Hybrid Insulators – Another Solution for Improved Performance
PPC INSULATORS began the development of Hybrid post insulators after realizing the needs for high strength, low deflection under loads for many applications as earthing switches – disconnectors – reactors, and busbar supports. Based on the very positive historical experience with solid core porcelain post insulators and the pollution experience of insulators with silicon rubber housings the fundamental concept of both has been used in this development. The challenge was to provide a reliable and economical solution, which combines the superior mechanical advantages of solid porcelain and the electrical advantages of silicon housing for high pollution requirements. The challenge was to provide a reliable and economical solution, which combines the superior mechanical advantages of solid porcelain and the electrical advantages of silicon housing for high pollution requirements.
This paper presents the experience of PPC Insulators in developing, designing, manufacturing, testing, and application of post insulators – made of ceramic and silicone – Hybrid post insulator with a ceramic solid core.
