Polymeric Standoff Insulators/ Support Insulators
Polymeric Insulator (Support Insulator) consists of a
fiberglass core covered with weather resistance polymeric
shedded sleeve and aluminium end fittings. These insulators
offer significant advantage like better performance in highly
polluted environment, flame / arc resistance, resistance to
chemicals and UV rays and are Vandal proof.
-
Specally designed polymeric material used in these
insulators have a self cleaning property.
-
Surface hydrophobicity is maintained over a long period.
-
Unbreakable, compact and light weight compared to
porcelain insulators.
- Metal end fitting as per customers requirement.
