DEVICE FOR WINDING FIBER-OPTIC CABLKE ON CARRYING WIRE Russian patent published in 2007 - IPC B65H81/08 

FIELD: electric power lines.

SUBSTANCE: invention relates to air laying of fiber-optic cables, particularly, to devices for winding fiber-optic cable on carrying wire, including devices for winding fiber-optic cable onto current-carrying wire or overhead ground-wire cable of power line. Proposed device for winding fiber-optic cable on carrying wire contains frame coupled with rotary drive found outside the frame and made for rotation around carrying wire, and reel for winding fiber-optic cable installed inside frame for rotation square to axis of rotation of frame. With device moving along carrying wire, fiber-optic cable is wound off reel and is wound on carrying wire at definite pitch along spiral. Reel is made in form of two drums secured on common shaft symmetrically relative to carrying wire, shaft being fastened by ends of frame from inner side. Fiber-optic cable is wound on both drums and transitions of fiber-optic cable from one drum to the other are provided so that angle between point of slipping of fiber-optic cable from one drum and point of getting of fiber-optic cable onto other drum in projection onto plane perpendicular to axis of rotation of reel is approximately 180 degrees. Inner walls of drums are provided with cutouts of definite form with rounded off edges which provide smooth winding off of fiber-optic cable when changing over from one drum to the other, and radius of curvature of fiber-optic cable not less than critical radius of vending of fiber-optic cable. Tensioner is used to maintain required tension of fiber-optic cable being wound on carrying wire. To kill jerks of fiber-optic cable when changing over from one drum to the other, spring jerk damper is used. To preclude rotation of rollers through which drive rests on carrying wire, around carrying wire balancer is used being attached to rotary drive.

EFFECT: provision of reliable and quick winding of fiber-optic cable.
