Ring Main Unit

Other Details
ABB offers a complete solution for 12/24 kV distribution networks. This consists of Safe Ring, a Ring Main Unit (RMU) that can be supplied in various configurations and Safe Plus, a compact switch gear with unique flexibility. Safe Plus offers extendible and fully / semi modular configuration possibilities. Both the units have identical user interfaces. Safe Ring / Safe Plus are delivered as a completely sealed system with a stainless steel tank containing all the live parts and the switching equipment. Constant atmospheric conditions in the sealed tank ensures a high level of reliability, safety and a virtually maintenance-free system. As an option in Safe Plus, an external busbar can be provided to enable a completely modular configuration. Safe Ring and Safe Plus can also be fitted with a remote control and monitoring unit and are suitable for both indoor and outdoor applications.
