UN-GM6 is a SF6-insulated ring main unit for the secondary distribution network. UN-GM6 can be supplied in 10 different configurations suitable for most switching applications in 12/24/36 kV distribution networks. As an option, UN-GM6 can be delivered as extendable ring main unit.
Together, UN-GM6 represent a complete solution for 12/24/36 kV secondary distribution networks. UN-GM6 have identical user interfaces.
UN-GM6 is a completely sealed system with a stainless-steel tank containing all the live parts and switching functions. A sealed steel tank with constant atmospheric conditions ensures a high level of reliability as well as personnel safety and a virtually maintenance-free system.
The UN-GM6 concept offers a choice of either a switch fuse combination or circuit breaker with relay for protection of the transformer. UN-GM6 can be supplied with an integrated remote control and monitoring unit.
UN-GM6 is a SF6-insulated, extendable compact switchgear system for secondary distribution. The switchgear has a unique flexibility due to its extendability and the possible combination of fully modular and semi modular configurations.
UN-GM6 also has non-extendable cabinet, which save cost on external busbar and smaller size.
