context_page_description: An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy across large distances. It consists of one or more uninsulated electrical cables suspended by towers or poles.
  Since most of the insulation is provided by the surrounding air, overhead power lines are generally the least costly method of power transmission for large quantities of electric energy.
context_section_description: Because power lines can suffer from aeroelastic flutter and "galloping" oscillations driven by wind, tuned mass dampers are often attached to the line, to change the characteristics of the line's physical oscillations. A common type is the Stockbridge damper.
