Electrical – Can stranded wire handle the same high voltage as solid core

electricalfencewire

Two 10 AWG wires for an electric fence were cut by the lawn mowers. I read that electric fences have very low amperage. So a 30 A rating is well above the call of duty: 10-2 type UF-B cable with ground wire (stranded).

That is what's available locally. There is no voltage rating. Although, looking online, I find that similar stranded wires have 1000 VDC (TÜV). Does that mean they're rated only up to 1000 VDC? Or is this just something to do with solar panels?

Edit – This wire is between the energizer and the fence, no man's land.


Aside, why does our electric fence have two wires? To create an open circuit, wouldn't you only need one?

No, you'll need the proper electric fence extension wire

The problem with a standard UF or equivalent cable is that the insulation is only rated for 600V, far less than the several thousand volts that an electric fence energizer puts out. As a result, you'll need a specialized electric fence extension wire and matching splices that are rated for such high voltages to replace the damaged wire. Using the wrong stuff will cause the wire insulation to break down and fail, leading to your fence grounding out.
