As per IE Rules 1956,for EHT line the clearance above ground
of the lowest conductor shall not be less than 5.2 m + 0.3 m
for every 33000 V or part thereof by which the voltage
exceeds 33000 V ,provided the minimum clearance along or
across any street shall not be less than 6.1 m. So for 400
KV line, it works out to be 8.8 m

Answer / alap

ground clearence means the height of middle of line between
two towers from ground... it is so designed as the sag is
minimum and stress on transmittion line is also minimum....
