Post Insulator 11 kv & 22 kv

We offer Post insulators that have a metal bolt down base as opposed to threads. Many early multipart lines are spotted with line post insulators as replacements. Post insulators are also used in substations to insulate high voltage switching gear and transformers. These can be custom-made according to client's requirements.

Disc Insulator ( B & S Insulator, T & C Type)

Our range of Disc Insulators (B & S Insulator, T & C Type) with electro mechanical strength are provided with reasonable power frequency. These insulators can withstand voltage and power frequency of puncture voltage that ensures stable functioning. The glaze applied is compressive in nature, adds to mechanical strength and provides smooth surface for self-cleaning under contamination. We also design these insulators as per client's requirements.
