What is a Multi-Conductor Cable?

First things first, what is a multi-conductor cable? These are a unique wiring solution consisting of several insulated wires encased within a single protective sheath. 

This design is the main difference between a single conductor vs multi-conductor cable, and it’s what makes these cables so powerful. It enables simultaneous transmission of multiple electrical signals or power currents, making these cables ideal for complex circuit configurations. 

You can learn more about the advantages of multi-conductor cables in our blog. But to truly appreciate all the different multi-conductor cable uses, you need an understanding of the different multi-conductor cable types. They’re classified mainly as either shielded or unshielded.
