The function of aluminium alloy cable and aluminous core cable is comparative

The function of aluminium alloy cable and aluminous core cable has sure distinction, of aluminium anti-corrosive the function is better than copper, but of aluminium alloy anti-corrosive the function compares aluminium more actor. Below we from anti-corrosive function, mechanical function, electric ability, fight 4 respects such as creep function undertake analysing.

One, anti-corrosive function
Of aluminium anti-corrosive the function is better than copper, but of aluminium alloy anti-corrosive the function compares aluminium more actor, because aluminium alloy is medium what the chemical element such as the rare territory that enter can increase aluminium alloy is anti-corrosive function, be able to bear or endure especially electrochemistry corrodes a function, handled aluminium to handle the question that the electrochemistry that appear corrodes for long in contact.

2, mechanical function
Head of a list of names posted up, tensile strength and outspread rate. Aluminium alloy conductor compares Yu Chun aluminous conductor, because attended special class status to use special processing technique, huge increased tensile strength, and outspread rate rises 30% , handle on the safe side of all the more.

The 2nd, labyrinthian function. The labyrinthian function of aluminous core cable is very poor, produce craze very simply zigzag, the labyrinthian radius of cable of aluminium alloy power is external diameter of 7 times cable, far of excel GB/T12706 " the smallest labyrinthian radius when cable unit " in regular 10 times - external diameter of 20 times cable.

The 3rd, withy function. Aluminium cable wants the change of sure viewpoint a few times only, conductor can present craze or break off, easy cause disturbance, and the turn that cable of aluminium alloy power can endure a few times is folded, eliminated before aluminium cable unit manages the risk that disturbance presents in the process, improved function of on the safe side greatly.

3, electric ability
Aluminium alloy conductor is the element such as rare earth, magnesian, copper, iron adds in aluminium, carry the new-style conductor material that alloy technology makes. Known to all, other joins in aluminium after a variety of alloying element, electric function can drop, and control through the technology, can make conductivity restores to get close to the level of aluminium, make its and aluminium have the current-carrying capacity of close.

4, fight creep function
Aluminium fights creep function difference, the heat that breaks conductance to send by electrify bilges cold shrink in join place can cause squirm variable big, can appear for long later lax, feeling resistor increases and bring about overheat, cause disturbance simply. 300% the denaturation fighting squirm of AA8000 series aluminium alloy is aluminium conductor, reduced the possibility with cable lax connect greatly, improved conductor join circumstance.
