keskijännitteeksi

Keskijännitteeksi, meaning "medium voltage" in Finnish, refers to a range of electrical voltages typically used in power distribution systems. It bridges the gap between low voltage, commonly found in residential and commercial buildings, and high voltage, used for long-distance transmission. The specific voltage levels classified as keskijännitteeksi can vary slightly depending on regional standards and applications. Generally, it encompasses voltages from approximately 1 kilovolt (kV) up to around 35-72.5 kV.

This voltage class is crucial for efficiently distributing electricity from substations to various end-users, including industrial facilities, larger commercial complexes, and sometimes even groups of smaller residential areas. Keskijännitteeksi allows for more economical transmission of power over moderate distances compared to low voltage, as it requires smaller conductors and results in lower energy losses. However, it still necessitates a certain level of insulation and safety precautions due to its higher potential compared to household electricity. Transformers are essential components in keskijännite systems, stepping down the voltage to safe and usable levels for final consumption.
