Description
Technical field
The present invention relates to a kind of cable, be specifically related to a kind of low-smoke halogen-free cable.
Background technology
Along with the fast development of national economy, as the electric wire of national economy aorta, its
Consumption and range are increasing.In recent years, power plant, transformer station, smelting and oil
The industries such as chemical industry, very big to the demand of cable.
Power cable is widely used in respectively as a kind of carrier carrying electric energy and distribution electric energy
Individual industry, draws due to artificial improper use or the impact of making the thunderbolt extraneous factor such as earthquake
The cable risen on fire happens occasionally, according to incompletely statistics, and the fire thing that China in 1996 occurs
In therefore, because just accounting for 1/3rd caused by cable and wire, near in fire fatality personnel
66% is because the toxic smog that produces when sucking electric wire burning and death by suffocation, tradition
Cable typically uses the such as polrvinyl chloride of the material containing halogen, second third to reach fire-retardant effect
Rubber etc., can absorb oxygen in a large number and can make the excellent of fire extinguishing rapidly when halogen containing material has burning
Point, but shortcoming is ignition energy gives out high concentration chlorine smog, low visibility make escape personnel without
Method escape recognition route, secondly chlorine has the strongest toxicity, by connecing with the water vapour in air
Touch and can also generate the harmful gass such as there is corrosive hydrogen halides, carbon monoxide, carbon dioxide.

Beneficial effect: compared with prior art, its remarkable advantage is the present invention: the present invention is overall
Structure arranges rationally, uses by being located at the aramid fiber bundle at middle part and being wrapped in outside aramid fiber bundle
The oxygen-free copper wire harness composition conductor in portion, allows aramid fiber bundle to carry some power, it is possible to reduce to lead
The stress of body copper wire, improves tension and the bending resistance of conductor, and oxygen-free copper wire harness, than
Fine copper, fine aluminium cable are more stable, and electrical conductivity is higher, use inorganic chopped fiber adhesive-layer as resistance to
Fire bed, can play and well isolate flame retardant effect, even and if catch fire, also can alleviate greatly
Naturally pollute, use crosslinked polyetylene insulated layer, good insulation effect can be played, adopt
With aramid fiber silk braid, improve the intensity of conductive unit part further, use three layers of nothing
Halogen belting layer, is effectively improved overall flame effect, uses low-smoke halogen-free polyolefin restrictive coating, can
To play Global Macros effect, avoid when catching fire simultaneously, produce a large amount of toxic and harmful,
Described conductive unit diameter accounts for the 1/3 of cable body diameter, then by each layer with the use of,
Conductive unit runs the most reliable, and using effect is the most preferable, and whole service life is long, meets
Actual operation requirements.
