The Role of Glass in Power Line Insulators

Electrical insulation and mechanical support

Glass insulators help support conductors and provide electrical insulation between energized parts and supporting structures. The glass shell is an insulating component of the assembly, working together with metal fittings.

Glass is used for its electrical insulating properties, mechanical strength and durability. Insulator performance also depends on the unit design and the operating environment.

Applications

Applications include overhead power lines and related electrical infrastructure. The required design varies with the mechanical and electrical duties of the installation.
