yellow/black electric polywire for farm fence

Electric fences are designed to control animals by delivering a sharp electric shock.

Energizer converts power into high voltage pulse,one terminal connected to ground rod filled in the earth, another terminal from the energizer releases an electrical pulse along fence about once per second,the electrified fence itself must be kept insulated from the earth and from any materials that will conduct electricity(polytape,polywire,polyrope,netting) and ignite or short out the fence. Fencing must therefore avoid vegetation, and cannot be attached directly to wood or metal posts. Typically, wooden or metal posts are driven into the ground and plastic or porcelain insulators are attached to them, or plastic posts are used. The conducting material is then attached to the posts.
