Description
Technical field
The utility model is related to electric wire fields, and in particular to a kind of thin steel of anti-interference polyvinyl chloride insulation of resistance to compression tension
Wire armoured power cable.
Background technology
At present, as office resident's floor is higher and higher, coal mine machinery, the degree of automation are continuously improved, electrical control
Technology has very important meaning in high-storey and coal production.Since normal throw is big, environment special, for fixing
Place laying is used as power the cable core that is mainly made of polyvinyl chloride insulation single line of power cable and polychlorostyrene of circuit and protection circuit
Ethylene oversheath forms, but the big environment used of cable normal throw is complicated, operating condition 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, but also to frequently moving
Wearability, the anti-external tensile force performance requirement of dynamic field all-in-one cable are very high.
Utility model content
In order to overcome the deficiencies in the prior art, provide a kind of resistance to compression tension anti-interference polyvinyl chloride insulation finer wire
Armoured power cable.
To achieve the above object, the utility model, which provides, hands over a kind of anti-interference polyvinyl chloride insulation finer wire armour of resistance to compression tension
Power cable is filled, including one group of pair twist aluminium alloy conductor, co-extrusion polyvinyl chloride insulation pipe forms exhausted outside pair twist aluminium alloy conductor
Edge core, the wrapped first fine steel wire armor outside insulated wire cores, elastoplastic body, bullet are externally provided in fine steel wire armor
Property plastic body is externally provided with the band that blocks water, and is externally provided with inner sheath in the band that blocks water, the wrapped second fine steel wire armouring outside inner sheath
Layer, is finally externally provided with cermet lining multiple tube in cable.
Preferably, the elastoplastic body and the band that blocks water can also play fireproof equipped with high fire-retardance glass fiber tape
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
It manages.
Preferably, the cermet lining multiple tube is made of from inside to outside corundum ceramic, transition zone and steel respectively.
Compared with prior art, the beneficial effects of the utility model are：
1st, insulation is using polyvinyl chloride insulation pipe, the structure to insulate instead of an existing conductor one so that cable has
Preferable tension, compression strength.
2nd, armor becomes LWA light wire armoured from common steel-tape armouring, relative to original insulation, flame retardant property, 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 elastoplastic body so that cable has certain elasticity, anti-extrusion.
5th, the inner sheath be woven into after pipe by alkali-free glass fibre band 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, heat preservation, anti-electricity, softness, it can be maintained in the case of subzero 54 degrees Celsius
Flexibility in 260 degrees Celsius of sustainable work, provides reliably protecting, anti-heat wave is resistant to≤1100 in short-term at 550 DEG C
The impact of DEG C high-temperature molten steel.
6th, outermost layer is equipped with cermet lining multiple tube so that cable has good wear-resisting, heat-resisting, anti-corrosion and anti-machine
The comprehensive performances such as tool impact and thermal shock.
7th, the improvement of this cable not only extends the service life of cable, but also with very strong tensile strength, has 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, which has a vast market demand.
