3.5 CORE ALUMINIUM XLPE ARMOURED POWER CABLES

An Armoured Cable is a type of cable covered in a metal sheath. Armoured cable is a cable with a metal protective covering to ensure electrical continuity of the safety ground. It is used to conduct power. Armoured cables are used in applications where cables will be exposed to mechanical or environmental damage under normal operating conditions. This cable constitutes the best cable for transmission & distribution lines because of its excellent electrical and physical properties. The mutual capacitance of XLPE cables is also lower, thus reducing the charging currents & earth-leakage currents in networks without the rigid star-point earthing. The excellent resistance to thermal deformation & the excellent aging property of XLPE cable permit it to carry large current under normal (90°C) or short circuit (250°C) conditions. These cables can withstand smaller radius bending and is lighter in weight allowing for easy & reliable installation.
