Description
Technical field
The present invention relates to electric wire field, and in particular to a kind of crosslinked polyetylene insulated anti-interference control of high-environmental high fire-retardance
Cable processed.
Background technology
Phase is still suffered from when the plain edition low-smoke halogen-free inflaming-retarding cable fire-retardant rank that in the market largely circulates is not high and burns
When the disaster hidden-trouble, pollution sources and public hazards of degree are dangerous, in generation concrete on fire, flame can spread along cable and produce suitable
More smog and poisonous gas, secondary disaster is caused to modernization electrical equipment and has great corrosion, people can be caused to suffocate
Death, hinder the disaster relief.Electrical equipment in the market typically uses plain edition low-smoke halogen-free inflaming-retarding cable, and fire is occurring
During calamity, substantial amounts of dense smoke is often produced, and along with substantial amounts of toxic gas, easily cause the secondary disaster of equipment, to body
Body damages.If in the case of occurring unexpectedly, scene of fire can be because of caused a large amount of smog in electric wire combustion process
And between missing effective rescue, and victim as electric wire in combustion caused toxic gas and suffer from can not
The disease or death by suffocation of healing.
The content of the invention
In order to overcome the deficiencies in the prior art, there is provided a kind of with excellent soft just shifting property, high fire-retardance, corrosion resistant
Erosion, nontoxic low cigarette, jamproof crosslinked polyetylene insulated high-environmental high fire-retardance anti-interference control cable.
To achieve the above object, the present invention, which provides, hands over a kind of crosslinked polyetylene insulated high-environmental high fire-retardance antidisturbance control electricity
Cable, including cable core, described cable core are formed by an insulated wire cores and a control conductor pair twist arranged side by side；In the space of cable core
Place's filling netted gasket for packings of high fire-retardance pp, high fire-retardance band glue heat-shrink tube is externally provided with cable core, is compiled outside high fire-retardance band glue heat-shrink tube
Steel wire screen layer is knitted, silicon rubber separation sleeve is externally provided with steel wire screen layer, copper strip shielding layer is externally provided with silicon rubber separation sleeve,
Wrapped double-layer and double-side synthetic mica tape outside copper strip shielding layer, extrudes polyvinyl chloride oversheath outside two-sided synthetic mica tape, and
Polyvinyl chloride oversheath outer surface scribbles one layer of fire clay.
Preferably, described insulated wire cores include aluminium alloy conductor, are extruded outside aluminium alloy conductor crosslinked polyetylene insulated
Layer, the wrapped environmentally friendly high fire-retardance alkali-free glass cloth braid over braid outside crosslinked polyetylene insulated layer, in environmentally friendly high fire-retardance alkali-free glass cloth
Copper strip shielding layer is woven outside braid over braid.
Preferably, described control conductor includes tinned copper conductor, is extruded outside tinned copper conductor crosslinked polyetylene insulated
Layer, the wrapped self-locking nylon cable tie outside crosslinked polyetylene insulated layer.
Compared with prior art, the beneficial effects of the present invention are：
1st, filling uses the netted gasket for packings of high fire-retardance pp, light specific gravity, and smoke density is low so that cable has a high temperature resistant, flame resistant, no
Smoke and it is not halogen the features such as.
2nd, high fire-retardance band glue heat-shrink tube is externally provided with cable core, outer layer uses high-quality, soft crosslinked polyolefin materials, internal layer
PUR Compound Machining forms, and has the advantages that insulating corrosion, wear-resisting, low melting point, waterproof, sealing and high adhesiveness so that electricity
Cable improves mechanical protection intensity while flexibility is kept.
3rd, using two-sided synthetic mica tape so that the high and low density of cable strength, high-temperature insulation are good, good heat-insulation effect.
4th, provided with double-level-metal screen layer, strengthen effect of the limitation electric field in insulating barrier, make direction of an electric field and insulation half
Footpath direction is consistent（I.e. radially）, metallic shield is with ground, and electric field is terminated on metal tape, and metal tape is outer there is no electric field, significantly
Improve the interference free performance of cable.
5th, oversheath outer surface scribbles one layer of fire clay so that the refractoriness of cable reaches 1580 degrees Celsius, in high temperature
Under the conditions of can keep the stability of volume, and with resistance to slag, the repellence to rapid heat cycle, and certain mechanical strength.
6th, the multiple fire proof construction such as prevented fires from outside to inside present invention employs core fire prevention, cable core fire prevention, cable so that electricity
Cable fire safe type is the hundred times of other common cables, provides anti-flammability, the fire resistance of cable significantly so that cable is in a fire
Service life greatly improves, and the time used also greatly improves.
7th, the present invention is to using structure made of environment-friendly materials, will greatly reduce caused toxic gas during disaster occurs
With dense smoke, high-environmental anti-flammability is realized, a large amount of smog and HCL poisonous gas will not be produced, secondary pollution, product will not more occur
The convenience that intensive degree height, raising equipment and Personal Safety and cable use, makes our product more have market
Competitiveness.With the increase of City Building and the density of population, the product has the wide market demand.
