Power plant telecommunications from 1988

Electric power facilities are often located away from the usual telecommunication lines. Therefore, transmission lines are the only option for a reliable and economic connection. This is the reason for establishing the first high-frequency connections through transmission lines as early as 1920.

Their use has been growing very fast, until the optical cable became a constituent part of the transmission line. Optical cables successfully replace high-frequency connections due to their extraordinary telecommunication capacities. The high-frequency connections remain mostly on older transmission lines without optical cables, on long transmission lines and in places where a high reliability rate is required. The ELES Company has integrated 1,612 km of optical cables so far.
