It is one of the subsidiaries of CRRC. History Predecessor Zhuzhou Electric Locomotive Works was founded in 1936. CRRC Zhuzhou Locomotive Co., .... History Two three-car Class 411 EMUs have been built by CRRC under a contract signed in June 2014. The railway announced in June 2019 that the units have had electrical problems, which the manufacturer refuses to fix under warranty. There have also been issues with procuring spare parts, as the costs of shipping the items from China exceed the value of the parts themselves The units were financed in part with a €25 million loan from the European Bank for Reconstruction & Development.

CRRC Zhuzhou Locomotive
CRRC Zhuzhou Locomotive Co., Ltd. is one of the electric locomotive manufacturers in China. It is one of the subsidiaries of CRRC. History Predecessor Zhuzhou Electric Locomotive Works was founded in 1936. CRRC Zhuzhou Locomotive Co., Ltd. On 31 August 2005, CSR Group Zhuzhou Electric Locomotive Co., Ltd. was spin-off from the locomotive works; the original legal entity of the locomotive works became an intermediate holding company for CSR Group only. After the formation of the listed company CSR Corporation Limited, the limited company "CSR Group Zhuzhou Electric Locomotive" became part of the listed portion of the group, and the intermediate holding company remained unlisted. The limited company also renamed to CSR Zhuzhou Electric Locomotive Co., Ltd.. In 2015 the company was renamed into CRRC Zhuzhou Locomotive Co., Ltd. ().

Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or trolley buses to collect power through contact with an overhead line. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. Other types of current collectors include the bow collector and the trolley pole. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad. The familiar diamond-shaped roller pantograph was devised and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
25 KV/50 Hz AC
Railway electrification systems using alternating current (AC) at are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60Hz), which simplifies traction substations. The development of 25kV AC electrification is closely connected with that of successfully using utility frequency. This electrification is ideal for railways that cover long distances or carry heavy traffic. After some experimentation before World War II in Hungary and in the Black Forest in Germany, it came into widespread use in the 1950s. One of the reasons it was not introduced earlier was the lack of suitable small and lightweight control and rectification equipment before the development of solid-state rectifiers and related technology. Another reason was the increased clearance required under bridges and in tunnels, which would have required major civil engineering in order to provide the increased clearance to live parts.

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, Electric multiple unit, electric multiple units, trolleybuses or trams. 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 (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. An overhead line consists of one or more wires (or Overhead conductor rail, rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a High voltage, high-voltage Electricity distribution, electrical grid. Overview Electric trains that collect their current from overhead lines use a de ...

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages. However, electrically powered single-unit railcars are also generally classed as EMUs. The vast majority of EMUs are passenger trains but versions also exist for carrying mail. EMUs are popular on intercity, commuter, and suburban rail networks around the world due to their fast acceleration and pollution-free operation, and are used on most rapid-transit systems. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting ...

Electric Multiple Units Of North Macedonia
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical c ...
