Abstract: An electrical conducting rope for use on electric fencing of livestock with an inner core of stranded conductor cable and an outer insulating layer of braided synthetic fiber filaments. The inner core is formed of seven cable strands, each formed of seven twisted galvanized wires. The outer layer is formed of a braid of multiple polyester filament carriers. The carriers have contrasting colors to provide high visibility of the electric fence. A standard electric fence charger connected to the inner conductor core provides electric shocks to livestock contacting the outer insulating layer. The outer layer may have gaps in the braiding to expose the inner conducting core below the surface of the outer layer.
