Twisted wire harness can improve the bending performance and the tensile strength, reduce the size of the cable (you can also arrange the core wire reasonably) to make the cable more round and the appearance beautiful, increase flexibility, and improve corona phenomenon.
So what is the role of the twisted wires?
The twisted-pair electronic connection wire has twisted-pair and triple-stranded wires, etc. They mainly plays an anti-interference role, preventing external electrical appliances or wires from interfering with their own signal, and also preventing theirself from interfering with other appliances or wires. The shielded wire have stronger anti-interference ability than the twisted wire. Shielding wire is in the outside of the twisted wire wrapped in a layer of mesh copper, aluminum mesh or copper, aluminum foil, which can transmit the interference signal to the ground, avoid interference signal into the inner conductor interference and reduce the loss of transmission signal.
