Minimum distances from any building or structure to any position to which a conductor in an overhead line may swing under the influence of wind shall be as specified below
|Nominal Voltages||Vertical Distance||Horizontal Distance|
|Not exceeding 1000 Volts||2.40 m||1.50 m|
|Exceeding 1000 Volts but not exceeding 11,000 Volts||2.70 m||1.50 m|
|Exceeding 11,000 Volts but not exceeding 33,000 Volts||3.00 m||2.00 m|
|Exceeding 33,000 Volts but not exceeding 132,000 Volts||4.10 m||4.10 m|
|Exceeding 132,000 Volts but not exceeding 220,000 Volts||5.18 m||5.18 m|
The regulation also specifies the limits of the height above the ground that should have between an overhead line is over or along a road or over any other location accessible or inaccessible to vehicular traffic.
