How many pigs are you managing is the first important question..?
Joel Salatin in the US has 50 in half acre paddocks for about a week at a time. He sets out ten paddocks and keeps the pigs moving.
Give your pigs room to move - even if there are just two or three. Set up a number of paddocks next to each other and get them used to moving.
Keep the wires tight, keep them parallel to the ground. I tap in old fence posts at the corners and tie band around the electric posts to keep them from bending in.
I use Hotline posts along the sides. At the corners I use Gallagher posts - they have hooks to stop the wires jumping off the post under tension.
Start with three wires. I use three (I've got plenty of the stuff).
Put one low down, make sure one is at pig eye height. Watch them to see where their eye is at. A pig will try to go under wires whereas cattle and sheep would jump.
A strimmer/brush cutter is useful to cut the grass that'll earth on the lowest wire.
Plan a e-fence gate to make it easy to move paddock to paddock. I've seen places use a wooden gate with wires either side. I reckon mine would push the wooden gate over. When I move the pigs I entice them past the (removed) zap with food.
Use decent leisure/marine batteries, change them before they're flat and get a cheap fence tester. Make sure you have a good earth rod wacked well in the ground. In dry weather, when you give the pigs drinking water, wet the earth at the same time.
Make sure to stand and watch when you let the first gang in.
