Quick Details
Description
SF6-insulated ring main unit and SF6-insulated compact switchgear are used in medium voltage distribution networks. They offer a sealed stainless steel tank which contains all the live components and switching functions. The transformer is protected either by a switch fuse combination or a vacuum circuit breaker.
SF6-insulated ring main unit can be supplied as a 2, 3 or 4-way unit in standard configurations with additional equipment according to customer specification.
SF6-insulated compact switchgear has a unique flexibility due to its extendibility and the possible combination of fully modular and semi-modular configurations, with a maximum of 5 modules in one SF6-tank.
The units are delivered from the factory ready for installation. Routine tests are carried out on all units/ modules before dispatch. No special tools are required for installing the equipment.
