We're planning to install an electric fence at the orchard during the next two weeks. It will be positioned outside of the recently laid hedge on the field side of the orchard. The wire fence at the road side will not be electrified. The fence will be of a semi-permanent construction running for approximately 100 metres, with wooden posts spaced at 10-15 metres. There will be temporary green plastic push-in posts supporting the wire between the wooden posts. Once the hedge has grown strong enough to repel browsing farm animals the fence will be removed.
The fence will be built using five strands of galvanised braided wire (1.6 mm) and a top strand of white poly-electric fence rope. The fence design is is aimed to prevent sheep from damaging the hedge or the fruit trees in the orchard. They did a lot of damage last winter.
The fence will have a powerful charge capable of penetrating the insulating wool of the sheep, probably in the region of 8000V. It is about twice the power needed for a electric fence configured for horses/cows. While the charge on the fence is not dangerous it would be very unpleasant for you if you touch the fence and get a shock. It would be similarly unpleasant for a dog.
We'll be labelling the fence according to the regulations. It will be possible to access it from the public footpath if you wander off the path and trespass into the farmer's field. However it will not affect access to the public path.
