Yoyu need some of these at the ends:

Simply tie them to your existing fence posts with enough room to prevent the hedge or fence earthing the live wires.

How long a fence are you running?

We run SPE2000's but run fences around 1.5-2kms

We've used electric fencing in the past but had one ewe who persistantly pushed through it to get to the better grass!  I think her fleece insulated her from the shocks.  The others never tried to get through it.

We've got electric netting, as long as you don't forget to change the fencer battery when it's going flat it does a good job of keeping our orphan bunch in  ;)  they haven't got stuck in it but it does deliver a good zap when they touch it... the poor dog didn't know what had hit her when she touched it for the first time!

Thanks Crazy Bull!  I wasn't aware of the existence of insulators - perfect!  Our fence is only going to be a max of 200m.  The guide you linked to recommends the SPE1000 for 3 strands of wire.  I wonder will it be sufficient for four strands?  I'm thinking it ought to be.  Can you tell me whether you can use rechargeable batteries with those units?  Mains power not an option! 

Thanks again.

I use standard 12v car batteries for most of my fences, however I only use them as I can get them for £10 from the local car breakers, they test them to check they will still hold a charge. If you have to buy new, buy a 'leisure' battery, these are designed unlike a car battery to be drained and recharged constantly, where as a car battery is designed for quick heavy use then instant re-charge, you will find car batteries die after a year or sooner and won't hold a charge. Best option if you can afford it is a leisure battery linked to a solar trickle charger, this will keep the battery topped up and may not need charging for a long time.

The SPE range that RAppa do have some nifty functions, like 2 different night modes, one that goes to half power at night and full power in the day, for daylight loving animals, and the other night time setting is half power in the day and full at night to stop the nocturnal animals. These are power saving options, it also has a function that tells you how much juice is left in your battery.

Any other questions just ask.

I would suggest lowering the bottom wires and even considering trimming the back of her neck a little bit when it warms up, if you have 2 strands at 10cm and 20cm she will get a shock on her head as she tries to get her neck under, when they have a full fleece on they only need to get their neck under and they are out, especially if using poly or stranded wire, (it stretches) it rarely happens with strained wire as it pushes through the wool to give them a shock.

Training on sheep is often best done against an existing fence line ( say a foot from the existing fence) that way they don't tend to push through and learn that the wire means ouch!

The SPE 1000 will certainly be enough for 4 strands at 200mtrs, probably even out to 500mtrs
