How Railway Catenary Wire is made?

What is a Catenary Wire?

A catenary wire is generally used to transfer electrical power to all the trains. The rectification substations are responsible for powering the huge set of suspension cables. They change the industrial current arriving at the station into a suitable current for the RER (1,500 volts). This entire system allows easy and offsite control without the need for manpower to power a train.

Railway catenary wire manufacturers require a lot of experience to design manufacture and install them in the locations. The conductors which are made up of copper are made up of 19 wires each of diameter 3.20mm and have a very minimal area of cross-section of 150mm2. The conductor made up of Bronze is made up of 19 wires in total. In this only 2 wires are made of bronze while others are made up of material like Magnesium and Copper. Each wire has an area of cross-section 70mm2 and has a very less diameter of 2.1mm.

The catenary system supplies electricity to the trains having pantographs and can carry a safe load of a maximum of 340 kg with a safety factor of 5:1.

How to install Catenary Wires?

The Catenary Wires must be made and installed by high professionals. Search in Google to find the best manufacturer. Before hiring them, do check the ratings and go through their prior experience and qualifications. The installation process is a very dangerous task and has many risks. Also, it is an expensive process, so do compare the prices of different websites before stepping forward.

Many considerations should be taken into account such as electrical safety, positioning of wires, installation techniques, tools required to install them, and over everything, safety. So, before installing discuss with the best electrician to minimize these risks.

So, lastly, one suggestion chooses your manufacturer and electrician by doing a lot of research.

The Electrification for Hi Speed Travel "Contact Wire Railways“

Catenary wires are used to suspend contact wires using dropper wires in contact with pantograph. The railway overhead line system, thus provides electrification for hi speed urban transport system. Contact wire railways work as a conductor. With high thermal resistance, tensile strength it is highly reliable. And in India we have Victor cables are the manufacturers of contact wires here in India. Copper, Silver, Copper tin, Copper cadmium, Copper, magnesium is used as nomenclature to this wire. Contact wire railways are made into different types depending upon the traffic, high speed and normal criteria. It’s forecasted that by 2023 this domain is going to see a considerable jump in revenue. Globally, this figure reflects India can play a pivotal role in this segment being source or supplier according to the requirement classification. Railway contact wire manufacturer India’s accountability as major vendor will come up with the supply types of products or sub segments in this categ...

Railway Contact Wire Manufacturer

The Overhead Line Equipment includes the suspended wires over the railway lines to supply electricity. Among them, one important wire is a contact wire. It is the main component of the system providing electricity via the pantograph of the locomotive. The contact wire used in the railway is solid and hard-drawn grooved electrolytic. It could have a cross-sectional area of 107 sq. mm, 150 sq. mm, or 193 sq. mm. Basically, a high tensile strength combination of metals like Cu-Sn, Cu-Ag, and Cu-Mg is used for its manufacturing. Mostly a copper magnesium alloy is used for the same purpose. Choosing a good railway contact wire manufacturer depends on the availability, reliability, and durability of contact wires. All these criteria should be met before choosing the manufacturer. Also, the wires should be able to tolerate weather conditions like high rainfall, extreme temperatures, and pollution. They can be made to go through various tests to find the best railway contact wire manufa...
