ABSTRACT:
A cable is installed in a protective duct or guide tube by means of blowing (and, optionally, synergetic pushing) and lubricating the cable during installation. Lubricating the cable is done after the cable exits from the cable blowing equipment and hence takes place in a pressurized airflow passage. A hollow chamber filled with foam-plugs saturated with lubricant forms the cable lubricator. Lubricant is wiped onto the cable as it moves through the pressurized lubrication compartment. A portion of the airflow used for propelling the cable during blowing installation is bypassed around the lubricator and injected into the duct trajectory downstream of the lubricator.
