Abstract
Disclosed is an improved method and apparatus for installing a cable into cable guide tubing and the like. The method typically includes rotating a reel of cable guide tubing at least 360° while, using compressed gas, feeding a cable, such as a plurality of microducts, into the cable guide tubing. The related apparatus includes a cable injection unit and a rotation coupling unit to facilitate the installation of cable (e.g., microducts) into the rotating cable guide tubing.
Claims9
A method for installing a cable into a duct, comprising:
- inserting a cable into a free end of a duct, the duct being wound on a reel;
- simultaneously directing a flow of pressurized gas into the free end of the duct to facilitate the installation of the cable into the duct along most of the duct's length;
- and
- simultaneously rotating the reel about its central axis for at least a full rotation in a way that maintains the reel in a substantially steady vertical position.
A method for installing a plurality of microducts into cable guide tubing, comprising:
- (i) providing a reel of wound duct, the duct having an available free end for the installation of one or more microducts;
- (ii) inserting a plurality of microducts into the free end of the duct;
- (iii) directing a flow of gas into the free end of the duct to facilitate the insertion of the plurality of microducts into the duct;
- and
- (iv) rotating the reel about its central axis for at least a full rotation, thereby effecting the full rotation of the free end of the duct at the point of microduct insertion;
- wherein steps (ii), (iii), and (iv) are performed concurrently.
