Why size of HT cable is less then LT cable inspite of the
fact that voltage is higher in HT cable?

Answer Posted / rainy

Hirer the voltage the lower the current. And the lower the
voltage the lower the current. Say for instance if you were
feeding the high side of a transformer with 230kv and the
sec. side was 100kv usually the size of conductors would be
(high side 1 mill. and on the low side would be 2 mill.
wire size usually dual conductors to carry the load on the
low side.
