various types of material used as per requirement like AAAC,
ACSR, ACSS etc.
by calculating per phase current (which is smaller value)
with 33/66/132 kV line, its impedance is calculated first
and then simply according to ohm's law,
size of conductor:
V/I = (resistivity * length)/ (area of cond.)
thus area and diameter can be calculated. on internet
standard tables for size of cond is available.
