Q & A Interview With Gary Duncan of Powerflex :: Part Five

This is the big week that the fence goes up on our place. I can honestly say that I can hardly wait for this project to be done, but at the same time I feel a bit overwhelmed. Oh well, I guess we are just going to start regardless! One thing that I am confident of is that we will be in good hands with Gary Duncan of Powerflex helping us out. Check out the last two questions from my little Q & A interview with him and then check back all week long for the fence building progress.

7.) Lightening can be an issue with an electric fence. How can you handle that and are there other things that need to be considered.

Lightning is a powerful force. But, we can do things on the fence to try to get it to go ground prior to getting to your fence charger. Most larger energizers have two fuses in them – one for the fence side and another for the power supply side. A surge protector on the power side is also a device that will help. Some farms are more prone to lightning than are others. If your farm has historically had a lot of lightning hits, then multiple devices on the fence may be in order. There are different types of lightning protection devices, but most work somewhat in the same way. Either there are contact points or a spark gap that will activate when a surge of lightning attacks it. Some have coils. The coil is a device that aids in defusing and slowing down the flow of lightning thus encouraging it to make the spark gap in the device. It is generally recommended that you install one more ground rod at your lightning protection than you did at the energizer. Ie: you have 4 ground rods at the energizer, you should have 5 at your lightning protection. This device should be installed 65 feet away from your energizer grounds. No device is guaranteed to stop lightning entirely but it is worth the effort to try.

8.) So, how does this whole process go together in a nutshell? Is it a fairly difficult process or something that someone can get the hang of as they work?

If you are just starting out with electric fence I would recommend that you read up as much as you can. There is much information on the internet about electric fencing. I don’t think that electric fencing is difficult, but you do need to think it out as you build your fence. Hi-tensile wire is relatively easy to work with. Wire usually comes in 4000’ coils (with a weight of 100#’s) and you’ll need a wire dispenser, also called a spinning jenny to roll out your wire. Never try it without one! You can either crimp your joints and connections or you can hand knot them. If you crimp, you will need a good crimp tool. Even if you hand knot, there are still places that you will need to crimp. Hand knotting is not really all that hard to learn, however, only practice makes perfect. Once you learn how to tie hand knots, you will not need to carry many tools around with you as you build fence.
