Cable reels are used for storage, unwinding, and winding of conductive cable or lifting cable.  Electric cable reels have contacts for maintaining live power during winding.  Reels are devices around which lengthy, continuous items such as cable, wires, paper, etc., are wrapped for transportation or storage. Reels are available as simple storage devices although more advanced styles are self-winding. They are also available with live connections that allow an item like a hose or electrical cable to be used while still on the reel.
