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 accord

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
