10 H.P = 10.25 Amps
IN CASE ALUMINIUM CONDUCTOR USE CONSTANT VALUE IS =0.75
IN CASE COPPER CONDUCTOR USE CONSTANT VALUE IS =1.25

SO CONDUCTOR SIZE+cable sqmm *075 =10.25amps, now a days increase current so cable size is small size increases.
10.25*0.75=10 sq mm

what is the criteria for selection of conductor used for ehv ac electrical dischrge
