Question:

what is the size of the AC SR Conductor at 11 KV for 150 HP motors at ambient temparature of 45 deg C max?

the above details are meant for a 3 KMs line length 3 phase

Answer:

150 HP motors has a full load current of 180 amperes at 460 Volts. This is 7 plus amperes at 11 kv. Cm = 1.732(22)8(3,000)(3.28)/.03*11000 Cir Mils =9984 You will need a 1/0 ACSR as supply conductor.
Squirrel conductor is good enough up to 3 KM length.
