiment 1, is specifically：
Described conductor 2-1 is copper conductor, the copper wire that conductor 2-1 is a diameter of 0.3mm and 0.1mm presses 1:2 uniform cloth
