Electrical Contracting

Electrical design will take into account the level of resilience most appropriate to the requirement of your organisation. The switchgear for data centres can either be of the standard “off-the-shelf” type or be purpose made for a specific application. In either case it must be designed such that:

  • There are no single points of failure
  • Maintenance can be carried out safely without shutting down the IT load
  • There is capacity for future expansion which can be added without shutting down the IT load

With proper design, standard switchgear can be made to meet the above criteria however but it does have limitations. For example, on occasions it will be necessary to isolate a switchboard. With dual A & B supplies this does not necessitate shutting down the room but it does mean the room is on one supply for a time, and so is at risk.

Thamesgate can design and build switchgear purpose made for the particular application which allows us to meet other requirements, e.g. metering, bus-couplers, isolation transformers ‘Castell’ interlocks and so on, can be incorporated. Bespoke switchgear may appear more expensive initially, but over the life of a data centre it will pay for itself in lower maintenance costs, increased functionality and reduced risk.
