Medium voltage gas-insulated ring main unit for secondary distribution, 12 kV, 630A
SafeRing Air is a ring main unit (RMU) for the secondary distribution network. The SafeRing Air portfolio is based on dry air technology as insulation medium. The switchgear design is based on the existing SafeRing portfolio, offering an advantage to the end users with the same user interface, footprint, spare parts and operation.

SafeRing Air can be supplied in 18 different standard configurations suitable for most switching applications in 12 kV distribution networks.

SafeRing Air is a completely sealed system with a stainless steel tank containing all 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.
