Description
Technical field
The utility model relates to a kind of structure of cable, and specifically a kind of structure of flexible mineral protective layer fireproof cable, belongs to field of cable technology.
Background technology
Cable Firing Accident mainly contains two kinds of reasons, and the fault of cable own causes fire and extraneous burning things which may cause a fire disaster to cause fire.A large amount of dense smoke and toxic gas can be produced after ignition of cable, not only serious environment pollution but also harmful, and cable fire easily makes fault spread, burns out the capital equipment such as power distribution cabinet, transformer, affect power grid security to power, bring massive losses to people's production property safety.
The occasion that domestic comparatively safe class requirement is higher many employings GB/T 18380 category-A is fire-retardant judges the fire-retardant of cable and refractory ability with BS6387 standard C .W.Z test, its most typical product is the BTTZ type magnesium oxide mineral insulation cable meeting GB/T 13033, a lot of enterprise is also all at flexibility of research and development fireproof cable in recent years, but most product is to pass through for the purpose of test, product when Design and manufacture, can not take into account cable electric property and useful life isoelectric line cable key parameter.Decompose under also creating the easy moisture absorption of insulation, high temperature simultaneously and produce other hidden danger such as fuel gas, useful life is short, so exploitation and the flexible fire-proof cable that designs a kind of excellent combination property are the task of top priority.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art; there is provided that a kind of high electrical performance, flexibility are good, mounting and installation is simple, stable performance, fire-retardant, catch fire after anti-fire capability strong, the flexible mineral protective layer fireproof cable of long period safe power supply can be kept.
The purpose of this utility model is achieved through the following technical solutions: a kind of flexible mineral protective layer fireproof cable; comprise cable core and oversheath; described cable core by insulated wire, filler is stranded forms; described insulated wire by conductor, be placed in the outer field insulating barrier of conductor and form; it is characterized in that; described insulating barrier is double-layer insulating structure; be made up of the flexible mineral flame retardant coating of internal layer, outer field crosslinked polyetylene insulated layer; be provided with the fireproof jointing sheath that Ceramic silicon rubber material is made outside described cable core, described oversheath is placed in outside fireproof jointing sheath.
Described oversheath is made up of halogen-free and low-smoke flame-retardant polyolefin sheathed material.
Described conductor is annealed by multicore, and circular copper wire is stranded to be formed, and the precision for the circular copper wire monofilament of stranded conductor is 0.003mm, and conductor diameter tolerance is 0.01mm.
In order to the convenience used and install, the utility model all adopts the regular lay configuration of multicore annealing circular copper wire in conductor design, and in order to ensure that cable has good electric property, conductor adopts the wire drawing and annealing of German Ni Huofu and wringing equipment to carry out retrofit, precision wherein for the round copper monofilament of stranded conductor is 0.003mm, and conductor diameter tolerance is 0.01mm.There is not the phenomenons such as single line drawing-down (passing through measuring resistance), broken string, oxidation in wire drawing and annealing process.In copper monofilament stranding process, pitch is even, cable conductor outward appearance rounding, the strict guarantee quality of conductor.In Design and manufacture process, twisted pair wire pitch reasonably controls, and while ensureing product good electrical properties, with certain flexibility, ensures that cable sustainablely bends, be convenient to small space and installs, convenient and swift.
Insulating barrier adopts the flame retardant coating made of flexible mineral and cross-linking polyethylene materials double hyer insulation, cable is provided with electric property that good fire resistance in turn ensure that cable excellence.
Extrude high crust, eutectics macromolecule composite ceramic coating silastic material as fireproofing of cable protective layer with squash type expressing technique cable core is outer, its by built-in electrical insulation core and the external world completely isolated, insulate with composite double layer fire insulation type and form dual fail-safe of preventing fires.Cable is when by flame ablation, and Ceramic silicon rubber can be ablated within the extremely short time, after add very soon in the course of reaction of ceramic, change into hard ceramic-like material, form the isolation layer that one deck is good, stop burning away of flame, play good flameproof effect.Ensure that cable is steady in a long-term under thermal-flame to run, water resistant spray performance under resistance to mechanical impact, thermal-flame under thermal-flame.
Oversheath adopts the halogen-free and low-smoke flame-retardant polyolefin sheathed material of high-quality, ensures cable low-smoke non-halogen flame-retardant performance.Because inorganic anti-flaming material (filler) is filled in a large number, the machinery of halogen-free and low-smoke flame-retardant polyolefin sheathed material and processing characteristics are declined to a great extent, to extrusion temperature scope and Spreading requirements higher.We conducted a large amount of engineer testings, determine rational extrusion temperature, and for the smaller situation of material extending, mould is adjusted, achieves the balance of speed of production, presentation quality, mechanical performance and LSOH anti-flaming performance.
The utility model adopts flexible mineral flame retardant coating and crosslinked polyetylene insulated double-layer insulating structure, compares the electrical property that single mica tape insulation ensure that cable excellence, can not be subject to again the impact of wet environment.And excellent electrical property and useful life can be ensured compared to Ceramic silicon rubber insulation.
The utility model adopts Ceramic silicon rubber fireproof jointing sheath, and relative aluminium hydroxide protective layer is more soft, and performance is also more stable.And relative aluminium sheath protective layer, even if be subject to the calcination of higher flame temperature, cable can keep work too.
The utility model can select polytype conductor, meets the different needs installing occasion.
The utility model is easy for installation, can contain the demand of pressure common power cable all size.By the reasonable selection of combination rational in infrastructure and cable material, product not only has good fire protecting performance and softness, possesses the performances such as excellent electric property and low-smoke non-halogen flame-retardant category-A simultaneously, reduces mounting and installation cost, improves security of system.
The utility model meets BS6387 regulation C, W, the requirement of Z-type fire resistance test completely, has site operation mounting process simple, cable length long and whole continuously, there is excellent electric property and mechanical performance simultaneously.The distribution of the complete performance requirement of holding circuit, illumination, control and warning system is needed under being applied to Fire Conditions.
