The 400 V Power Supply System

When the voltage has been changed to 400 V the electricity is distributed, mostly via cable, to customers on the 400 V power supply system. The link between SEV and its customers are the grey electricity distribution lockers, which are placed along the roads. The cable going into the house is the customer’s property.
 
SEV has 5570 distribution lockers around the country and 652 kilometres of 400 V cables.
