Insulating gas Decomposition abb

Insulating gas Decomposition abb

Gas-insulated switchgear (GIS) has solved many problems by providing a far safer and more compact solution. The only significant drawback has been the use of SF6 gas, which requires very careful handling to avoid environmental issues. That drawback has been greatly reduced with AirPlus gas, now available in ABB GIS.

    The fibers can be laid at any angle from 10& to 90& to the longitudinal axis. An inner layer of polyester liner is normally used. This is a requirement for insulators used for gas-insulated circuit breaker applications to withstand decomposition products of the insulation gas SF6. Precise and defined winding of the fiber onto the mandrel

    The combined disconnect/earth switch (D/E) for the gas-insulated switchgear (GIS) type ELK-03 was introduced in 1987 and later has been used for the GIS type ELK-04 as well. This design is based on one common switch blade in rotating movement driven by one common operating DC-motor for both disconnect and earth switch.
