Transformer travels 5,500 miles to Willington villageContinue reading the main story
An electricity transformer the size of a house has been lowered into position in a south Derbyshire village.
The 255-tonne, 58m (190ft) long and 5m high (16ft) item forms the heart of a new substation at Willington.
Built in South Korea, it was taken by ship to Goole in East Yorkshire before being driven by a specialist haulage team to the site.
The trailer, flanked by police outriders, travelled at about 12mph along motorways and main roads.
The convoy travelled down the M1 and to junction 24 and then continued on to the A50.
It then left at junction three (the A514) before taking the A5132 and heading into the sub-station in Willington.
National Grid said it was installing the transformer at a weekend to minimise disruption.
James Berry from the National Grid said: "It is the size of a bungalow. To get it here meant a 5,500-mile journey.
"It came via a large container ship from Korea. It stopped off at Rotterdam, before completing the final bit of its journey into the UK.
"It's a very delicate piece of kit, so its delivery is a kind of military operation."
Project manager James Goode said: "The transformer is an important upgrade to the Willington sub-station.
"It means we can maintain the future supply of electricity to a large local area."
