In order to achieve high speed in Railways it’s important to keep the catenary wire in Railway, geometrically at the right position and that’s possible with the support of catenary wire. It’s strung between two points the catenary curves. The wire is connected to the catenary wire at regular intervals with the help of dropper wire. And this is supported regularly at structures. Catenary wire is loosely used than catenary wires to maintain the right height and position of the catenary wires. There can be three structural formation of catenary and they are simple, stitched and compound. For low speed vehicles like trams the catenary is suspended like a parabola due to its weight and the pantograph has space to move up and down, but this is not the case with high speed vehicle like in Railways. The entire electrification system is complex. The wire must be enabled to carry several thousand amps power and able to withstand in extreme winds and temperatures. The design of the structures of catenary positions now a day is usually designed by the computer. Catenary wire Railway, is placed horizontally. The transmission voltage is 600v DC which itself can kill a life and leave apart 25000 v AC that’s enough to fry a human life if touched the electrification. Catenary wire actually comprises of 19 strands of cadmium copper. Railway catenary wire manufacturer includes catenary system comprises of hangers, connectors, insulators, suspensions, tools and safety equipments, etc. catenary wire manufacturer in India usually produces other cables needed for Railway transportation System.
