Part of a distribution network
A ring main unit provides switching functions at a connection within a distribution network. Its role is understood together with the incoming supply, outgoing feeders and transformer connection.
Why compact construction matters
Urban developments and building substations place strong demands on footprint, access and maintenance. Compact switchgear can be combined with suitable transformer and measurement equipment to meet these requirements.
Selection by network duty
The choice between load-switch and circuit-breaker protection depends on the network and transformer protection requirements. Reliability, operating arrangements and lifecycle maintenance are central considerations.
