Two 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.

Three 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.

Core Cable-3.5

• 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.

Four 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
