Answer / k.prakashchandra

The minimum ground clearance depends upon voltage
only.1)Across the road a)low and medium voltages- 5.8mt
b)high- 6.1 mt2)Along the road a)5.5 mt b)5.8 mt 3)
Elsewhere a)low,medium high voltages up-to 11 KV ,if bare
-4.6 mt 2) if insulated- 4mt c)for high voltages above 11 KV
-5.2 mt 4)extra high tension 5.2 mt + 0.3 mt for every 33 KV
or part thereof by which the voltage exceeds 33KV,provided
that the minimum clearance along or across the road shall
not be less than 6.1 mt .Low voltage - up-to 250,medium
-up-to 650,high-up-to 33KV ,extra high -above 33 KV. Ref IE
Rules 1956
