Composite Polymeric Insulator - 33 Kv

These Composite Polymeric Insulator - 33 KV made of glass and porcelain (ceramic insulators) used in power transmission and distribution systems ruled the market till the introduction of polymeric insulators which have potential to replace the ceramic insulators because of lightweight, aesthetic, hydrophobic properties, and superior anti-contamination performance and being a non-polluting industry it also helps prevent Global Warming.
A typical modern composite line insulator consists of a glass fiber reinforced resin (GFR) bonded rod (FRP) onto which two-metal end fittings are attached at both the ends. This FRP Rod with metal end fittings will carry the load of the conductor and is fixed to the supporting structure. To improve its resistance to environmental stresses, it is covered with the polymeric rubber, called Housing. The Silicone rubber is the most suitable and established material for all environmental conditions used now in Housing.
