Preferably, the 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 utility model are：
1st, filling is using the netted gasket for packings of high fire-retardance pp, light specific gravity, and smoke density is low so that cable has high temperature resistant, fire resisting
Flame, not smoke and it is not halogen the features such as.
2nd, high fire-retardance band glue heat-shrink tube is externally provided in cable core, outer layer uses high-quality, soft crosslinked polyolefin materials, internal layer
Hot melt adhesive Compound Machining forms, and has many advantages, such as 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, equipped with double-level-metal shielded layer, strengthen effect of the limitation electric field in insulating layer, make direction of an electric field and insulation half
Diameter 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 is coated with 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.
The multiple fire proof constructions such as the 6th, the utility model employs core fire prevention, cable core is prevented fires, cable is prevented fires from outside to inside, make
The hundred times that cable fire type is other common cables are obtained, provide anti-flammability, the fire resistance of cable significantly so that cable is in fire
Service life greatly improves in calamity, and the time used also greatly improves.
7th, the utility model is to using structure made of environment-friendly materials, will greatly reduce generated toxic during disaster occurs
Gas and dense smoke, realization high-environmental anti-flammability, will not generate a large amount of smog and HCL poisonous gas, secondary pollution will not more occur,
The convenience that product intensive degree height, raising equipment and Personal Safety and cable use, makes our product more have
The market competitiveness.With the increase of City Building and the density of population, which has a vast market demand.
