Feature & description of polymer insulator
• Composite Post Insulator with Porcelain Core is consist of porcelain core, sheds and metal fitting. The inner insulation is made of high-strength porcelain by isostatic pressing processing technology, and bear the whole mechanical load in the running. Shed is made of composite material and the raw material is silicone rubber by the high-temperature injection technology.
• polymer insulator has provided insulation and necessary creepage distance, to ensure the composite post insulator running long-term and safety in the atmosphere environment. When the porcelain insulator breaks due to the brittleness, the wrapping to porcelain core by shed can reduce the harmful influence to the workers at working site and other electrical equipments around.
