Someone passed along a Link to a company that makes a conduit repair kit. I was wondering if anyone has seen or tried these?

Hello Bill,

We had a sewer contractor hit a interconnect line once and we used a piece similar to this for repairs. We sealed it with silicone and then wrapped it in duct tape. It was all low voltage (24v) and underground. This was about four years ago and we haven't had any troubles yet.

Is this thing UL listed? people like Carlon have made a Split Duct system we have used for some time when making similar repairs. The only drawback was that it wasn't listed. That's not a probelm for a utility, and truthfully, since it was a "non-permit repair" it wasn't too much of a problem for us either. This is nice since it seems to fairly small. Usually the operators we seem to come across aren't as dainty and we have to repair greater than 5' on average. Still, another nice piece of info to keep on hand.

(edit to shorten url)

Bill,
That looks like a darned good idea.
I know that I could sure use someting like this.
That company would sell millions of these over here with the builders we have here!. [Linked Image]

I wondered about the listing issue too, but
it's a great idea in any event.

US Coreman how are you doing?

Yes,
The product has received a UL94-5VA/VO rating and is currently in final review for UL classification (either 514B or, a new classification).

Bill, if you go to New York City's Financial District (where the telco is constantly ripping up the streets), you'll see these things used A LOT when they're doing a repair job.

The streets are so congested that the conduits carrying telephone wires are almost touching the pavement, I think, from underneath. Dig a foot or so deeper and you'll hit gas and water distribution pipes.

Sven,

I was down there last month walking around after doing some sightseeing with out-of-towners over at Liberty and Ellis Islands. I used to work in the city regularly 20 odd years ago but haven't been down there much at all in the last 15. It's funny, but construction seems ordinary and almost invisible after awhile.

This is a good point to bring up. For a ”dig-in” situation where the raceway wall has been breeched, probably the most important considerations are, 1.) Is the cable jacket/insulation undamaged? 2.) Are the conductors also unscarred?

For cable-jacket penetration, there are also materials like Raychem CRSM “wraparound” or “zipper” sleeves. energy.tycoelectronics.com/rrg/raychem_rrg/391941.pdf

Telecomm folks have a wonderfully descriptive term for subsurface cable damage resulting in signal impairment—backhoe fade.
