The utility model discloses can reach the fire resistance rating requirement of BS6387 regulation, also have site operation installation simple process, the compliance is high, and the long and whole root of cable length has excellent electric property and mechanical properties in succession simultaneously, and the wide application need keep distribution, illumination, control and alarm system that the cable integrality can require under the conflagration condition.
Description
Technical field
The utility model relates to a kind of structure of fireproof cable, and the structure of the super flexible fire-proof cable of especially a kind of mica insulation chain Sheathed metal cover protection, belongs to field of cable technology.
Background technology
The matured product meeting BS6387 standard C .W.Z experiment and GB/T18380A class flame-retardancy requirements is in the market the BTT class cable product of copper core copper sheath magnesium oxide insulated, although the minimum bending radius of this cable is very little is the 2-6 times of outside diameter of cable, but such cable is harder, lay very difficult at the construction field (site), special more in Turning regions place, constructional difficulties is obvious.
Thus need to research and develop that a kind of field installation process is simple, cable length long, be convenient to be arranged on the high and flexible fire-proof cable having metallic sheath to protect of the flexibility in more place of turning.Although someone proposes the imagination of multiple material and structure for this reason, the utility model has the features such as material is special, structure simple, advanced technology.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, develops that a kind of field installation process is simple, cable length is long, is convenient to that more place is installed in bending place flexibility is high and super flexible fire-proof cable protected by mica insulation that is that have metallic sheath protect chain Sheathed metal cover.
The purpose of this utility model is achieved through the following technical solutions: the super flexible fire-proof cable of mica insulation chain Sheathed metal cover protection, comprise cable core and oversheath, described cable core forms by some cores are stranded, it is characterized in that, described core is made up of twisted copper conductors, the mica insulation layer be placed in outside twisted copper conductors, the outer wrapped inorganic mineral fire insulation insulating barrier of mica insulation layer; Heat insulation safeguard function layer is extruded with outside described cable core; the outer wrapped high tenacity oxygen barrier type high flame-proofing protective layer of heat insulation safeguard function layer; be provided with chain Sheathed metal sheath protective layer outside high tenacity oxygen barrier type high flame-proofing protective layer, oversheath is coated on outside chain Sheathed metal sheath protective layer.
Described mica insulation layer is made up of high temperature resistant three-in-one fluorophologopite.
Described inorganic mineral fire insulation insulating barrier is formed outside mica insulation layer by high type insulating wrapping strip is wrapped.
Described high type insulating wrapping strip is made up of refractory ceramic fluidized polymer, inorganic mineral glue.
Described heat insulation safeguard function layer is made up of aluminium hydroxide, refractory ceramic fluidized polymer, inorganic mineral glue.
Described high tenacity oxygen barrier type high flame-proofing protective layer is made up of the oxygen barrier high flame retardant band adding metal hydrate.
Described chain Sheathed metal sheath protective layer is made up of the non-magnetic stainless steel material or other nonmagnetic materials adopting chain armoured process.
Described oversheath is extruded in outside chain Sheathed metal sheath protective layer by low smoke, zero halogen macromolecular material and forms.
In the utility model, the high type insulating wrapping strip that inorganic mineral fire insulation insulating barrier is made up of refractory ceramic fluidized polymer, inorganic mineral glue etc., it has fire insulation performance and has good insulation property; There is heat insulation safeguard function layer to be made up of aluminium hydroxide, refractory ceramic fluidized polymer, inorganic mineral glue, adopt and extrude technique, there is fire resistance and stop external high temperature to enter cable inside, there is fabulous softness, material cracks when preventing bending; High tenacity oxygen barrier type high flame-proofing protective layer at high temperature forms metallic compound carbonizing meshy structure and the crystallization water; Chain Sheathed metal sheath protective layer has can bear mechanical external force and super ductile metal sheath performance; Low smoke, zero halogen macromolecular material sheath to cable available protecting, and has the features such as fire-retardant, low cigarette, Halogen.
Innovative point of the present utility model:
1, chain Sheathed metal sheath is adopted, can continuous seepage, therefore cable length is grown and the whole mechanical performance not only cable being provided to excellence continuously and because its structure is special, the metallic sheath of other versions has unrivaled ultra-flexible energy on year-on-year basis, and is more conducive to distributing of heat;
2, heat insulation safeguard function layer is had to have excellent heat insulation safeguard function, at high temperature heat-barrier material forms heat-barrier coating and decomposes water outlet, effective prevention external high temperature enters cable inside, strengthen inside cable structure high-temperature resistance, and due to the advance of material, there is material cracks when fabulous softness prevents bending, form double-deck super flexible cable structure with chain Sheathed metal sheath;
3, high tenacity oxygen barrier type high flame-proofing protective layer at high temperature forms metallic compound carbonizing meshy structure and the crystallization water; there is good smoking heat absorption capacity starvation; the crystallization water that surface is separated out reduces heat invasion, forms double-deck flameproof protection with there being heat insulation safeguard function layer.
The utility model can reach the fire resistance rating requirement that BS6387 specifies, also have site operation mounting process simple, flexibility is high, cable length long and whole continuously, there is excellent electric property and mechanical performance simultaneously.The utility model needs maintenance cable integrity to require distribution under being widely used in Fire Conditions, illumination, control and warning system.
