Description
Technical field
The present invention relates to electric wire field, and in particular to a kind of anti-interference polyvinyl chloride insulation finer wire armour of resistance to compression tension
Fill power cable.
Background technology
At present, as office resident's floor more and more higher, coal mine machinery, automaticity improve constantly, electrical control
Technology has very important meaning in high-storey and coal production.Because normal throw is big, environment special, for fixing
The cable core and polychlorostyrene that the power cable that be used as power loop and protection circuit are laid in place is mainly made up of polyvinyl chloride insulation single line
Ethene oversheath forms, but the big environment used of cable normal throw is complicated, condition of work is severe and mobile frequent, uses the longevity
Life is not grown, and the region of methane accumulation is again extremely dangerous therefore not only very high to cable security requirement itself, and to frequently moving
Wearability, the anti-external tensile force performance requirement of dynamic field all-in-one cable are very high.
The content of the invention
In order to overcome the deficiencies in the prior art, there is provided a kind of anti-interference polyvinyl chloride insulation finer wire of resistance to compression tension
Armoured power cable.
To achieve the above object, the present invention, which provides, hands over a kind of anti-interference polyvinyl chloride insulation LWA light wire armoured electricity of resistance to compression tension
Power cable, including one group of pair twist aluminium alloy conductor, co-extrusion polyvinyl chloride insulation pipe forms insulated wire outside pair twist aluminium alloy conductor
Core, the wrapped first fine steel wire armor outside insulated wire cores, elastoplast body, elasticity modeling are externally provided with fine steel wire armor
Material is provided with the band that blocks water in vitro, and blocking water, band is externally provided with inner sheath, the wrapped second fine steel wire armor outside inner sheath, most
Afterwards cermet lining multiple tube is externally provided with cable.
Preferably, the elastoplast body and the band that blocks water are provided with high fire-retardance glass fiber tape, can also play fireproof
Effect.
Preferably, the inner sheath is woven into after pipe by alkali-free glass fibre band and is coated with organic high temperature-resistant silica gel through high temperature
Reason forms.
Preferably, described cermet lining multiple tube is made up of corundum ceramic, transition zone and steel respectively from inside to outside.
Compared with prior art, the beneficial effects of the present invention are：
1st, insulation uses polyvinyl chloride insulation pipe, instead of the structure that an existing conductor one insulate so that cable has preferable
Tension, compression strength.
2nd, armor is changed into LWA light wire armoured from common steel-tape armouring, relative to original insulation, fire resistance, shielding
Property, anti-interference, resistance to compression, tension, security performance improve 3-4 times.
3rd, using double-deck fine steel wire armor, the shielding and anti-interference of cable are enhanced.
4th, using elastoplast body so that cable has certain elasticity, anti-extrusion.
5th, the inner sheath be woven into by alkali-free glass fibre band after pipe be coated with organic high temperature-resistant silica gel through high-temperature process and
Into so that cable has the performances such as fire-retardant, heat-insulated, insulation, anti-electricity, softness, and it can be maintained in the case of subzero 54 degrees Celsius
Pliability, the sustainable work in the case of 260 degrees Celsius, reliably protecting is provided at 550 DEG C, anti-heat wave is resistant to≤1100 in short-term
The impact of DEG C high-temperature molten steel.
6th, outermost layer is provided with cermet lining multiple tube so that cable has good wear-resisting, heat-resisting, anti-corrosion and anti-machine
The combination property such as tool impact and thermal shock.
7th, the improvement of this cable, the service life of cable is not only extended, and there is very strong tensile strength, there is resistance
The advantages such as combustion performance is good, have a safety feature, shielding is good, anti-interference is good, make our product more have the market competitiveness；
With the increase of City Building and the density of population, the product has the wide market demand.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
The present invention rather than limitation the scope of the present invention, after the present invention has been read, those skilled in the art are each to the present invention's
The modification of the kind equivalent form of value falls within the application appended claims limited range.
As shown in figure 1, the present invention provides a kind of anti-interference polyvinyl chloride insulation LWA light wire armoured power cable of resistance to compression tension,
Including one group of pair twist aluminium alloy conductor 1, co-extrusion polyvinyl chloride insulation pipe 2 forms insulated wire cores outside pair twist aluminium alloy conductor,
Wrapped first fine steel wire armor 3, elastoplast body 4, elastoplast are externally provided with fine steel wire armor outside insulated wire cores
It is external to be provided with the band 5 that blocks water, inner sheath 7 is externally provided with the band that blocks water, the wrapped second fine steel wire armor 8 outside inner sheath,
Finally cermet lining multiple tube 9 is externally provided with cable.
In order that cable has more preferable fire resistance, the elastoplast body and the band that blocks water are provided with high fire-retardance glass fibers
Tie up band 6.
The inner sheath is woven into after pipe by alkali-free glass fibre band to be coated with organic high temperature-resistant silica gel and is formed through high-temperature process.
Described cermet lining multiple tube is made up of corundum ceramic, transition zone and steel respectively from inside to outside.
The present invention not only extends the service life of cable, and has very strong tensile strength, with fire resistance it is good,
Have a safety feature, the advantage such as shielding is good, anti-interference is good, make our product that more there is the market competitiveness；With city
The increase of building and the density of population, the product have the wide market demand.
