A Solid Insulated VCB is a type of vacuum circuit breaker where the primary components, including the vacuum interrupter, are encapsulated in solid insulating materials. Unlike traditional VCB that rely on air or gas as the primary insulating medium, SIVCB use solid insulation, typically made from advanced polymeric materials. This design minimizes the need for maintenance and increases the longevity and safety of the equipment.
