Here's a look at some of the features and differences between these two types of cables.




  • Solid core sheathed cables are typically used for mains power wiring. These are also known as armoured cables as they contain several metal wires wrapped in flexible steel tape.

  • Stranded cables, on the other hand, are much thinner. Due to their flexibility, these cables are used for wiring for telephones, satellite TV, and other low voltage applications.



A qualified electrician should be consulted for suitable cables for a particular wiring job. Plus, it is a must to follow safety protocols and standards when dealing with electricity.
