Introduction of Composite polymer Insulators
Yamuna Power & Infrastructure produces Composite silicone rubber Insulators confirming to International Specifications and standards. In the early days, insulators were made of ceramic and glass material only. But in late 1960's polymeric insulator were developed and its improvements in design and manufacturing in the recent years have made them attractive to utilities.

The usage of composite insulators demonstrating their capabilities in diverse environment and now the usage is growing to prevent line flash over triggered by pollution.
With advanced technology, superior & reliable equipment and strict quality control our company comes out as one of a quality manufacturer for composite silicone rubber
insulators. The composite silicone rubber insulators offer significant benefits such as better contamination performance, lighter weight, and seismic resistance.

Technology Advantages of Composite Silicone Insulator

- Light weight (25-30% less than ceramic insulator)
- Silicone rubber sheds provides perfect hydrophobic performance, Good resistance to aging, tracking and erosion.
- Stable behavior at extreme climate conditions.
- Long term surface hydrophobicity.
- Suitability for polluted environment, salty atmospheres etc.
- Resistance to breakage and vandalism, Practically unbreakable.
- Superior anti-tracking properties.
- High mechnical strength.
- Ease of installation (easier handling with lighter equipment and labor at the job site)
- Resistance to Seismic Shock
- Compliance with IEC 61109, ANSI C29-11-1989
