Description
Technical field
The present invention relates to technical field of alloy, particularly relate to environment-friendly type aluminium alloy conductor and preparation method thereof and comprise the power cable of this aluminium alloy conductor.
Background technology
For a long time, people to the selection of low-voltage cable for building, normally based on copper.Think copper conductor all higher than other conductors in electric property and degree of reliability, be the only selection being used as cable material, copper core cable has the features such as resistivity is low, intensity is high, current capacity is large.Along with the development of China's urbanization, urban power distribution network is as the Infrastructure of urban construction, the demand of power cable is increasing, copper core cable application quantity increases sharply, Copper Product in China material usage quantity has accounted for more than 90% of line cable industry, and power cable proportion in the cost of power grid construction significantly improves.But copper is as tellurian a kind of scarce resource, especially in our country, ore reserve are very limited, a large amount of dependence on import of Copper Ores, and price is constantly climbed to a higher point, and cable cost more and more causes the concern of investor; Meanwhile, copper cable difficulty in construction and installation is large, easily steals, the easy shortcoming such as aging; Pre-treatment and the refining of adding domestic discarded copper lack perfect " three wastes " process and supervision, and seriously polluted, China's environment has paid heavy cost.Therefore, people expect have more suitably cable to replace copper core cable.
Facts have proved, copper and aluminium are the most suitable materials of loaded current, are the main selections of electric wire in the world at present.China's bauxite resource, electrolytic aluminum production capacity surplus, aluminium becomes the first-selected alternative metals of electric wire, replaces copper to receive the concern of investigator with aluminium.
At present, domestic aluminium is for copper mode having aluminium, copper cover aluminum, aluminium alloy three kinds.
Aluminium has bad mechanical strength, easily fractures; Perishable, need frequent fastening screw; , there is potential safety hazard in easy overload heating; Surface very easily forms oxide film and increases the shortcomings such as contact resistance, limits the application of aluminum core cable and line.
Copper cover aluminum cable is the coated layers of copper in uniformly continous ground on aluminum core line, makes the copper on contact surface, aluminium atom form metallurgical binding, forms a kind of bimetal stratified composite.Copper cover aluminum cable has given full play to good electric conductivity and the lightweight feature of aluminium of copper, but tensile strength is still poor, and manufacture process requirement is higher, and waste and old cable recycling difficulty is large.
Aluminium alloy cable is in aluminium conductor, add relevant trace element, and comparatively fine aluminium conductor is low to make its resistivity, and it is bending, resistance to compression creep and physics, the mechanicalness such as corrosion-resistant effectively improve.Compare copper cable, aluminium alloy cable then possesses the unrivaled superiority of copper cable in weight, price and project installation etc.Under the prerequisite of identical electric property and better mechanical property, aluminium alloy cable has more the advantage such as economy and environmental protection, and Application Areas is extensive, is a kind of copper core cable substitute preferably.Therefore, aluminium alloy becomes the focus of research as cable conductor.
In the aluminium alloy trade mark of international aluminium employer's organization, the aluminium alloy as conductor mainly contains AA6000 and AA8000 series conductor.AA6000Al-Mg-Si (Aludur) serial conductor is mainly used in high voltage overhead lines and aluminium bus array, and this two classes conductor is all exist with hard state conductor, and the connection of joint is to be welded as master.AA8000A1-Mg-Cu_Fe (magnalium copper-iron alloy) series is the soft trick alloy be really used on distribution line.Aluminum-alloy conductor material of the prior art is comparatively excellent in corrosion resistance nature and mechanical property etc., but also has following shortcoming:
1. anti-fatigue performance is poor: in temperature, under the effect of external force and deadweight, As time goes on, by producing the creep of irrecoverable tension set slowly, very harmful to cable, point of contact is caused not press tightly, pressure reduces contact resistance is increased rapidly, after electric current flows through, causes joint overheated, or sparking, and then cause potential safety hazard.The tensile strength of copper material, aluminium alloy is 200 to 400,91 to 23 respectively.The tensile strength of existing aluminium alloy conductor only has the half of copper conductor.Toughness is not good enough, and the number of torsions that can bear is insufficient, as long as the torsion of several times certain angle when mounted, conductor will crack, and breach will generate heat, corrode, presence of fire.These anti-fatigue performances all determining existing aluminium alloy conductor are poor, easily occur quality problems, affect the work-ing life of aluminum alloy materials or bring potential safety hazard.
2. poorly conductive, because resistivity is high, the current capacity that the aluminium alloy cable with cross section allows is little, and the voltage of cable is increased, and the distance that electric energy reaches under limited voltage conditions is limited, and power supply area coverage is little, causes voltage cable to lose high.
3. antioxidant property is poor, and surface is very easily oxidized, makes contact resistance increase heating, accidents caused.
Therefore, aluminium alloy power cable over-all properties is still poor, along with the development of electric power material, also more and more higher to the performance requriements of aluminum alloy materials each side, needs high temperature resistant, that electric conductivity is high, lightweight, tensile strength is high novel aluminum alloy conductor material badly.
