Pylon in mountains, power cables and glaicer in background
Photo showing a tall high-voltage transmission tower, which is known in the UK and much of Europe as an electricity pylon.  The photo shows a section of the tower, with wires, conductors and insulator strings.  This part of the structure is close to the top (peak) and known as the 'cage', with the 'crossarms' being visible.
