A kind of environment-protecting asepsis fireproof cable

Technical field

The utility model relates to a kind of cable, specifically a kind of environment-protecting asepsis fireproof cable.

Background technology

According to data, in the fire that China occurs, because the fire electrically caused accounts for the half of total fire number, because cable is aging or overload uses the fire caused to account for larger proportion in electrical fire, simultaneously because the toxic gas sent during fire shot-firing cable can cause mass casualties, and hinder fire fighter to put out a fire, it is very important for therefore correctly designing fire-resisting cable.

The existing construction of cable comprises many conductors, be coated on insulating barrier, braid and restrictive coating four parts outside each conductor, wherein, conductor and insulating barrier form insulated wire cores, and braid is wrapped in the outside of many insulated wire cores, and restrictive coating is coated on the outer surface of braid.

But in signals transmission, the fire resistance of the cable of this structure is poor, easily produces toxic gas, when running into high temperature environmental activity on fire, huge potential safety hazard can be caused.

Utility model content

In order to make up the deficiencies in the prior art, it is better that the utility model provides a kind of fire resistance, and can not produce a kind of environment-protecting asepsis fireproof cable of toxic gas time on fire.

The utility model solves the technical scheme that its technical problem adopts: a kind of environment-protecting asepsis fireproof cable, comprise insulation core wire, asbestos cord, mica tape, drain wire, aluminium foil strip and sheath, described every root insulation core wire is made up of conductor, the insulating barrier be wrapped in outside conductor, braid and ceramic polyolefin layer, and there are an insulation core wire or two insulation core wires in this described cable inside.

Further, described insulating barrier is Ceramic silicon rubber layer, and silicon rubber is mecystasis before sulfuration, after sulfuration, owing to adding vulcanizing agent, at a certain temperature, rubber molecule is cross-linked into network molecular structure, so ceramic silicon rubber forms elastomer after curing, good insulation preformance, when meeting fire burning, combustible combustion release LSZH gas, after combustible combustion, residue filler is at high temperature condensed into porcelain lump.

Further, described insulating barrier periphery is wound with braid.

Further, described braid is glass braid, the count of glass fiber is more than 70%, glass fiber is high temperature resistant, in a fire, glass fiber is nonflammable, and internal layer silicon class carbide firmly can be fixed on around conductor, make the shock resistance of insulation core wire energy and vibration, and when making fire, circuit still normally can work.

Further, outside described braid, be extruded with one deck ceramic polyolefin layer, the low cigarette of ceramic polyolefin combustible, Halogen, nontoxic, under high temperature action, not only self can form ceramic lump, and internal layer forms inorfil, plays good fire insulation heat-blocking action.

Further, be surrounded with one deck mica tape outside described insulation core wire, the overlap joint density of mica tape is more than 50%, and mica tape is nonflammable, can keep off cigarette, and flame enters cable internal layer, and mica tape can make the retarded combustion in a fire of cable internal layer.

Further, one deck aluminium foil strip is surrounded with outside described mica tape.

Further, one deck sheath is extruded with outside described aluminium foil strip.

Further, described sheath is low smoke and zero halogen sheath.

Further; when there are two insulation core wires this cable inside; asbestos cord is filled with between described insulation core wire and mica tape; asbestos cord is incombustible; the effect of protection insulation core wire can be played in fire; and a drain wire is installed between mica tape and aluminium foil strip, the diameter of described drain wire is less than the diameter of section of the conductor of insulation core wire.

The cable that the utility model provides; glass fiber is woven with and the protection layer by layer having the nontoxic low-smoke fireproof materials such as ceramic polyolefin, mica tape owing to having outside the conductor in cable; and be also filled with non-flammable asbestos cord between insulation core wire and mica tape during two insulation core wires; so this cable can play fireproof effect; ensure the supply of electric power signal; even and if catch fire, its combustible also can not produce toxic gas, thus environment friendly and pollution-free.
