Features of Silicone Rubber Insulator
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
