Hello Everyone,
Cables are one of the important factors which plays important role in when it comes to in any railway signalling not only in indian railway.
Cable, in electrical and electronic systems, is a conductor or collection of conductors used to carry electric power or telecommunication signals from one location to another. Electric communication cables use electrical impulses to send voice messages, computer data, and visual pictures to telephones, wired radios, computers, teleprinters, facsimile machines, and televisions. There is no discernible difference between an electric wire and an electric cable. The former typically refers to a single, solid metallic conductor, with or without insulation, whereas the latter refers to a stranded conductor or a group of insulated conductors. Electrical signals are transformed to light pulses for transmission of audio, video, and computer data via fibre-optic cables, which are constructed of flexible glass and plastic fibres.
