Barbed wire or razor wire shall not be electrified by an energiser. A non-electrified fence incorpo-
rating barbed wire or razor wire may be used to support one or more offset electrified wires of
an electric animal fence. The supporting devices for the electrified wires shall be constructed so as
to ensure that these wires are positioned at a minimum distance of 150 mm (6") from the vertical
plane of the non-electrified wires. The barbed wire and razor wire shall be earthed at regular
intervals. For safety reasons we recommend for offset fences only to use energisers with a maxi-
mum of 5 joules output energy. Follow our recommendations regarding earthing. See "Installing
and testing an earth system" on page 58.A distance of at least 10 m (33') shall be maintained
between the energiser earth stake and any other earthing system connected parts such as the
power supply system protective earth or the telecommunication system earth.
Connecting leads that are run inside buildings shall be effectively insulated from the earthed struc-
tural 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 fence wires shall not cross above overhead power or communi-
cation 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 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 fences
Power line voltage
> 1.000 ≤ 33.000 V
If connecting leads and electric 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 (7') for power lines operating at a nominal voltage not exceeding 1,000 V.
·
15 m (50') for power lines operating at a nominal voltage exceeding 1,000 V.
To prevent lightning damages you have to install lightning protection (spark gap with earthing)
in the leadout cable before you run it inside a building which is not liable to catch fire. Electric
