- 17. Conductor FACTORS TO CONSIDER IN SELECTION OF CONDUCTOR: Materials Types Factorsto consider Physical Mechanical Electrical o Conductor diameter o Weight per unit length o Conductivity of material(s) o Cross sectional area(s) o Modulus of elasticity o Rated breaking strength o Coefficient of thermal expansion o Cost of material o Maximum unloaded design tension o Resistance to vibration o Surface shape of drag coefficient o Fatigue resistance Design These necessarily are NOT independent to one another.

- 19. Conductor DESIGNS OF CONDUCTORS • AACSR (Aluminum Alloy Conductor Steel Reinforced) • Expanded ACSR • Smooth body conductors *trapezoidal shaped wire conductors *compact conductors • VR Conductors • Self Damping Conductors • Bundled Conductors • Surface Finishes Materials Types Factorsto consider Design With each change, there is a compromise. With each compromise, there is a new design.
