What range of voltage do distribution lines typically operate at?

Distribution lines typically operate in the range between 2.4kV and 23kV. This voltage range is designed to effectively deliver electrical power from substations to end users, such as residential, commercial, and industrial customers. The typical voltages within this range allow for efficient transmission while minimizing energy losses and ensuring safety.

Distribution lines are intended to distribute electricity over shorter distances than transmission lines, which operate at higher voltages to cover long distances efficiently. By operating within the specified range, distribution systems maintain a balance between safety, efficiency, and infrastructure costs.

Using voltages above this range, such as those in the 24kV to 69kV range, is typically reserved for sub-transmission lines, which serve to feed power to multiple substations and are not considered part of the typical distribution system serving individual customers directly. Thus, the 2.4kV to 23kV range is characteristic of standard distribution lines.
