Description
Technical field
The present invention relates to electrical distribution field, specifically provide the aluminium alloy power cable of a kind of high-performance, low cost.
Background technology
Aluminium is the metal that in the earth's crust, content is the abundantest.In earth's crust gross mass, aluminium accounts for 8%, and iron accounts for 5%, and copper accounts for 0.0001%.And the copper resource of only 0.0001% is just being widely used in the every field of society in this earth's crust gross mass with immeasurable speed, comprise all many-sides such as electric power conveying, water conservancy pipeline, heat sink applications, therefore the resource day of copper metal shows in short supply, cause copper metal price to rise steadily, cause the project cost such as present building constantly to rise.Therefore correlative technology field technical staff is badly in need of a kind of new technology of copper power cable that can replace and is occurred, replaces copper can be the strategy of a long-run development with aluminium.With regard to resource, as in the metals resources of cable conductor, aluminum ratio copper has absolute predominance; With regard to manufacture view, the cable of a same length, required aluminium important also comparatively lighter than copper, generally can light 0-50%, therefore, in whole transport and installation process, also for client brings the effect of energy-conserving and environment-protective.With regard to economic development, reduce costs expenditure angle, aluminium cable has the more powerful market space than copper cable.
But the index such as conductivity, thermal endurance, creep resistance, tensile strength of the aluminium alloy power cable that prior art is produced and copper alloy power cable have a certain distance, and key property can not meet the demands in electric power transmission industry.
Summary of the invention
For the deficiencies in the prior art, an object of the present invention is to provide a kind of high-performance, the aluminium alloy power cable material of low cost.
Technical scheme of the present invention:
A kind of aluminium alloy power cable, it is characterized in that, described aluminium alloy power cable chemical composition comprises: (mass fraction, %): Si:0.01 ~ 0.30; Fe:0.5 ~ 1.3; Mn:0.01 ~ 0.05; Cu:0.03 ~ 0.05; Mg:0.01 ~ 0.5; Zn:0.01 ~ 0.09; Ca:0.1 ~ 0.5; (V+Ti+Cr+Ni+Co+Zr): 0.005 ~ 0.20; E:0.01 ~ 0.06;
Wherein E element is the one of B, Be or 2 kinds;
Surplus is Al and inevitable impurity.
Preferably, the content summation of described Mg and Zn is no more than 0.45.
Preferably, described aluminium alloy power cable monomer has following performance:
Tensile strength 190MPa ~ 250MPa; Conductance is more than or equal to 61%IACS, percentage elongation 20% ~ 40%.
Preferably, described aluminium alloy power cable monomer has following performance:
Conductance is more than or equal to 62%IACS; Average creep speed to be less than etc. 5 × 10
-2%/h; Tired bending number of times is more than or equal to 15.
Performance and the effect of related component are as follows:
Si:Si element add intensity when can improve aluminium alloy tensile strength, hardness and high temperature.
Fe:Fe element add the mechanical strength and tensile property that improve aluminium alloy, improve high-temperature creep resistance and the anti-fatigue performance of aluminium alloy;
Adding of Mn:Mn element improves elevated temperature strength, alleviates the problem that corrosion resistance is low;
Cu:Cu element add high temperature anti-fatigue performance, high-temperature creep resistance and the mechanical strength that can improve aluminium alloy, increase the resistance stability of aluminium alloy when high temperature;
Adding of V, Ti, Co, Cr, Ni, Zr has also been carried out supplementing further to the creep resistance performance of aluminium alloy power cable, also improves the thermal endurance of aluminium alloy;
Mg and Zn:Mg and Zn element add the mechanical strength strengthening aluminium alloy, too can not reduce again the corrosion resistance of aluminium alloy power cable containing quantitative limitation to Mg and Zn;
E:E element is the one of B and Be element or 2 kinds, B and Be element add the processing characteristics improving aluminium alloy, improve antioxygenic property.Especially in containing the aluminium alloy of zirconium, add appropriate B, B can improve its conductivity under the prerequisite ensureing alloy thermal endurance.
Beneficial effect of the present invention:
Aluminium alloy formula material adapted of the present invention is reasonable, and element is mixed by a certain percentage and makes aluminium alloy have good combination property, namely conductivity is high, thermal endurance is high, creep resistance is strong, tensile strength is high.Meanwhile, the manufacturing cost of aluminium alloy is also lower, has good economic benefits.
The present invention has the clear superiority of light weight.Under the prerequisite meeting equal electric property, weight of the present invention is the half of copper core cable, owing to alleviating the own wt of cable, therefore in the middle of the processes such as transport, installation, laying, invisible or visibly considerably reduce operation cost, energy-conserving and environment-protective, improve economic benefit.In addition, under the prerequisite meeting equal electric conductivity, cross section of the present invention is about 1.5 times of traditional copper core cable, but self price is only copper core cable 50% ~ 60%.Use aluminium alloy cable of the present invention to replace copper cable, can cable weight be reduced, reduce installation cost, reduce the wearing and tearing of equipment and cable.
