Electrical insulator is a very important component in the electric power systems such as sub-stations and distribution & transmission lines. In the early days, insulators were made of ceramic and glass materials. But in 1963, polymer insulator was developed it is consist of a fiberglass core rod covered by weathersheds of skirts of polymer such as silicone rubber, polytetrafluoroethylene, EPDM (ethylene propylene diene monomer) and equipped with metal end fittings. It is also called composite insulators, which means made of at least two insulating parts a core and housing equipped with end fittings. Polymeric insulators have many advantages over the ceramic and glass insulators such as good performance in contaminated environment, light weight, easy handling, maintenance free, and considerably low cost etc.
There are many types of polymer insulator. Polymer suspension insulator; composite pin insulator;polymer station post insulator; composite line post insulator etc.
