Do you know what is Catenary Wire and how it works - Kebles Trading

Описание: 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.

Electrical current is then allowed to flow through to the train and back to the feeder station through the steel wheels on the running rails. As high voltages of electricity is transmitted throughout the running of the train or tram, a catenary system uses many large insulators to keep it physically and electrically isolated to just within the system.

Catenary wire fixings come in many different types and in various forms. The fixings affix to the wire to connect the entire system and secure it while also allowing electrical current to run through with ease.

For more information on the types of fixings best suited to the wire you need, give us a call today to discuss your options.
Installing a catenary system is an intricate process that should be handled only by a professional electrician.

Not only can catenary wire installation be dangerous with many associated risks, it’s also a very involved task that shouldn’t be taken by someone who doesn’t have a current electrical license and is not well-equipped.

Catenary prices can vary depending on the type of wire used as well as the required amount of length needed. Give us a call to discuss your project and budget and we will be able to give you a tailored quote.
