Advantages of sf6 Service

The use of solid dielectric for busbar systems, instead of SF 6, has the advantage that it enables the SF 6-based units to require no gas handling onsite during installation, commissioning and operation of the GIS equipment. Another advantage with the use of other alternatives is less impact on the environment and on the material used for the electrical insulation.
