mellemspænding

Mellemspænding refers to a range of alternating current (AC) electrical voltage levels that fall between low voltage and high voltage. In the context of electrical power distribution, it is the voltage used for transmitting electricity from substations to local distribution networks. The specific voltage range considered "mellemspænding" can vary by region and country, but it generally lies between 1 kilovolt (kV) and 36 kV. This voltage level is chosen because it offers a practical balance between the efficiency of transmitting electricity over longer distances and the safety and manageability of the equipment used at this level. Mellemspænding lines are typically carried on overhead poles or underground cables and are a critical part of the infrastructure that brings electricity to homes, businesses, and industries. Substations then step down the mellemspænding to lower voltages, such as 230V or 400V, for direct use by consumers. The transition from high voltage transmission to lower voltage distribution involves a series of transformer stations, with mellemspænding being an intermediate stage in this process.
