Electrical Cables are used to connect two or more devices with each other which enable them to transfer of electrical signals or power from single device to several other devices. Cable assemblies are used for a variety of purposes, and each one must be custom-made for that specific purpose. Long distance communication is carried out over undersea cables. Power cable assemblies are used for bulk of data transmission for alternating and direct current, especially using high voltage cable. Electrical cables are widely used during building wiring for lighting, control circuits and power permanently installed within the buildings. Since the circuit conductors required can be installed in a cable at the same time, installation labor is saved in cable assemblies compared to custom wiring methods.

Cable Assembly Modern ApplicationsActually, cable assembly consists of one or more conductors with their own internal insulations with optional screens, assembly protection, individual coverings and protective coverings. Electrical cables can be made more malleable by stranding the wires. During this process, smaller individual wires are braided or twisted together to produce longer wires that are more malleable than other solid wires of same size. Clustering together small wires before concentric stranding adds more flexibility. Copper wire assembly may be bare, or they can be plated with a tinny layer of other metal, most often tin but sometimes silver, gold or some other material. Gold, tin and silver are less prone to oxidation reaction than copper, which may increase wire life, and makes soldering of wire easier. Tinning method is also used to provide lubrication among each strand.
