ABSTRACT:
An apparatus and method for lubricating a sheathed cable in situ. To lubricate a sheathed cable (300), an access aperture (304) is first cut through the sheath. A file (400) may be used to create the access aperture. A cable lubrication applicator (100) includes a top plate (102), a bottom plate (112), a lubrication fitting (110), and fasteners (106) that hold the top plate and bottom plate clamped around the sheathed cable, at the access aperture. Once the applicator is installed, a lubricant is injected into the sheathed cable through the lubrication fitting. After lubricating the sheathed cable, the applicator is removed, and a sealer (200) is installed over the access aperture. The sealer includes a top plate (202), a bottom plate (214), a gasket (210), and fasteners (206) that hold the top plate and bottom plate of the sealer together, with the gasket covering the access aperture. The sealer prevents the ingress of corrosive materials into the access aperture and the leakage of lubricant from the sheathed cable, and in addition, restores any structural strength to the sheathed cable that was lost when the access aperture was cut into the sheath.
