What is Cable ? A cable is most often two or more wires running side by side and bonded, twisted, or braided together to form a single assembly.

Types of Cable Single core Cable 2 core Cable 3 Core Cable Armoured Cable Unarmoured Cable

Single Core Cables A single core cable consists of stranded conductors twisted together and housed in a PVC covering. It comes as a 6 mm sq. single core, colour coded green and yellow, and is used for supplementary earth bonding.

2 Core Cable In 2 Core cable, one conductor acts as a face and another acts as natural conductors, both the conductors have equal cross sectional area. It is used in telephone service and to connect computer devices

3 Core Cable In 3 Core cable all the conductors have equal cross sectional area. 3 strands carry R,Y & B phase respectively It is used as a Neutral wire.

3.5 Core Cable 3conductors are having the same cross sectional area & are used for 3 different phase. Therefore this conductor is treated as half conductor and hence the name is 3.5 core cable. It is used to carry the Neutral Current.

4 Core Cable In case of unbalanced load some neutral current exists. Therefore in some cases 4 core cable is proffered. It is used for lighting, load distribution & applications where unbalanced loading conditions occur frequently.

Armoured Cables It consists of one or two layers of galvanized steel wire or steel tap. It is used protection against mechanical injury.

Unarmoured Cables Constructions of unarmoured cables are same as that armoured cables expect that Unarmoured cables are not provided with armouring. Unarmoured cables also consists of all parts such as insulation metallic sheath, bedding & serving.
