Distribution Switchboards

Distribution Switchboards are used as the main electrical power distribution points in a building or process plant. They can range in size from a small panel fed from a pole mounted transformer using a 100A incomer, to a complex system with multiple Air Circuit Breaker incomers.

Rolla are able to provide transformer enclosures, including all connections between the transformer and the switchboard (package sub). We can supply enclosures for transformers up to 3.5MVA together with switchboards incorporating multiple incomers and buscouplers up to 6300A individual rating.

Some data centres require double rated neutral bars due to the harmonics on the network.

Our form of supply is the enclosure and integrated busbar system, plus we will fit any free-issue switches as required. All switches fitted by ourselves will be connected to the busbars with solid copper links to ensure the highest possible integrity. Our customers then fit the metering, controls and wiring to form the finished board.

This is just a selection of recent jobs completed, for a wide range of end users and industry applications. See our news page for more examples.

We fit a range of free-issue switches from major manufacturers including Socomec, ABB, Merlin Gerin etc. as can be seen above.

IP ratings are from IP54 down to IP2X as required. We can also supply Infra-Red monitoring facilities to enable live inspections on a routine basis.
