Compared with the prior art, the aluminum alloy cable has the advantages of high conductivity, high creep and compaction resistance, high tensile strength, high yield strength, high elongation, small springback value, no memory effect, easy installation and the like.
Description
Technical field
The present invention relates to a kind of cable, especially relate to a kind of aluminium alloy cable.
Background technology
The aluminium cable that uses in the Building Trade in China, its material are fine aluminium.Its shortcoming is: creep-resistant property is poor, can cause creep by expanding with heat and contract with cold of causing of energising outage in the junction, can relax after long-time, and the thrust of bolt diminishes relatively, contact resistance increase and cause overheated, accidents caused at last.The bolt material that terminal is connected with equipment or busbar is uneven, or even iron bolt, and the coefficient of expansion of metal material is different, and does not add when mounted and shoot pad, causes air to enter the formation oxide-film, and is overheated so that contact resistance increases, and also is hidden danger.The used terminal of fine aluminium cable is without special processing, may produce electrochemical corrosion with the junction of copper bar.
Summary of the invention
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists that a kind of electric conductivity is high, creep resistance with the compression height, tensile strength is high, yield strength is high, elongation is high, springback capacity is little, memory-less effect, aluminium alloy cable easy for installation.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of aluminium alloy cable, comprise band, sheath, insulated wire cores and inserts, band is wrapped with sheath, is provided with insulated wire cores in the band, inserts is located in the slit between insulated wire cores and band, and described insulated wire cores is made of the insulating barrier of aluminium alloy conductor and aluminium alloy conductor outer wrapping.
Described insulated wire cores is three or four.
Described aluminium alloy conductor is 8030 aluminium alloy conductors.
Described 8030 aluminium alloy conductors comprise the component of following weight content:
Surplus is aluminium and inevitable other elements, and wherein other element total contents are 0.20.
The resistivity of described aluminium alloy conductor is 61%IACS, and tensile strength is 56～111Mpa under the soft state, and density is 2.71g/cm3, and percentage elongation is 15～25%, and annealing temperature is 300～350 ℃.
Compared with prior art, the present invention has the following advantages:
(1) electric conductivity is good: 8030 aluminium alloy conductors are compared with fine aluminium (1350) cable, significantly increased copper/iron/magnesium elements, as everyone knows, after in aluminium, adding other multiple alloying element, electric conductivity can descend, and 8030 aluminium alloys make conductance be returned to the level of fine aluminium by technology controlling and process;
(2) creep resistance has improved 300% with compression property, has avoided because the relaxation problem that creep causes;
(3) tensile strength is high: the drawing strength that common aluminium cable allows is 40MPa, and the drawing strength of 8030 aluminium alloy cables of the present invention is 53MPa;
(4) special processes process is so that 8030 aluminium alloys have higher yield strength than fine aluminium cable, and elongation has improved 30%, and springback capacity is little, memory-less effect;
(5) easy for installation: 8030 aluminium alloy cables adopt the self-locking sheathed structure because unique alloy formula, processing technology added, flexility significantly improves, the bending radius of general aluminium cable is 10～20 times of external diameters, and the bending radius of 8030 aluminium alloy cables only is 7 times of external diameters, is more convenient for building interior use.
