electrified fence

An electrified fence is a barrier with electricity running through it. Fences, in general, are erected to confine or exclude people or animals, mark boundaries, or for decoration.12

Historically, fences were made from materials like timber, soil, stone, and metal. Living plants, such as hedges and cactus fences, were also used. In North America, various timber fence designs were developed, including split rail and picket fences. In some regions, turf fences were built, which could last for years without heavy rain.2

Wire became a dominant fencing material in the mid-19th century with mass production techniques. Woven wire fences, attached to posts made of wood, steel, or concrete, offered a cost-effective and durable solution. The invention of barbed wire in the 1860s and its manufacturing machine in 1874 significantly improved the ability to fence cattle ranges.2

Electrified fences, often a single strand of barbed wire, are sometimes used for temporary animal confinement. They deliver a mild electric shock at intervals if an animal touches the fence.2
