154 kV Vaniköy-Etiler
The Bosporus overhead line crossing 1 was the first overhead transmission line crossing the Bosporus. It was inaugurated in 1957 and it is designed and operated for two 154 kV circuits. Although apparently designed for overhead ground wires, none are currently present.The span width is 1782 m (5,846.5 ft), clearance over Bosporus is 59 m (193.6 ft).
380 kV Anadolukavağı-Rumelikavağı
Bosporus overhead line crossing 2 is the second transmission line across Bosporus. It is designed for two 420 kV circuits and it went in service in 1983. It has a span width of 1906 m (6,253.3 ft).Bosporus overhead line crossing 3 is the third overhead line crossing of the Bosporus. It is adjacent to the second crossing, and is designed for four 420 kV circuits, but can be used after some re-engineering work also for 800 kV lines. Since 1999, two of the four circuits are in use.
