Abnormal loads specialist Collett & Sons has had a busy couple of weekends moving heavy transformers for the energy sector. The company delivered the first 178-tonne transformer from Tilbury Dock to Biggleswade Substation. It was the first of two such supergrid transformers the company delivered for its compatriot grip operator, National Grid. 

The two large supergrid transformers at the new Biggleswade substation in Dunton will provide a new connection for UK Power Networks, that will increase power capacity in Biggleswade and help the community move towards a low carbon economy.

To transport the first unit on February 11, Collett loaded the transformer onto a 20-axle girder bridge configuration. The truck and trailer combination had a total vehicle length of 66.1 metres.

Upon arrival at the site, the transformer was skidded directly from the trailer onto the final plinth. The second transformer followed the same path on February 18.

The convoy route took it from Tilbury via the M11, leaving at junction 10 west towards Royston continuing up the A1198 and then the B1042 on its way to Dunton.

The route has been carefully planned in collaboration with highway authorities and the police to minimise disruption and those directly affected have been informed.
