Aluminium alloy is used to have the advantage that as conductor material
Creep-resistant property aspect
The alloy material of aluminium alloy conductor and annealing treating process decrease conductor and are being heated and " compacted under pressure
Become " tendency, relative to fine aluminium, creep-resistant property improves 300%, it is to avoid owing to cold flow or creep cause
Relaxation problem.
Tensile strength and elongation percentage aspect
Aluminium alloy conductor is compared to fine aluminium conductor, owing to adding special composition and have employed special processing
Technique, greatly improves tensile strength, and elongation percentage brings up to 30%, uses more safe and reliable.
Thermal coefficient of expansion aspect
Thermal coefficient of expansion is used for calculating the change in size of material when variations in temperature.The thermal coefficient of expansion of aluminium alloy
Suitable with copper, aluminum adapter is reliably used for copper and aluminium conductor, and the current major part used always for many years
Electrical cnnector is all constructed of aluminum, and this is especially suitable for aluminium alloy.So aluminium alloy conductor and adapter
Expand and shrink completely the same.
