Product Description

Product Description

Characteristics of glass insulators

Glass is fully amorphous, it is a frozen liquid. This means it has no crystallographic structure responsible for ageing. Our unique manufacturing process makes glass even more reliable, stable and strong. We have decades of knowledge of this material, enabling us to provide our customers with unique benefits throughout the life cycle of their transmission line.

Fog Type Glass Insulator

The fog type profile is characterised by long and widely-spaced under-ribs, which prevent arc bridging between adjacent ribs. It is particularly effective in coastal areas (salt-fog environment) as well as in locally polluted areas where a higher specific leakage distance* is required.
