Sweden's Roxtec has been selected as a preferred safety seal supplier by contractor Engie Fabricom, following the deliveries for the substation at Dong Energy's 258MW Burbo Bank Extension offshore wind farm off the UK. The supplier's transits have been used on the platform to seal off hundreds of high voltage power cables, signal and fiber optic lines, and a wide range of pipe penetrations on everything from air-conditioning to fire-fighting systems.
