Control cable is from polyvinyl chloride insulation or the non-flame retardant type cable of polyethylene insulation, polyvinyl chloride or pe sheath, develop into the flame retardant type polyvinyl chloride insulation that begins the nineties in last century or flame retardant type polyethylene insulation, crosslinked polyetylene insulated or silicon rubber and fluoroplastic insulation (high-temperature field is share), flame retardant type pvc sheath or flame retardant type pe sheath, flame retardant type (mainly being divided into category-A, category-B, C class) silicon rubber and fluoroplastics cable, develop into the low-smoke halogen-free flame retardant control cable that begins the beginning of this century again, as seen the fire resistance to cable requires more and more higher.
Characteristic requirement to the cable low-smoke non-halogen flame-retardant is:
1, low smoke performance requires: minimum light transmittance 〉=60%;
2, Halogen performance requirement: pH value 〉=4.3, conductivity≤10 μ S/mm;
3, the bunchy fire resistance requires:
Category-A: comburant volume: 7L/m, for fire time: 40min, qualified index: the length of charing the most very much not should stop should not surpassing 1h for the flaming combustion time on the sample of fire back above the 2.5m that makes progress apart from the nozzle base on the sample;
Category-B: comburant volume: 3.5L/m, for fire time: 40min, qualified index: the length of charing the most very much not should stop should not surpassing 1h for the flaming combustion time on the sample of fire back above the 2.5m that makes progress apart from the nozzle base on the sample;
The C class: comburant volume: 1.5L/m, for fire time: 20min, qualified index: the length of charing the most very much not should stop should not surpassing 1h for the flaming combustion time on the sample of fire back above the 2.5m that makes progress apart from the nozzle base on the sample;
The low-smoke halogen-free polyolefin insulation is adopted in the insulation of low-smoke halogen-free inflaming-retarding cable at present substantially, and sheath adopts low-smoke and halogen-free flame retardant polyolefin jacket; The shield type control cable is also arranged, and above-mentioned all kinds of cable all can not reach the performance requirement that smokeless Halogen does not fire.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of smokeless Halogen fire-retardant type control cable, is the new generation product that substitutes the low-smoke halogen-free flame retardant control cable, and cost is suitable, and electric fireproof performance and environmental protection effect are better.
The utility model technical solution problem adopts following technical scheme:
Smokeless Halogen fire-retardant type control cable, comprise conductor, the extruded insulation layer is arranged on conductor, by the stranded cable conductor that forms of insulated wire cores, packing in the space in cable core between the core has total lapping layer outside cable core, be total screen outside described lapping layer, outside total screen is separator, and the outermost layer of cable is a stainless steel sheath.
Described conductor adopts and meets the 1st kind or the 2nd kind or the 5th kind of conductor structure stipulating among the GB/T3956.
Described insulating barrier adopts polyethylene or crosslinked polyethylene or cross-linking radiation polyolefin insulation material Halogen material to extrude and forms.
Described separator adopts high temperature resistance non halogen material band to form for wrapped two layers.
Described stainless steel sheath adopts the vertical bag welding of stainless steel band, and forms through the embossing processing.
Described total lapping layer is to adopt two layers of wrapped forming of polyester belt, and total lapping layer adopts the wrapped shielding of soft copper band or compound copper-plastics band or aluminium-plastic tape outward or adopts soft circular copper wire or total screen of zinc-plated circular copper wire braid shielded conduct.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
(1) outer jacket because of the utility model cable is that the vertical bag of stainless steel band is welded, stainless melting temperature is 1772 ℃, therefore, the utility model cable reaches under 750 ℃～1000 ℃ conditions in flame temperature, cable can not melt and burn yet, and insulation, filling and the lapping layer (band material) of cable the inside are isolated by outer jacket again, do not contact with air, cable itself can't form the condition of burning, so also can not produce dieseling because of aging, overload or short circuit.Eliminated the fire disaster that causes because of the cable spontaneous combustion, and the fire that cable causes causes direct or indirect economic loss in China is surprising, and the utility model cable has thoroughly solved the difficult problem of the fire safety of cable line, is the best fire-type control cable of cost performance.
(2) because the utility model cable has smokelessly, Halogen and the characteristic of not firing, the secondary disaster of cable under the fire condition also just thoroughly eliminated, and can not cause any negative effect to environmental protection, is environment-friendly type control cable worthy of the name.
(3) the utility model cable long service life.Because stainless steel outer jacket corrosion resistance is strong, the material and the air of cable the inside are isolated again, and the ageing process of insulation and other material delays greatly, and can reach 80～100 years the useful life of cable as calculated.
(4) because protective coverings of cable has adopted vertical bag welding embossing technology, still fire prevention, antiseptic property are good, water resistance might as well, can be used as submerged cable and use; Protection against rodents and termite-proof performance can be used as protection against rodents and termite-proof cable.
(5) because stainless steel sheath has adopted the embossing PROCESS FOR TREATMENT, and the bending radius and the common cable of cable are basic identical, installing does not need poling, stainless steel sheath to can be used as the armour use yet yet when laying, saved the plastic sheath material of armoring material and cable.
(6) particularly cable do not fire characteristic; or else the fire that the too high fire that causes of short circuit and fire hazard, ambient temperature that causes, artificial kindling material because cable material wears out are caused will can take place; can not discharge smog and halogen gas in the fire condition yet; therefore; the utility model is the revolutionary innovative technology of cable history the next item up concerning electric fireproof safety and environmental protection.
