Is it possible to repair a submersible cable? 5 HP submersible pump hanging down in the bay got chewed on by a sea lion or something and has a chunk taken out of the jacket.

I know it's not ADVISABLE to repair it, just wondering if it's POSSIBLE :whistling2:

I've done it using the heat shrink that has the glue stuff in it.

I don't know why it wouldn't hold up in salt water when it works just fine in sewer water........

I haven't looked at the cable yet, just talked to the dude on the phone about it.

Sounds like it's just the jacket, hopefully the heat shrink will take care of it. If there is conductor damage maybe I'll reconsider.

Our shop repairs sub cables on pumps daily... Not a 100% sure how they do it, but I know it is more than a butt splice and some heat shrink...

Heat Shrink Tubing
THICK WALL HEAT SHRINK TUBING
• ULListed.File#E123896.
• Installs and shrinks easily for labor savings. Effective insulating over large transitions. • 3:1 Shrink ratios enables wider cable range and fewer tubing sizes.
• Excellent abrasion, corrosion and environmental resistance properties.
• UV and Fungi Resistant.
Thick Wall Heat Shrink Tubing (HST) is used to dielectrically insulate and encapsulate electrical connections. The HST internal coating has an adhesive and sealant that melts when the tubing is heated to provide a moisture and soil resistant seal.

When I worked at a mine , we used to VULCANIZE damaged cables .

A procedure with different rubber tapes , and then baked in a mold oven .

Heat shrink cables with goo inside and call it a day.
Never had a problem with even 600v three phase submersibles. Those shrinks are made for that purpose. How do you think they terminate under ground primary lines?
Some stuff just larger! IMO

I make waterproof splices in submersible pump wire often heat shrink will work fine but you need an end to slide it over. If you just have some nicks in the insulation use rubber tape half lap it and run it two or three inches each side of nick.Make it three layers thick and stretch it as your winding it on. I usually put a few layers of 33 on top of that.

What about long term solutions to keep it from happening again?
This particular pump gets lugged in and out and moved from one place to another all the time. Cord gets draped on stuff, forklifts run it over, marine wildlife f*cks with it, etc. There are all sorts of things I could do with it but educating the employees to take care of electrical equipment is like pushing back the ocean.

At one chem plant we had some portable electric submersibles that the operators would destroy the cords on all the time, I heat shrunk the **** out of the cord then put old suction hose over the whole thing.

As they were hell on hoses too I always had a supply of hose to use. :laughing:
