Abstract

The utility model discloses a halogen-free flame-retardation fireproof control cable comprising conduction cores, fireproof mica layers, insulation layers, a wrapping tape and a sheath; the conduction cores are a plurality of strands in number; one strand of conduction core is wrapped by each insulation layer of a plurality of insulation layers; the fireproof mica layers are positioned between the conduction cores and the insulation layers; the conduction cores wrapped by the insulation layers are wrapped by one wrapping tape, and the wrapping tape is wrapped by the sheath; the conduction cores are tin-coated copper cores; the insulation layers are silicone rubber insulating layers; and the sheath is a polyolefin sheath. The halogen-free flame-retardation fireproof control cable has characteristics of halogen-free, low-smoke and flame retardation; flame retardation performance can reach A category requirements of IEC60332.3; so smog and poison gas emission can be reduced; and if burned in a flame environment at and below 800 DEG C, the cable can ensure more than 90 minutes of power charging to satisfy control requirements of emergency conditions.

Description

The halogen-free flameproof fireproof control cable
Technical field
The utility model relates to technical field of electric wires and cables, relates in particular to a kind of halogen-free flameproof fireproof control cable.
Background technology
Fire-resisting cable refers to still can keep within a certain period of time the cable of normal operation when fire burns.For important fire-fighting place circuits such as skyscraper, tunnel, subway, power station, intelligent buildings; for example control, monitoring, measurement and the route protection of emergency services such as fire alarm, fire-fighting equipment, emergency access transportation, illumination, fire-resisting cable is indispensable circuit transmission medium.The halogen-free flameproof fire-resisting cable can avoid causing secondary to endanger because therefore Halogen fire proofing not when fire takes place, can not produce a large amount of smog and poisonous corrosive hydrogen halides gas.But the flame-retardant performance of halogen-free flameproof refractory material and security performance are still waiting to improve.
Summary of the invention
The purpose of this utility model provides a kind of halogen-free flameproof fireproof control cable of excellent performance, has the characteristic of LSOH anti-flaming, and fire resistance can reach category-A requirement among the IEC60332.3, and can further reduce distributing of smog and pernicious gas; In 800 ℃ and following flame environment, burn, can guarantee to switch on more than 90 minutes, guarantee the control requirement of emergency.
Technical solution of the present utility model is:
The halogen-free flameproof fireproof control cable comprises and leads core, fire-resistant mica layer, insulating barrier, band, sheath; The described core of leading is multiply, described insulating barrier is that many and every insulating barrier are wrapped in one and lead core, described fire-resistant mica layer is led between core and the described insulating barrier described, and the core of leading of described many insulating barriers parcel is enclosed with a band around the periphery, and described band periphery is enclosed with sheath; The described core of leading is the tin-coated copper core, and described insulating barrier is silicone rubber insulation layer, and described sheath is polyolefin jacket.
As the further improved halogen-free flameproof fireproof control cable of the utility model, described fire-resistant mica layer is synthetic mica paper.Described synthetic mica molecular formula is KMg 3AlSi 3O 10F 2
As the further improved halogen-free flameproof fireproof control cable of the utility model, be filled with fire-retardant inorganic hydrogen aluminium oxide jelly between described insulating barrier and the described band.
As the further improved halogen-free flameproof fireproof control cable of the utility model, also be provided with sheath between described sheath and the described band, described sheath is the polyolefin sheath.
As the further improved halogen-free flameproof fireproof control cable of the utility model, also be provided with armour between described sheath and the described sheath, described armour is the steel-tape armouring layer.
Halogen-free flameproof fireproof control cable provided by the utility model possesses the characteristic of LSOH anti-flaming, cable stands outer burning things which may cause a fire disaster and fuses for a long time, the cable inside stuffing is separated out moisture with the step, stop cable to ignite, reach fire-retardant purpose, fire resistance can reach category-A requirement among the IEC60332.3, and can reduce distributing of smog and pernicious gas, is conducive to putting out a fire to save life and property of fire; In 800 ℃ and following flame environment, burn, can guarantee to switch on more than 90 minutes, guarantee the control requirement of emergency.
