Abstract
A kind of new corrosion resistant cable of this practicality.This utility model includes insulated wire cores, it is characterized in that：Sheath is provided with outside described insulated wire cores, described sheath is provided with one group of tension axially outside and splits reinforcement, layer of metal screen layer is wrapped up on the outside of described sheath, insulating layer of asbestos is provided with outside described metal screen layer, aluminium foil layer is provided with outside described insulating layer of asbestos, between described sheath and described metal screen layer, obturator is provided with.This utility model has the characteristics such as heat radiation, cold-resistant, acid and alkali-resistance and corrosive gas, waterproof.
Description
Technical field：
This utility model is related to a kind of corrosion proof cable, belongs to field of cables.
Background technology：
XLPE is cable cover(ing) more conventional at present, and in XLPE cable, although oversheath is the material of higher density, but
Its water resistance imperfection, the process that any PVC, PE sheath is progressively permeated after all there is immersion, this process is in bad water
In the case of matter（Acid or aqueous slkali, chloride, Organic substance corrosive liquid etc.）Can drastically accelerate, cause electrolysis and chemical attack, finally
Cause insulation breakdown.Transition joint of the structure far away from cable body, is more vulnerable to infringement.Therefore cable anti-corrosion work must be carried out
Make.
The corrosion of cable typically refers to the corrosion of cable metal sheath, and the corrosion of cable is drawn by stray electrical current and chemical action
Rise, its corrosion is slowly carried out, and protective metal shell is corroded all in oversheath sheath, be typically difficult to find, so must
Must arouse attention.
The corrosion that alternating current causes is not serious, and the root for producing electrolytic etching is from big spuious of DC equipment person who lives in exile
Electric current, than more serious if the cable corrosion that the stray electrical current of electric railway person who lives in exile's the earth causes.Produce the original of chemical attack
Because a lot, mainly there are two kinds：One kind be cable in the fabrication process, as the outer jacket materials of protective metal shell are improper, it is right to include
The mordant material of protective metal shell；Another kind is that surrounding is bad caused, such as contains acid, alkali, the organic corruption of chlorination in soil
Erosion thing etc..In manufacturing enterprise always, the corrosion of cable or cracking will cause short circuit, so as to initiation fire.
Utility model content：
The purpose of this utility model is to provide a kind of corrosion proof cable for above-mentioned problem, with heat radiation,
The characteristic such as cold-resistant, acid and alkali-resistance and corrosive gas, waterproof, the construction of cable are soft, and radiation is convenient, under high temperature (high and cold) environment electrically
Stable performance, ageing resistace are projected, long service life, are widely used in the row such as metallurgy, electric power, petrochemical industry, electronics, automobile making
Industry.
Above-mentioned purpose is realized by following technical scheme：
Corrosion resistant cable, including insulated wire cores, are provided with sheath, on the outside of described sheath outside described insulated wire cores
It is axially disposed to have one group of tension to split reinforcement, layer of metal screen layer, described metallic shield are wrapped up on the outside of described sheath
Layer is outside to be provided with insulating layer of asbestos, and aluminium foil layer, described sheath and described gold are provided with outside described insulating layer of asbestos
Obturator is provided between category screen layer.
Described corrosion resistant cable, described insulation core wire include conductor and the insulating barrier being wrapped in outside conductor.
Described corrosion resistant cable, is provided with inside the space of described insulation core wire inside described sheath and fills out
Fill bar.
Described corrosion resistant cable, is provided with corrosion-inhibiting coating on described metal screen layer.
Beneficial effect：
Outside of the present utility model is provided with aluminium foil layer, plays preferable antiseptic effect, and the setting of insulating layer of asbestos is caused
Cable can be well isolated from heat radiation, on metal screen layer the setting of corrosion-inhibiting coating cause cable can be good at acid and alkali-resistance and
Corrosion-resistant, this utility model has the characteristics such as heat radiation, cold-resistant, acid and alkali-resistance and corrosive gas, waterproof, and the construction of cable is soft
Soft, radiation is convenient, and under high temperature (high and cold) environment, electric property is stable, and ageing resistace is projected, and long service life is widely used in smelting
The industries such as gold, electric power, petrochemical industry, electronics, automobile making.

Specific embodiment：
Embodiment 1：
As shown in figure 1, the corrosion resistant cable of the present embodiment, including insulated wire cores, arrange outside described insulated wire cores
There is sheath 1, described sheath is provided with one group of tension axially outside and splits reinforcement 2, one layer of parcel is golden on the outside of described sheath
Category screen layer 3, is provided with insulating layer of asbestos 4, is provided with aluminum outside described insulating layer of asbestos outside described metal screen layer
Layers of foil 5, is provided with obturator 6 between described sheath and described metal screen layer.
Corrosion resistant cable described in the present embodiment, described insulation core wire include conductor 7 and are wrapped in outside conductor
Insulating barrier 8.
Corrosion resistant cable described in the present embodiment, inside described sheath in the space of described insulation core wire
Face is provided with packing 9.
Corrosion resistant cable described in the present embodiment, is provided with corrosion-inhibiting coating on described metal screen layer.
Technological means disclosed in this utility model scheme are not limited only to the technological means disclosed in above-mentioned technological means, also
Including the technical scheme being made up of above technical characteristic equivalent.Unaccomplished matter of the present utility model, belongs to this area skill
The common knowledge of art personnel.
