In our world, a catenary is a system of overhead wires used to supply electricity to a locomotive, streetcar, or light rail vehicle which is equipped with a pantograph.
What is the difference between the catenary and contact wire?
Catenary wires are used to hold the contact wire in a straight line. Contact wires are used to transmit power to a pantograph of a locomotive. Part of OHE line which is used for interconnections.
What is catenary in electric traction?
A catenary is a system of overhead wires used to supply electricity to a locomotive, tram (streetcar), or light rail vehicle that is equipped with a pantograph.
Does catenary wire carry current?
This catenary wire (also called a messenger wire) has closely spaced “drops,” which support the actual contact, current-carrying wire. The return path for the current is the track rail, which is at ground potential and thus not electrically dangerous. Further, the catenary wire must remain properly taut and tensioned.
Which wire is used in railway?
The catenary wire is made of copper or copper alloys of 70, 120 or 150 mm2. The smaller cross sections are made of 19 strands, whereas the bigger has 37 strands. Two standard configurations for main lines consist of two contact wires of 100 mm2 and one or two catenary wires of 120 mm2, totaling 320 or 440 mm2.
What is a catenary support?
In our world, a catenary is a system of overhead wires used to supply electricity to a locomotive, streetcar, or light rail vehicle which is equipped with a pantograph. The pantagraph presses against the underside of the lowest overhead wire, the contact wire.
