Also, the removal of a single cable from a group of cables is usually not possible. All cables in a conduit should be removed in bulk, and new cables installed. It is a thick, pourable liquid for convenient loading into conduit. It dissolves waxes, bitumen, soil deposits, and lifts rust. It also provides a lubricating film to ease cable removal once the cable has broken free.
Additional equipment required depends on the type of job.
A manual liquid pump is one way to get the Loosener in the conduit. For small conduits and short runs, a flexible funnel temporarily sealed into the conduit with duct seal mastic can also help. A cable puller with sufficient power is needed to pull the cable out once it has broken free. All circuits should be de-energized for safe operation. Do not work with liquid chemicals around live circuits.
