Voltshield for ceramic and glass insulators

The VoltShield System has been specially developed for the renovation, protection and maintenance of
glazed ceramic and glass electrical insulators.

VoltShield prevents pollution build-up on the surface of electrical insulators for:
- Increased electrical performance
- Reduced corona activity
- Reduced flashover failures
- Potentially increased insulator service life

Glass and ceramic surfaces are chemically reactive and reveal a rough surface with many potholes when looked at under a microscope. When left unprotected, those surfaces quickly and easily suffer permanent bonding of organic and inorganic air- and water-borne contaminants such as limescale from cement-dust, mortar concrete, brickwork and stonework run-off, mineral salts from seawater, unburned hydrocarbons from industrial and traffic pollution, and metal oxides. These contaminants deposit in the potholes and react chemically, bonding firmly to the surface.

Voltshield is a chemically cross-linking polymeric resin with incredible 'non-stick' properties. Its application provides a highly mobile surface to disperse and minimise water aggregation.
