why are we adopting 132kv,220kv for transmission rather than using 440kv at all transmission lines as it gives lower losses?

Answer Posted / prashant shinde
beacause transfomer principal to incrase the voltage the
current down the current down thickness of conduter down or
size of wire down,but if we icrease the voltage upto 440kv
the hight of pole of the transmision line will be requred
to increase because static charge of 440kv will be more
than 132kv & 220kv.hance the transmision cost increases.
