There are various components of an electric fence that are joined together to come up with an electric fence system. A farm electric Fences in Kenya will most likely use treated wooden posts or in cases where the soil is too wet or there is a large infestation of termite, steel posts can be used.
Treated Wooden Posts-strainers for use on Electric Fences in Kenya
