keskijännitteelle

Keskijännite refers to a medium voltage level within an electrical power distribution system. This voltage range typically falls between low voltage, which is used for direct customer connections, and high voltage, which is used for long-distance transmission. In many electrical grids, keskijännite serves as the crucial link between substations that step down transmission voltages and the lower voltage lines that supply homes and businesses.

The specific voltage range designated as keskijännite can vary by region and country, but it commonly spans from approximately 1,000 volts (1 kV) up to around 35,000 to 70,000 volts (35-70 kV). This intermediate voltage allows for efficient power delivery over moderate distances without the significant losses associated with very low voltages or the complex infrastructure required for very high voltages.

Keskijännite lines are often carried on poles or routed underground. They are tapped by distribution transformers, which further reduce the voltage to the levels suitable for end-users. These lines are managed by utility companies and are a vital part of the infrastructure that ensures a reliable supply of electricity to various sectors, including residential, commercial, and industrial consumers. Safety measures and specialized equipment are employed to manage and maintain these keskijännite networks.
