Electric fencing poly wire, poly braid, poly rope and poly tape.
For high visibility use polytapes or thicker poly ropes, use polywire in windy areas and poly braid where a bit of extra strength is required. Standard polywires and tapes will generally fence about 500m before you lose the zap in the fence. For greater distances use the Hi-shock range which has 3 times less resistance than standard polywires and tapes.
