Answer Posted / venkatgopal
because in america the machinces are constructed with 60 hz
frequency and another reason is america is ecnomically
better than the india so when freqency is high the power
transmisson is at high rate and loosses also high.when they
are economically good so for redusing the looses they are
using good insulaters
