Which component is a stranded wire attached to supporting structures from which the Contact and/or Auxiliary wires are suspended?

Explanation:
The messenger wire is the structural strand tied to the supporting structures, from which the Contact and/or Auxiliary wires are hung. It acts as the backbone of the overhead system, providing support and correct spacing so the energized wires stay at the right height and tension. The pantograph on the train collects current from the contact wire, not from the messenger wire; a phase break isolates sections of line, and an MCB is a protection device, not the supporting conductor.
