Gas Insulated Breaker (GIB)

A Gas Insulated Breaker (GIB) is a type of high-voltage circuit breaker that uses sulfur hexafluoride (SF₆) gas as an insulating and arc-quenching medium. It is a key component of Gas Insulated Substations (GIS) and is widely used in urban or space-constrained environments due to its compact size and reliability.

Compact Design: Ideal for installations with limited space, such as urban or industrial areas.

High Reliability: Sealed construction minimizes exposure to environmental factors, reducing maintenance.

Arc Quenching: SF₆ gas effectively extinguishes electrical arcs during switching operations.

Insulation: SF₆ provides excellent dielectric properties, allowing for smaller clearances between live parts.
