Description
Technical field
The utility model relates to a kind of cable, especially relates 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 get into and forms oxide-film, makes contact resistance increase and overheated, 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.
The utility model content
The purpose of the utility model 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 compressing property height, tensile strength height, yield strength is high, elongation is high, springback capacity is little, memory-less effect, aluminium alloy cable easy for installation.
The purpose of the utility model can realize through following technical scheme:
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 up of the insulating barrier of aluminium alloy conductor and aluminium alloy conductor outerwrap.
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 utlity model has following advantage:
(1) electric conductivity is good: 8030 aluminium alloy conductors are compared with fine aluminium (1350) cable, have significantly increased copper/iron/magnesium elements, and are well-known; 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 through technology controlling and process;
(2) creep resistance has improved 300% with compressing 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 the 8030 aluminium alloy cables of the utility model is 53MPa;
(4) special processes process makes 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 is merely 7 times of external diameters, is more convenient for building interior use.
