Normally RMU's provide a few alternative combinations. Extension is available but often complicated and costly.

Smart Ring has the flexibility to create prefered combination between line or transformer feeders. It is possible to change from line to transformer feeder and vice versa after installation.

Smart Ring is provided in two basic versions a 3-bay and a 1-bay. From these basic versions most suitable combinations can be achieved. The switchgear is extendable in both directions also after installation. This reduces unnecessary investments for the utility and reduces the cost for replacement.

Operating mechnisms are exchangable after field installation.
