The Railway Catenary system is a part of railway electrification. Railway overhead equipment is a big part. Today in this video, I am trying to explain OHE Equipment components and their function.
At the end of this lesson, you will learn the basics of the railway catenary system | Section Insulator(SI) | Auto Tension Devise.
A catenary wire, or a catenary system, is used in today’s modern running of electrically wired public transportation such as in trains.
The purpose of implementing this system when constructing new train stations and lines or adding new trains or trams to an existing line is to provide power. All systems are controlled from a feeder station and are powered by and managed remotely. The system allows for easy, offsite regulation without needing to physically power a vehicle from the localised source within the machine itself.
Unlike uninsulated wires attached to crosswires by clamps, a catenary system uses two wires – a catenary wire and a contact wire. The catenary wire is hung between line structures at specific tension and a contact wire is attached to it at a frequent interval by droppers. This second wire is straight, parallel to the railway track and integral to the catenary system’s structure.
Catenary wire material is made up of tiny threads which feed electricity through to a vehicle from the pantograph which presses against the underside of the lowest overhead wire- contact wire.
