WebThe 2 × 25 kV autotransformer system is a split-phase electric power system which supplies 25 kV power to the trains, but transmits power at 50 kV to reduce energy losses. It should not be confused with the 50 kV system. In this system, the current is mainly carried between the overhead line and a feeder transmission line instead of the rail. http://www.ijsimm.com/Full_Papers/Fulltext2024/text20-2_561.pdf
WebThe overhead contact line inspection system commercialized by Hitachi High-Technologies Corporation can perform fast and accurate measurements of the wear, deviation, and height of the contact line, and can display the results in realtime.

An alternative type of overhead system – the Rigid Overhead Conductor-rail System (ROCS) – has a number of advantages over conventional tensioned overhead equipment (OHE) for application in specific station areas. A conventional OHE has a copper contact wire suspended from a catenary wire with the help of a dropper.

The generic term used by the International Union of Railways for the technology is overhead line. It is known variously as overhead catenary, overhead contact line … See more Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors … See more Catenary wires are kept in mechanical tension because the pantograph causes mechanical oscillations in the wire. The waves must travel faster than the train to avoid producing standing waves, which could break the wire. Tensioning the line makes waves travel … See more Given limited clearance such as in tunnels, the overhead wire may be replaced by a rigid overhead rail. An early example was in the tunnels of the Baltimore Belt Line, where a Π section bar (fabricated from three strips of iron and mounted on wood) was used, with the … See more To achieve good high-speed current collection, it is necessary to keep the contact wire geometry within defined limits. This is usually achieved by supporting the … See more In the Soviet Union the following types of wires/cables were used. For the contact wire, cold drawn solid copper was used to ensure good conductivity. The wire is not round but has grooves at the sides to allow the hangers to attach to it.
