Custom geometries solutions for public transportation industry
Public transportation such as commuter and rapid transit trains, trams, and busses may derive primary power from a high voltage AC (up to 25kV/60Hz) or DC (600-1500VDC) power line in the form of an overhead line or a third rail. High Voltage AC line power is first stepped down and rectified to produce DC. Power from a high voltage DC link is then converted to 3-phase AC power for powering traction motors and auxiliary AC power for powering equipment such as air-conditioning compressors or fans.

Power Lines
Different types of power lines serve to transport electricity from the generation site to the end-users. Most commonly, and for efficiency reasons, the electricity is transported over long distances as alternating current at 50 or 60 Hz, carried overhead or underground using high voltage power lines or cables. Over very long distances or underwater, transmission occurs sometimes with high voltage direct current (HVDC). Power lines transmitting alternating current (AC) are surrounded by low frequency electric and ...
