ABSTRACT:
An apparatus for treating air core cables such as air core plastic insulated telephone cables, which includes a treatment tank provided with air and liquid application piping; an air application saddle or fitting and at least one liquid application saddle or fitting applied to the telphone cable in spaced relationship, with air and liquid application connections extending from the saddles; and a cable block sealing a segment of the air core cable to be treated. Air and liquid are applied in sequence to the plastic insulated cable pairs located in the cable, in order to clear water and other fluids from the cable and restore electrical transmission through the cable pairs. A method for treating air core cables such as air core plastic insulated telephone cables, which includes the steps of blocking the cable to isolate one segment of the cable, cutting spaced windows in the cable segment, applying an air application saddle and at least one liquid application saddle in spaced relationship over the windows, forcing air through the air application saddle and the cable to clear water from the cable, pumping a treatment liquid through the liquid saddle to restore the plastic insulated cable pairs and forcing more air through the cable segment to dry the cable pairs.
