Polymeric insulators have many properties and their specifications is important and as per standards.

Polymeric insulators crossarm types specifications:

These polymeric insulators are applied to urban net technical reconstruction; it can effectively boost power transmission using urban narrow corridor areas, lower tower height, save many pecuniary resources and materials. Because of the high bending strength, Polymeric insulators can avoid the porcelain insulators having continuous fracture accidents easily, with good anti-pollution, and the products of porcelain insulators cannot be instead of them.
