摘要： A method and apparatus for installing and recovering transmission cable. The apparatus called a termination box (1) has a stationary winding barrel (2) having a central axis, and a transmission cable guide (10) rotatably coupled to the stationary winding barrel for guiding a transmission cable (5) onto and from the stationary winding barrel (2) by being rotated around the central axis. Various methods show the step for winding and unwinding transmission cable from the termination box; as well as, use of the termination box in conjunction with a strength wire to install transmission cables between a transmission supply point and a transmission receiving point or points.
