A modified planetary gear box and arrangement of the gear box with a drive motor permits electrical, optical or other types of cabling or wiring to be passed through the planetary gear box along its axis of rotation. The planetary gear box drives or rotates a reel of coiled tubing. Electrical, hydraulic, optical and other types of line for lowering into a well bore through the coiled tubing is passed through a passageway through the center of the planetary gear box, into one end of a hub of the reel, and then into the coiled tubing, which is injected into the wellbore. The other end of the hub of the reel is able to be connected to a swivel joint that can be connected to a pump for pumping fluid into the coiled tubing.
