Free-Standing or Inside a Mini Compact Substation

As a free-standing unit, the ring main unit is placed directly at the site, which suits ring networks along roads, campuses and industrial estates. Inside a mini compact substation, it becomes part of a complete package with the transformer and low voltage side, which cuts down site work. For the complete package, see our substation product page.

Remote Monitoring Through SCADA

Because the unit is motorised and connects to SCADA through FRTU, operators can monitor and switch it from the control room. This saves travel to distant outdoor sites and keeps people away from live equipment during switching.

Outdoor and Indoor Ring Main Units: What Changes

Enclosure: an outdoor unit needs a weather-resistant enclosure, while an indoor unit relies on the building.
Placement: an outdoor unit stands free or sits inside a mini compact substation, while an indoor unit goes into a switch room.
Space: an outdoor installation does not need a separate switch room.
If your unit will sit inside a building, see our Indoor Ring Main Unit.
