The 10 kV Power Supply System

The 10 kV system runs in Norðoyggum, Tórshavn, Sandoy and Suðuroy. This stems back to the old days, before SEV reached across the whole country.
In the transformer substations the voltage is altered from 10 kV to 0.4 kV, which is then used by households and companies.
SEV has 16 10/0.4 kV transformer substations, 165 kilometres of 10 kV lines, 151 kilometres of 10 kV cables, and 7.2 kilometres of 10 kV sea cables.
