Datamars 46000W Mode D'emploi page 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.
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
≤1000 V
>1000 V to ≤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 (6'6") for power lines operating at a nominal voltage not exceeding 1000 V.
•
15 m (50') for power lines operating at a nominal voltage exceeding 1000 V.
•
Electric animal fences intended for deterring birds, household pet containment or
training animals such as cows need only be supplied from low output energizers to
obtain satisfactory and safe performance.
Clearance
3 m (10')
4 m (13')
8 m (27')
