Keskijänniteverkosto

Keskijänniteverkosto refers to the medium voltage electricity distribution network used in Finland. It operates at voltage levels typically between 1 kilovolt and 36 kilovolts, bridging the gap between the high-voltage transmission network and the low-voltage distribution network that supplies electricity directly to consumers. The primary purpose of the keskijänniteverkosto is to efficiently transport electrical power over moderate distances from substations, where voltage is stepped down from the transmission level, to local distribution points.

These networks are essential for supplying electricity to industrial areas, commercial centers, and residential neighborhoods that are not within immediate proximity of the high-voltage lines. The infrastructure of a keskijänniteverkosto typically consists of overhead power lines supported by poles or underground cables. These lines are designed to carry larger amounts of power than low-voltage lines but require less complex and costly construction than high-voltage transmission systems.

The management and maintenance of the keskijänniteverkosto are the responsibility of regional electricity distribution companies. These companies ensure the reliability and safety of the network through regular inspections, repairs, and upgrades. The design and operation of these medium voltage networks are crucial for the stable and continuous supply of electricity to a wide range of end-users across Finland.
