Question #783

What is the safe distance between a crane or its load and the outermost conductors of a power line with a nominal voltage above 110 kV?

Jaka jest bezpieczna odległość żurawia lub ładunku od skrajnych przewodów linii elektroenergetycznych o napięciu znamionowym powyżej 110 kV

a
10m

10m

b
15m

15m

c
5m

5m

d
30m

30m

Correct answer

Why?

For voltages above 110 kV, the safe distance (bezpieczna odległość) is at least 30 m horizontally from the outermost conductor to the nearest part of the crane or load. The 15 m clearance applies to voltages above 30 kV and up to 110 kV.
