It is a big mistake to put a steel post anywhere into an electric fence, because then you rely on the insulator to keep your cattle fence from shorting out.
Tianze prefers highly flexible plastic or wood-plastic composite posts, “No matter how good an insulator you get, eventually something's going to break or pop off, and you have the potential for dead-shorting.”
So in short, if you want a reliable electric fence you can break it down to these seven tips -- and that's everyone's goal, right?
1. Corner posts are the correct location and size.
2. Fence columns need to spaced 50-100 feet apart.
3. Using the right energizer. Tianze suggest 1 joule of output per mile of fence.
4. Put your ground rounds far enough apart.
5. Make cattle fence flexible to keep it wildlife friendly.
6. It is a challenge to creat a gate system that conducts current, instead trench the fence underground.
7. Don't use steel columns, instead use flexible plastic or composite posts to prevent shorts.
