The Suez Canal overhead line crossing is an important electrical power line built across the Suez Canal in 1998. It is designed for 2 circuits of 500kV. Because the required clearance over the Suez Canal is 152 metres, the overhead line has two 221 meter high pylons on either side of the crossing, in spite of its small span width of 600 metres, The pylons each have 4 crossarms, 3 for the conductors and one for catching the conductors in case of an insulator string failure. http://en.wikipedia.org/wiki/Suez_Canal_overhead_line_crossing
