D & A Systems have recently secured a contract at one of Europe’s largest manufacturing complexes at Airbus UK in Broughton. The prestigious project worth circa £1.5million will commence in 2013 and involve upgrading the site electrical infrastructure from 11kV upto 33kV.

The twelve month contract will involve the construction of a new Substation building and adjoining bunded compound which will accommodate two 20/25MVA ONAN / ONAF 33/11kV Distribution transformers affording Duobias ‘M’ transformer differential protection. In addition there will be a new Switchroom to house a fourteen Panel 11kV ABB UniGear ZS1 Switchboard c/w Micom P121 protection relays and SCADA system.

Operating under a separate contract, D&A Systems were employed to undertake the 33kV contestable connection for the project by Matrix Networks Ltd. This involved equipping a 33kV Primary substation which would later be adopted by ScottishPower following handover.
