Which Wire Can Carry A Higher Current? Stranded Or Solid

Share:
When we compare Solid wire and Standard wire, solid wires are constructed of one single piece of metal where Stranded wires are made of multiple small strands group together to make up a single wire or conductor.

Solid wire is tougher than a stranded conductor but rigid and less flexible than a stranded conductor.

Hence, solid wires are more likely to break if it is frequent flexing.

Both wires are suitable for domestic and commercial usage but which wire can carry a higher current standard wire or solid wire?


Yes! Stranded wire because the current will not be inside the wire but it will be in the cover of each thin wire in the stranded wire.

It is the multiple stranded wire that carries high AC currents due to "skin effect".

A solid wire can take a higher current in case of low frequency, but in high frequency like RF, solid wire carries less current due to skin effect.

Now for DC currents, it is still the multiple stranded wire since now the crossection area of the core is utilized for this case.

In case of heating in a stranded wire due to the flow of high currents, there will be an expansion in the strands and hence cooling up the wire.
