Are you building a permanent electric fence with wooden posts? These insulators got you covered. The insulators are built to have the least resistance, so you fence keeps its juice over its distance. The insulators are easy to install with the screw in technology. 

These ring insulators are built without a metal core. The most important reason for this is to prevent short circuits when the insulator wears down. All ring insulators wear down over time. When there is plastic in the core of the insulator. The conductor will touch this and the fence will loose all it's power from this point. If you are looking for ring insulators which wear down realy slow, without the risk of short circuits? Have a look at the Gallagher XDI insulators.
