Ground wires or earth wires are bare conductors supported at the top of transmission towers. They serve to shield the line and intercept lightning stroke before it hits the current carrying conductors below i.e. power lines. Ground wires normally do not carry current.
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, 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 … 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 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 … See more Lines are divided into sections to limit the scope of an outage and to allow maintenance. Section break To allow maintenance to the overhead line without having to turn off the entire system, the line is … See more Trams draw their power from a single overhead wire at about 500 to 750 V. Trolleybuses draw from two overhead wires at a similar … 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 contact wire from a second wire known as the messenger wire (in the US & Canada) or … 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 WebWe have manufactured material Handling systems as per Clients requirements such as...EOT Cranes, Semi-EOT Cranes, Hot Cranes, wire rope electric hoist, Chain Type Electric Hoist, Chain Pulley Brick, Pillar and wall mounted Jib Cranes (Electrically as well as Manually Operated) Goliath Cranes(EOT / Semi-EOT as well as manually operated) Cage Hoist, …
