WAG-7
The Indian locomotive class WAG-7 is a class of 25 kV AC electric locomotives that was developed in 1990 by Chittaranjan Locomotive Works for Indian Railways. The model name stands for broad gauge (W), alternating current (A), goods traffic (G) engine, 7th generation (7). They entered service in 1992. A total of 1970 WAG-7 were built at CLW and BHEL between 1990 and 2015, which made them the most numerous class of mainline electric locomotive till its successor the WAG-9. The WAG-7 is one of the most successful locomotives of Indian Railways currently serving both freight and passenger trains for over 30 years. Even though with the advent of new 3-phase locomotives like WAG-9 and WAG-12, all WAG-7 locomotives except ones destroyed in accidents, rest are in service and doing all types of duties. History The history of WAG-7 begins in the early 1990s with the aim of addressing the shortcomings of the previous WAG-5 class and remove steam locomotives from IR by a target date ...

Electric Loco Shed, Asansol
Electric Loco Shed, Asansol is a motive power depot performing locomotive maintenance and repair facility for electric locomotives of the Indian Railways, located at Asansol of the Eastern Railway zone in West Bengal, India. It is one of the two electric locomotive sheds of the Eastern Railway, the others being at Howrah (HWH). As of November,2022, there are 142 locomotives in the shed. History Steam locomotive sheds used to exist at Asansol (Howrah) until the late 1970s. After Eastern Railway set a deadline to eliminate all steam locomotive operations by 1990, a push was given towards establishing electric locomotion as the primary motive power, and the Steam locomotive sheds was decommissioned.

Indian Locomotive Class WAG-8
The Indian locomotive class WAG-8 is a class of 25 kV AC electric locomotives that was developed in the early 1990s by Bharat Heavy Electricals Limited (BHEL) for Indian Railways. The model name stands for broad gauge (W), AC current (A), freight/goods traffic (G), eighth-generation (8). Only two units of this class were built, both prototypes. This class provided the basic design for a number of other locomotives like the WCAM-2, the WCAM-3 and the WCAG-1. History The history of WAG-8 begins in the early 1990s with the aim of addressing the shortcomings of the previous WAG-5 class and remove steam locomotives from IR by a target date of 1990. The WAG-5 though were greatly successes, had become underpowered to meet the growing demands of the Indian Railways. So in the early 1990s BHEL decided to look for a successor to the WAG-5 class. The required specification was of a 5000 horsepower locomotive. Initially, the Indian railways invited tenders to build locomotives to t ...

Bharat Heavy Electricals Limited
Bharat Heavy Electricals Limited (BHEL) is an Indian central public sector undertaking. It is under the ownership of Ministry of Heavy Industries, Government of India. It is based in New Delhi, India. Established in 1956, BHEL is India's largest government owned power generation equipment manufacturer. History BHEL was established in 1956 ushering in the heavy electrical equipment industry in India. Heavy Electricals (India) Limited was merged with BHEL in 1974. When it was set up in 1956, BHEL was envisaged as a plain manufacturing PSU, with technological help from the Soviet Union. In 1980's it was cutting edge in thyristor technology. In 1991, BHEL was converted into a public company. Over time, it developed the capability to produce a variety of electrical, electronic, and mechanical equipment for various sectors, including transmission, transportation, oil and gas, and other allied industries.

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview 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 ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thyristor
A thyristor () is a solid-state semiconductor device with four layers of alternating P- and N-type materials used for high-power applications. It acts exclusively as a bistable switch (or a latch), conducting when the gate receives a current trigger, and continuing to conduct until the voltage across the device is reversed biased, or until the voltage is removed (by some other means). There are two designs, differing in what triggers the conducting state. In a three-lead thyristor, a small current on its Gate lead controls the larger current of the Anode to Cathode path. In a two-lead thyristor, conduction begins when the potential difference between the Anode and Cathode themselves is sufficiently large (breakdown voltage). Some sources define silicon-controlled rectifier (SCR) and thyristor as synonymous. Other sources define thyristors as more complex devices that incorporate at least four layers of alternating N-type and P-type substrate. The first thyristor devices were ...
