Lillebælt (Little Belt) 420 kV AC cable system comprising two parallel 13 km circuits between Jutland and Funen, including 7.5 km of three-core submarine cable in the Lillebælt strait and 5.5 km of underground land cable.
Energinet.dk awarded ABB a turnkey contract for the Lillebælt (Little Belt) 420 kV cable project to replace two 400 kV overhead line crossings between Jutland and Funen with underground and submarine cables. In February 2012 ABB received the order to design, manufacture and install the complete 420 kV AC cable system, including about 15 km of three-core submarine cable laid as two parallel circuits across the Little Belt strait and approximately 30 km of single-core underground land cables forming the onshore sections. ABB’s scope covered system and cable design, production at its Karlskrona high-voltage cable factory, supply of all submarine and land cables, accessories and terminations, and execution of marine and land installation including sea cable laying and commissioning tests before handover to Energinet.dk in late 2013.
