Cable reclamation method and apparatus by which moisture is precluded from entering or is purged from an electrical cable by injecting a two-part polymerizable compound in liquid phase into and along the cable. Any moisture present is purged through an outlet port distant from the compound entry port. The compound takes a permanent soft-solid set at normal ambient temperatures within a few hours as a paste-like gel readily removable at any future time to permit cable splicing and servicing operations. This soft-solid gel forms a moisture-proof nonconductive sealing barrier precluding entry of moisture and restoring normal cable operating conditions. The compound supply tank is pressurized with air or gas to transfer the compound in liquid phase into the cable, the pressurized gas being used initially to agitate and intermix the compound constituents. The supply tank is preferable mounted on a carriage to facilitate its mobility in the field and the tank access closure features dual safety locks requiring separate deliberate manipulation to release the closure.
Cable reclamation apparatus for injecting a pre-mixed two-part liquid compound into and along a sheathed electrical cable, through a compound entry port in the sheath of the cable, to purge the cable of moisture, comprising a gas-pressurized tank having compound dispensing hose means terminating in a charging means sealably engageable with the exterior of the cable around the compound entry port with the hose means in communication with the compound entry port, means for supplying pressurized gas to said tank to pressurize and dispense liquid compound therefrom and into the cable along said dispensing hose means, and mixing means, comprising means for bubbling pressurized gas through the liquid compound, for mixing the two parts of the compound before starting to dispense the compound into the cable.
Cable reclamation apparatus for displacing moisture within an electrical cable with a polymerizable compound initially in liquid phase as charged into the cable, said apparatus comprising:
