technical field:
The utility model relates to cable, relates in particular to a kind of flame retardant type aluminium alloy cable.
background technology:
Along with the development of advancing by leaps and bounds of power industry, the demand of cable just increases progressively with 15% annual growth.Wires and cables industry conductor used is mainly copper and aluminium now, and because copper valency is soaring at a high speed, the cable cost of copper core conductor is high, thereby proposes with aluminium for copper one after another all over the world.The explored aluminium reserves of China rank first in the world, there is abundant raw material deposit, and copper resource is relatively deficient, need greatly at present import, in order to change the dependence of cable to copper material, make full use of Domestic Resources, guarantee that the key of power industry sustainable development is to widely popularize aluminium as the conductor of electric wire.In cable industry, aluminium is the ideal material that replaces copper, but fine aluminium conductor exists again some shortcomings as: bad mechanical strength, easily creep, easily overload heating etc.
At present, the structure of conventional aluminium conductor cable is the stranded compact conductor of aluminium monofilament, insulating barrier, steel-tape armouring layer, outer jacket.The coefficient that presses of conventional stranded conductor reaches 0.9 left and right, reach same electric property, the sectional area of aluminium conductor need to or increase 50% than large two grades of copper conductor, and conductor diameter is larger, steel-tape armouring level of security is low, when being subject to extraneous destructive power, its defensive ability/resistance ability is poor, easily causes puncturing, and Heavy Weight, installation cost is quite high, poor corrosion resistance in addition, and useful life is not long.This common cable structure, cannot in adverse circumstances, move for a long time, and processing is more complicated and difficult.Under normal circumstances, existing cable can meet the demands, if but cable be used in adverse circumstances and cable security required, in higher environment, can not to meet instructions for use.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of flame retardant type aluminium alloy cable, and cable has that volume is little, lightweight, fire resistance is superior, good flame retardation effect, the tension of conductor, creep, percentage elongation, conductance etc. are good, and have compressive property, long service life.
The technical solution of the utility model is as follows:
Flame retardant type aluminium alloy cable, it is characterized in that: comprise at least one core, single core consists of the coated coextrusion insulated layer of boron aluminium alloy conductor and outside thereof, the mutual stranded bunchy of core or single core form cable core, outside core and between cable core, be provided with the packed layer that the free of contamination dustless mineral wool rope of high flame retardant forms, described cable core, the periphery of packed layer is enclosed with high flame resistance, low smoke halogen-free flameproof band lapping layer successively, high-fire-resistance oxygen barrier layer material extrudes formation inner covering, the metal armouring layer that aluminum alloy strip lock armo forms, high-fire-resistance protective cover material extrudes the external sheath layer of formation.
Described flame retardant type aluminium alloy cable, is characterized in that: described core quantity is 1 ~ 5.
Described flame retardant type aluminium alloy cable, is characterized in that: described coextrusion insulated layer adopts irradiation type cross-linked type polyethylene and low-smoke halogen-free polyolefin Insulation Material double-layer coextrusion to form.
The beneficial effects of the utility model are as follows:
(1) the utility model compact conformation, reasonable, and the technological process of manufacturing is simple, its cost is low, volume is little, lightweight, fire resistance is superior, and the tension of conductor, creep, percentage elongation, conductance etc. are good, and it is high to have compressive property, long service life.
(2) conductor described in the utility model is boron aluminum alloy materials, in boron aluminium alloy, increased copper, iron, the elements such as magnesium, the conductance of conductor is 62.1% of copper, density only has 29.8% of copper conductor, even if the sectional area of aluminium alloy conductor is brought up to 150% of copper conductor sectional area, the weight of aluminium alloy conductor also only has 45% of copper conductor, this makes the tensile strength of aluminium alloy conductor also have certain advantage with respect to copper conductor, thereby the yield strength of aluminium alloy conductor makes the croop property of aluminium alloy conductor approach the croop property of copper conductor close to copper conductor, on elongation at break, aluminium alloy conductor and copper conductor are basic identical.Creep resistance has improved 300% with compression property, and its tensile strength is approximately 150% of fine aluminium, and yield strength is about 210% of fine aluminium.
(3) the insulation irradiation type cross-linked type polyethylene of the utility model cable and low-smoke halogen-free polyolefin Insulation Material double-layer coextrusion form, wherein crosslinked polyethylene has good electrical property and mechanical performance, and halogen-free low-smoke flame retardant material has extraordinary fire resistance, thereby the existing good electrical property of the insulation that makes cable and mechanical performance, also have very outstanding fire resistance.
(4) filling of cable described in the utility model adopts the dustless mineral wool rope of high flame retardant pollution-free, and dustless mineral wool rope temperature resistant grade can reach 800 ℃, has fine fire resistance and fire resistance, and to environment environmental pollution.
(5) inner covering of the utility model cable employing high-fire-resistance oxygen barrier layer material extrudes and forms, and this material has oxygen index high (40), and fire resistance is good, and has Halogen, nontoxic, free of contamination feature.
