JVA AgriRange Energizers
6. The
energizer earth electrode
shall penetrate the ground to a depth of at least 1.2 m.
7.
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.
8.
Connecting leads
that are run underground shall be run in a 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 tractor wheels sinking into the
ground.
9.
Connecting leads
shall not be installed in the same conduit as the mains supply wiring,
communicating cables or data cables.
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 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.
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 5 below.

Minimum Clearances from Power Lines
13. if connecting leads and electric animal fence wires are installed near an overhead power
line, their height above the ground shall not exceed 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.
