Composite insulator,suspension composite insulator for high strength
Suspension composite insulator for high strength has high tensile strength as like composite long rod insulator. Composite insulator has other characters, such as section length, creepage distance and so on.
Composite insulator history:
Electrical composite insulator is a very important component in the electric power systems such as sub-stations and distribution & transmission lines. In-depth study and practical knowledge on insulator subject is necessary for the electrical professionals in the electrical power field. In the early days, insulators were made of ceramic and glass materials. But in 1963, composite insulators were developed and its improvements in design and manufacturing in the recent years have made them attractive to utilities.

Suspension composite insulator for high strength formations:
Suspension composite insulator for high strength is consist of a fiberglass core rod covered by sheds of skirts of polymer such as silicone rubber, polytetrafluoroethylene, EPDM (ethylene propylene diene monomer) and equipped with metal end fittings. It is also called polymer insulators, which means made of at least two insulating parts – a core and housing equipped with end fittings. Composite 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. Because of these properties it is gaining popularity worldwide and replacing the conventional ceramic insulator and glass insulators.
