Overhead line crossings of the Little Belt
Two parallel 380 kV three-phase power lines run across the Little Belt near Middelfart in Denmark . Both lines cross the Little Belt on delta masts . The masts of the overhead line crossings over the Little Belt are visible from afar and after the masts of the Limfjord overhead line crossing 2 belong to the highest overhead line masts in Denmark.
Line 1
The masts of line 1 are at 55 ° 31 '36 " N , 9 ° 41' 29" E on mainland Denmark and at 55 ° 31 '6 " N , 9 ° 41' 31" E on Funen. The 113.1 meter high mast on the Danish mainland carries a directional radio station, the mast on Fyn is 119.5 meters high.
Line 2
The masts of line 2 are at 55 ° 31 '36 " N , 9 ° 41' 26" E on mainland Denmark and at 55 ° 31 '6 " N , 9 ° 41' 27" E on Funen. The mast on mainland Denmark is 119.2 meters high and the mast on Funen is 125.3 meters high.
Replacement of overhead lines with three-phase cables
ABB received the order to supply and install this cable system in February 2012 from the Danish transmission system operator Energinet.dk. The system consists of a total of 30 km of 420 kV single-conductor land cables and a total of 15 km of the 420 kV three-conductor cable. Due to the power to be transmitted, two three-phase systems are laid in parallel, each of which can transmit 500 MW . When the project is completed in autumn 2013, it will be the world's most powerful three-wire AC submarine cable system.
