Perimeter I have mesh, one strand of electric tape on top to prevent/avoid leaning over. Divider was 3 strand, now one more on top, of electric tape. The high one needed because the two geldings fight about the mare in heat over the fence. Once the bottom- and once the second highest were ripped(kicking/rearing), no injuries, tape reconnected, horses even more respectful of fence.
When I used it with snow I disconnected what was buried, so still had hot wire without shorting out anywhere. Important is sufficient grounding, otherwise no juice. When dry, I pour water over the groundrods to keep the ground moist.
After using electric tape for over 20 years, I would not change. Even pretty wood or vinyl fence would have one strand hot....just to keep them OFF the fence.
