Why "at 75 degree centigrade"? Where & how it will encounter such extreme temperature?

I would assume the 75 degree C temperature is operating temperature of the overhead conductor rather than ambient temperature.

R2 = R1{ 1+α (T2-Tref)} Where: R2=Resistance at Temp. T2 (Can be your 75 Deg. C and Rref is the measure resistance at Tref Deg. C ( which is your 20 Deg. C) and α temperature co-efficeint fof Resistance at Tref(20) deg. C SO your Formula: R75= R20{1+α (75-20)} For Example: Copprer has α = 0.004041 R75= R20 * (1+0.22224)=1.22224 R20. α = 0.004041
