I have a Gallagher solar charger with that soft alum wire. I'd like to put stronger wire up. I saw barbless wire the other day and though to replace it with that. Does the barbless conduct well?
Kjerckie 12 quage Hi tensile wire is good .I have seen guys fence in bison with it.The keys are a good ground, good wire ,adequate fencer and a digital volt meter. We also use a lighting choke on the fencer.
We put in6- 8 inch 10 -12 ft cornerposts, 4 ft in the ground.Then space out the post 35-60 feet apart, depends if the ground is rolling or not insulators on all wires. 3 hot wires for cattle /5 for sheep (3 hot 2 ground.)We have it set up so we can switch some wires to a positive/ ground system if we need.My ground for our main fencer is in a slough.The moist ground helps.
BtW Speedrite has a really good handout book on electric fencing.
Good luck with your project.
