Because of its large tensile strength,light weight,corrosion resistance,good sagging performance,all aluminum-alloy conductor(AAAC) are widely used in many countries.

Development and study of all aluminum alloy conductor with high strength and heat-resistance;

Heat-resisting Aluminum Alloy Conductors Mechanics Performance Calculation;

In this paper the heat withstanding mechanism of heat-resisting aluminum alloy conductor is discussed, the types and performance of the conductor and its application on transmission lines are analyzed and introduced, and suggestions on accelerating exploitation and application of the conductor are put forward.

Taking several just finished capacity-increasing engineering projects as an example,the paper introduces and compares application,characteristics,economic performance of heat-resisting aluminum alloy conductor,ACCC,ACCR,summarizes the application experience of these new type conductors.
