Had reason to pull a cable out of a conduit due to damage from others work. Cable is about 7 years old. The cable is meant for direct burial and was in a buried PVC conduit. The jacket is cracked in numerous places along the length. Some of this may be from tension from breaking the conduit at one end with construction equipment but it appears the pull lube interacted with the cable sheath. I am trying to get information on the sheath material. Lube is Ideal 77. I see that they say not for low density polyethylene so I am guessing that may be the material. Their 77+ is a different formulation and "recommended for all cable types." Now I am faced with what to do when replacing this. The options seem to be:
- clean out the conduit (replacement is not practical). This isn't going to be easy and likely not very effective but I could pull something through to get some of it and/or run soap and warm water through it.
- coat the cable with something to protect it - not sure what that would be...
- put tubing over the cable. It's a bit less than 1/4" diameter so there is lots of room. Run is about 60 feet. Conduit is 3/4".
- just replace the cable (and attached sensor) and expect to replace again eventually. It's low voltage so isn't a safety issue. Based on the previous one it should last at least 10 years if undisturbed.
Any suggestions?
