Story: Engineering on the sea floor
In 1991, three new power cables and two new fibre-optic cables were laid along the Cook Strait sea floor. The new power cables are 126 millimetres in diameter, very heavy (1 metre weighs 52 kilograms), and can carry 350 kV 1,430 amps of high-voltage direct current. Watch footage of the Skagerrak laying them.
