Table 2

Distances for spans more than 150 metres in length

Length of span
(metres)
Vertical distance from a horizontal plane drawn from any point on conductor
(metres)
Horizontal distance from a vertical plane drawn from any point on conductor
(metres)
150 to 3004D1 = 4
D2 = 8
301 to 5004D1 = 7.5
D2 = 15
501 to 7004D1 = 15
D2 = 30
Greater than or equal to 7014D1 = 25
D2 = 50
Key:
D1 = distance for the 15% of each span at either end of the span
D2 = distance for the centre 70% of each span
