Тransmission system in the Republic of Serbia consists of overhead power lines, cables, substations and switching stations of 400 kV, 220 kV and 110 kV, except 110 /х kV substations which are part of the distribution system.

Transmission system is, on one hand, connected to production facilities, and on the other, to distribution system and customer facilities (industrial complexes and railway transformer stations). In addition, our transmission system is connected to all transmission systems in neighboring countries.

Мain purpose of the transmission system, along with the distribution system, is to enable reliable transmission of electricity from production facilities to end customers, as well as the international electricity exchange.

The tables below provide an overview of the transmission system’s capacity: the number and length of the overhead power lines, number and length of cables, number of switching stations and transformers with the installed transformation power.
