Polymer insulators, composite insulators

Now, polymer insulators were welcomed by many countries. If you go to the seaside tourism, looked at the sky and you will find that the pole will have many composite insulators. It gradually replaced the ceramic insulator.

Polymer insulators, composite insulators

Electrical insulator is an important part of the electric power systems such as station and distribution lines. In the early days, insulators were made of ceramic and glass materials. But in 1963, polymer insulators were developed. Polymer insulators are Improvement in design and manufacturing in the recent years have made them attractive to utilities. Polymer insulator is consist of a fiberglass core rod covered by sheds of skirts of polymer material such as silicone rubber, EPDM (ethylene propylene diene monomer) and equipped with metal end fittings. Polymer insulator is also called composite insulator, which means made of at least two insulating parts – a core and housing equipped with end fittings.

Polymer 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 polymer insulator is gaining popularity worldwide and replacing the conventional ceramic and glass insulators.

Now, polymer insulators are welcomed by more and more buyers, they are particularly suitable for highly contaminated areas. We offer all kinds of polymer insulators, if you need, please contact with us.
