10.
Connecting leads
and electric animal fence wires shall not cross above
overhead power or communication lines.
11. Crossings with overhead power lines shall be avoided wherever pos-
sible. If such a crossing cannot be avoided, it shall be made underneath
the power line and as nearly as possible at right angles to it.
12. If
connecting leads
and
electric animal fence
wires are installed near
an overhead power line, the clearances shall be not less than those
shown in table 3.

13. If
connecting leads
and
electric animal fence
wires are installed near
an overhead power line, their height above the ground shall not ex-
ceed 3m. This height applies either side of the orthogonal projection
of the outermost conductors of the power line on the ground surface,
for a distance of
•
2 m for power lines operating at a nominal voltage not exceeding 1,000
V
•
15 m for power lines operating at a nominal voltage exceeding 1,000 V.
