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.
