Description
Technical field:
The utility model relates to cable, specifically a kind of aluminium alloy conductor stainless steel sheath halogen-free environment-friendly type power cable.
Background technology:
Used cable is low-smoke halogen-free inflaming-retarding cable substantially in China public place at present, conductor has copper core and aluminium core, and the copper resource is in China's shortage, price is also very high, reached more than 70,000 yuan one ton, and China's bauxite resource is abundant, but the creep resistant and the extension property of common electrician's aluminium are poor, cause the safety in operation in the cable running poor, so it is less at the power cable that China makes conductor wire core with aluminium, along with the aluminium alloy of 8000 series is produced in batches in China, adopt 8000 series alloys to become a kind of possibility as conductor, supply line in north america such as the U.S. 90% has adopted 8000 series alloys to make the conductor of power cable, thus adopt the aluminium alloy of 8000 series to make conductor, China required in a large amount of utilizations.
And for low cigarette, Halogen and fire-retardant performance, now the low-smoke halogen-free inflaming-retarding cable of usefulness will reach smokelessly, the performance requirement of Halogen and difficult combustion really is difficult to, and is very big to the material cost increase, and the employing metal is made sheath and just is easy to.Though materials such as insulation can fuel, has been completely cut off air by metallic sheath, can't burn or discharge smog and pernicious gas.
Summary of the invention:
For overcoming the defective of prior art; the purpose of this utility model is to provide a kind of aluminium alloy conductor stainless steel sheath halogen-free environment-friendly type power cable; it is the new generation product of instead of copper, aluminium core low-smoke halogen-free flame retardant power cable; save the copper resource; the cost performance height, electric fireproof safety and environmental protection effect are better.
The utility model technical solution problem adopts following technical scheme:
Aluminium alloy conductor stainless steel sheath halogen-free environment-friendly type power cable, by conductor and be extruded in the outer field insulating barrier of described conductor and constitute insulated wire cores, described conductor is an aluminium alloy conductor, the edge cores that thoroughly do away with are twisted into cable conductor more, the cable core gap is provided with packed layer, outside described cable core and described packed layer, be surrounded with separator, the vertical embossing type stainless steel oversheath that is surrounded by outside described separator.
Design feature of the present utility model also is: described insulating barrier is crosslinked polyethylene or cross-linking radiation polyolefin insulation material.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
(1) conductor because of the utility model cable has adopted 8000 serial electrician's level aluminium alloys to make conductor wire core, conductor ampacity is suitable with the aluminium core, it is 61% of copper conductor, and the aluminium alloy conductor material cost is about about 20% of a copper conductor material cost, and 8000 serial electrician's level aluminium alloy make conductor, the creep-resistant property and the extension property of conductor are good, have improved the using system reliability of operation greatly.
(2) outer jacket because of the utility model cable has adopted vertical bag welding embossing type stainless steel oversheath, stainless melting temperature is 1772 ℃, therefore, protective coverings of cable reaches under 750 ℃～1000 ℃ conditions in flame temperature, cable can not melt and burn yet, and insulation, filling and isolation and the lapping layer 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.
(3) because the utility model cable has smokelessly, Halogen and difficult characteristic of firing, the secondary disaster of cable under the fire condition also significantly reduced, and can not cause negative effect to environmental protection, is environment-friendly cable worthy of the name.
(4) the utility model cable long service life.Because stainless steel oversheath corrosion resistance is strong, the material and the air of cable the inside are isolated, and the ageing process of insulation and other material delays greatly, and can reach 80 years the useful life of cable as calculated.
(5) because cable jacket has adopted stainless steel sheath, still do not have fire protecting performance, its antiseptic property, water resistance, can be used as submerged cable and use.
(6) because the stainless steel oversheath has been carried out the embossing PROCESS FOR TREATMENT, the bending radius of the utility model cable can be compared with common cable, and installing does not need poling when laying yet, and has saved the poling material.
(7) the stainless steel oversheath also can be used as the screen use, has good magnetic field shielding effect, also alternative existing steel-tape armouring or lock armo cable.
(8) owing to adopted aluminium alloy conductor and stainless steel oversheath, saved the copper resource, cable is in light weight, need not poling, and is easy for installation, and the construction investment cost reduces, and cost performance is far above existing power cable.
The technical performance index of the utility model cable:
2.1 rated voltage: 0.6/1kV or 1.8/3kV.
2.2 the highest for a long time permission working temperature of cable: 90 ℃, 105 ℃ and 125 ℃, the short time allows to reach: 250 ℃.
2.3 minimum bending radius: be not less than 10 times of the outside diameter of cable.
2.4 conductor resistance meets the regulation of aluminium conductor in 3956 in the time of 20 ℃.
2.5 manufacture test voltage: 3500V/5min or 6500V/5min.
2.6 insulation resistance: in the time of 20 ℃, be not less than 1000M Ω/km.
2.7 there is not smoke performance: light transmittance 〉=90% (low smoke performance be 〉=60%)
2.8 Halogen performance: pH value 〉=4.3, conductivity≤10 μ S/mm.
2.9 fuel performance: cable is under 750 ℃～1000 ℃ flame temperature, and for fiery 40min, cable jacket can not melt and burn yet, cable inside is only burnt near burning things which may cause a fire disaster, the distance of burning stops also not have flame on the cable and prolonging combustion for behind the fire less than common low-smoke halogen-free inflaming-retarding cable.
2.10 shielding properties: shielding rejection coefficient≤0.3%.
