Connecting leads that are run inside buildings shall be effectively insulated from the earthed
structural parts of the building. This may be achieved by using insulated high voltage cable.
Connecting leads that are run underground shall be run in conduit of insulating material or
else insulated high voltage cable shall be used. Care must be taken to avoid damage to the
connecting leads due to the effects of animal hooves or vehicle wheels sinking into the ground.
Connecting leads shall not be installed in the same conduit as the mains supply wiring,
communication cables or data cables.
Connecting leads and electric animal fence wires shall not cross above overhead power or
communication lines.
Crossings with overhead power lines shall be avoided wherever possible. 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.
If connecting leads and electric animal fence wires are installed near an overhead power line,
the clearances shall not be less than those shown in the table below.
Minimum clearances from power lines for electric animal fences:
Power line voltage
≤ 1.000 V
> 1.000 V bis ≤ 33.000 V
> 33.000 V
If connecting leads and electric animal fence wires are installed near an overhead power line,
their height above the ground shall not exceed 3 m (10'). This height applies to 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 1000 V.
• 15 m for power lines operating at a nominal voltage exceeding 1000 V.
