FACTORS TO CONSIDER
IN SELECTION OF CONDUCTOR:
Materials
Types
Factors to consider
Physical
Mechanical
Electrical
oConductor diameter
oWeight per unit length
oConductivity of material(s)
oCross sectional area(s)
oModulus of elasticity
oRated breaking strength
oCoefficient of thermal expansion
oCost of material
oMaximum unloaded design tension
oResistance to vibration
oSurface shape of drag coefficient
oFatigue resistance

Design
These necessarily are NOT
independent to one another.
