Title essentially. What advantage does having loads of fibres have over one solid piece? Flexibility?
In: Physics
Exactly right, the smaller wire-strands and jacket type make that kind of wiring much easier to work with. Think about the power cable for your TV or charging cable for your phone being difficult to bend.
Some wiring (like in your walls) is a solid strand of copper, but it doesn’t need to be flexible and doesn’t move after being installed.
A solid stand would get more stress being constantly bent over and over, and would break quite quickly.
