Factors toconsider
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
