Armoured -Un Armoured Cable

Armoured – Unarmoured Cables

An armoured cable is a cable with a metal protective covering to ensure electrical continuity of the safety ground. Armoured cables are used in applications where cables will be exposed to mechanical or environmental damage under normal operating conditions. These applications include power circuits in industrial plants, commercial buildings, processing plants and central and substation utility applications. An unarmoured cables are usually composed by a few or several sets of wires in each group at least two wires are twisted like a rope, each conductor are insulated and often around single central twist, outer is wrapped with highly insulating cover layer. The cable has the characteristics of internal electricity and external insulation. The unarmoured cable is easy to install and use.
