PolHR Series Hybrid Pin Insulators

Hybrid insulators combine the best features of ceramics and polymers. A ceramic core provides high mechanical strength and rigidity while a hydrophobic polymeric housing offers considerable weight reduction and superior electrical performance.Designed especially for highly polluted areas, an insulator with a highly protected creepage polymeric housing has been developed. Its protected creepage design prevents both the deposition of contaminants and the complete wetting of the surface. Reduced leakage currents lead to a reduced flashover probability and therefore to significant energy savings. 

Advantages of Hybrid Insulators                                                                                                                      

The core is made by a simple extrusion process and this yields a low weight mechanical part with consistent mechanical properties as in any porcelain with sheds. The polymeric housing offers protection to this core as well as greater resistance to impact damage than the sheds in a conventional porcelain insulator. The hybrid insulator is typically half to one-quarter the weight of a conventional porcelain. This reduces transport costs, risk of damage during transport and installation and easier installation.
