Features
- Light weight (65-80% less than ceramic insulator)
- Silicon rubber sheds provide perfect hydrophobic performance, good resistance to ageing,
tracking and erosion
- Stable behaviour at extreme climatic conditions
- Long term surface hydrophobicity
- Suitable for polluted environment, salty atmospheres etc.
- Resistance to breakage and vandalism, practically unbreakable
- Superior anti-tracking properties
- High mechanical strength
- Ease of installation (easier handling with lighter equipment and labour at the job site)
- Resistance to Seismic Shock
- Compliance with IEC 61109, ANS C29-11-1989
