The Important Differences Between Single and Multi-Stranded Wiring
Single Stranded Wiring:
This type of wiring is typically less expensive to manufacture than a multi-stranded wire as it does not require as much processing.
Single stranded wire is not as flexible as the alternative. This lack of flexibility can increase the likelihood of metal fatigue and the wire snapping as a result. Because of this, single stranded wires are best suited for products that won’t encounter much movement.
This type of wiring is often only used in smaller gauge wiring applications as it can be difficult to maneuver and utilize a heavy gauge, single conductor wire.
This type of wiring has a higher cost due to the need for more rounds of extrusion and stranding.
Multi-strand wiring is more flexible and less susceptible to cracking and metal fatigue than single stranded conductors.
This makes it the preferable solution for wiring that will need to maneuver and bend without experiencing metal fatigue.
The increased surface area of multi-stranded conductors decreases the amount of resistance that currents or signal passing through the wire will encounter.
Multi-stranded wiring can create challenges when soldering connectors or terminals as it can be difficult to ensure that all of the small strands have been soldered properly. If this type of wire is soldered, it is good practice to tin the wire first. This type of wiring is better suited for use with an application that requires a crimp connector. The small, flexible strands of wire typically crimp easily and mold to the crimp connector very well.
