Electric fence newbie- help needed

Hi all - I’m starting a food forest by planting 18 food trees and a 20x30’ vegetable garden. The whole space needs protection from our two major animal pressures, deer and bear. The space is roughly 100x100’x100’x100’ or a 1/4 acre. My budget is small but I want to do this right as well as cheap. I’ve read that a good electric fence or 3d electric fence will be my best bet. I understand some electric fence basics including the need for quality and quantity grounding rods.
Here’s where I need some help please. The area in question is about 300’ away from my off grid home and the closest source of power. I am most interested in using a 110v fence charger so I can get into the neighborhood of about 2.0 + joules on my budget and so the fence will be effective against deer and bear. I’d prefer to NOT run a strand of hot electric fence wire down the hill to the orchard but I think if push came to shove, I could certainly do that to make it work. However I have dogs and also care about the aesthetics. I’d much rather use some product designed to safely carry the current down the hill, like an insulated wire. In a perfect world I’d be able to bury that delivery wire. My thought is - since I plan on electrifying 2 strands at 400’ each for the perimeter, the charger should have no problem delivering the power through another 300’ of delivery wire or if needed - two delivery wires, one for each fence wire. I’d prefer to go up a size in AC chargers if needed rather than to deal with another solar panel and battery- not to mention I simply can’t afford a solar charger effective for deer or bear!  I hear of folks electrifying miles of fence so this seems doable in my mind but my internet searching has come up dry so far.
What kind of wire should I use for this “delivery wire”  to bring the power from the charger to the fence? Anyone ever done anything like this?
To summarize I want to use an AC plug-in high-joule charger and have it be located about 300’ from a pair of 400’ electric fence wires set up in a 3d configuration. What’s the best way to achieve this?

Welcome to Permies!

I do not have much electrical fence experience but I'm hoping this little bump of the thread will get someone with experience to chime in.

I’ll answer my own question for the record - in case anyone is ever searching and finds this thread. There is a product called insulated or even better, double insulated, wire. It’s meant for safely conducting electric fence charge and rated for burial. Typically used to connect to the ground rod(s) and also sometimes to connect fence lines to the charger. It can also be used as a lead line to bring the charge from an ac charger to a fence which is a little distance.
I ended up finding a solar setup with Parmak which fit budget and power requirements (3 joule). So I won’t get to test my idea but I’m quite sure it would work!

Hi Jay,
I'm glad you were able to find some information. It might be too late, but I would suggest going with the above ground wire to start with. I can't speak to aesthetics, other than the fact that people often get used to things after a little while.

Do you have any trees in that area or is it open? you could probably hang it like 10ft up, so it wouldn't effect the dogs or people at all. I just think it gives more flexibility. What happens if you want to move things around? or have a different setup? or decide you need a different gauge of wire? I would personally get it up and running for a couple years before putting in something as permanent as a 300ft underground wire. It's amazing how many things could change, and an above-ground wire is much much easier to replace or move.
