Watergap Project

Plenty of ways to do this, but here is one, this gap is made of standard cattle panels pieced together, hung from 12ga hi-tensile wire with an inline strainer.  The gap is electrified on both sides using Dare Western Insulators and 11ga Tie Wire.  The two sides of electric are joined by 14ga Dare Underground Wire so that it doesn't short out if it touched the panel. 

Not used here but there is a device to cut the voltage if the wire is underwater or grounding heavily.
