Wires for Overhead Electrification Systems

An overhead wire utilized to carry electrical vitality to cable cars, trolleybuses or trains collectively defined as contact wire system. On the other hand catenary wire are basically cords of uniform density across a specific cross-section that is perfectly flexible, but not capable of being stretched and therefore hangs. To keep the high-speed current flowing for the efficient functioning of trains, trams and metros it's mandatory that the contact and catenary wire's geometry is within the desirable limits.

Difference between the two wires

Catenary wires: With these wires, the supply of electricity is done through an overhead system of suspended cable that keeps on hanging.

Contact wires actually carry the electricity. They are hung from or are connected to other wires which assure that the contact cable is at an equal height and in the correct position.

The contact and catenary wire is basically our present as well as our future demand and so accordingly managing with the present scenario of development, such wire is manufactured for the better functioning of trains, trams, cord cables and metros.

Catenary wires, however, are facing major challenges these days because of their composition which is basically a combination of Copper and Cadmium. Here, Cadmium is highly toxic, so several implementation techniques are undertaken to replace the Copper - Cadmium combination with a Copper - Magnesium combination which is by far much suitable than the previous combination.

So we can basically conclude that by including that the two wire configurations helps maintain a constant height for systems like trains, trams, metros and cord cables.
