How it Works

The problem: why does pollution build up?

Glass and ceramic surfaces are chemically reactive and reveal a rough surface with many potholes when looked 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.

How does VoltShield™ provide the solution?

VoltShield™ is a chemically cross-linking polymeric resin with incredible ‘non-stick’ properties. This surface permits the rapid dispersal of water and does not allow adherence of solid pollutant due to its cross-linked molecular bonding. This results in enhanced electrical performance and reducing both corona activity and flashover failures.

Power frequency withstand and flashover voltage independent tests conducted on VoltShield™ treated insulators to IEC 60060 by HVL Tamworth High Voltage Laboratory, UK, have shown a marked increase in the wet withstand and flashover voltage values compared to similar untreated insulators.

VoltShield™ is a transparent treatment that will not mask the original glazed color and identification mark of the insulator. It can be applied onto new or existing insulators in the factory or on-site.

How long does it last?

The protection is hard-wearing and durable because when cured VoltShield™ chemically bonds to the surface of the insulator creating a strong ‘non-stick’, low-maintenance barrier.

The VoltShield™ protection is expected to last for up to 10 years depending on maintenance and conditions of use.

Because VoltShield™ is not a coating, it will never crack, discolor or peel off during handling and when exposed to weathering.
