Composite Polymer Insulators (Long Rod Type)
Composite Polymer Insulators (Long Rod Type)
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.
Our Products Range
66kV Composite Polymer Long Rod Insulators
132kV Composite Polymer Long Rod Insulators
220-400 kV Composite Polymer Long Rod Insulators
