Why do we need insulators?
We use insulators so that the bare metal fence wires do not touch the steel rods that are hammered into the ground for support. The ”insulators” are plastic which is non-conductive.
We ran 5 wires as was recommended in a article I read online. If you are using electric fences to keep predators out of an area, 5 wires are suggested alternating between positive and negative. It is also sugegsted to start with a positive on the top and end with one on the bottom.
After we ran the 5 wires around the perimeter, I started to tension them up. The rebar bent in towards the center of the area the fence was surrounding as I tightened! What was I thinking????
I was hoping the rebar would work, and was originally planning on using the 15mm rather than the 10mm diameter. I went back to the hardware store and bought 4 seven foot fence t-bar. My only worry was if I would be able to get them hammered into the ground.
I pulled the rebar out and inserted the pointy end of the tbar into the hole from the rebar. After some serious hammering the tbar went down about 2 feet into the ground leaving about 5 feet exposed. T-bar by design is much more resistant to flexing than rebar. It should have been my first choice I guess. Tomorrow I will energize the 5 wires and hopefully it will keep bears from having a snack.
