Composite Polymer Transmission Insulator (Long Rod Type)

Brouchers

From 66kV to 400kV we are manufacturing all types of Insulators, Tension/Suspension, and Post Insulators.
We are providing grading rings when system voltages are equivalent of greater than 220kV.
For 220kV Composite Polymer insulator the Grading Ring is provided at the energized end only and for 400kV Grading Rings are provided at both ends of Polymer Insulators.
