The origin of polymer insulators

Electrical insulators are a very important component in power systems such as substations and distribution and transmission lines. In-depth research and practical knowledge on the subject is Required for electrical professionals in the power field. In the early days, insulators Made of ceramic and glass materials. But in 1963, polymer insulators were developed, and their Improvements in design and manufacturing in recent years have made them attractive to utility companies.

It consists of a fiberglass core rod covered with a weatherproof skirt of a polymer such as silicone Rubber, PTFE, EPDM (ethylene propylene diene monomer) and equipped Metal end fittings. Composite insulators, also known as composite insulators, refer to insulators made of at least two layers of insulating materials. Parts – Core and casing with end fittings. Polymer insulators have many advantages Better than ceramic and glass insulators, such as good performance in polluted environments and light resistance Light.
