Help - Metal Braided Sleeving for exposed Wire ?

[mobiledynamics]

Here's the deal.

I have a conduit running from the house that goes outside .
I plan to run a low volatage burial data line to that and where it exits from outside, I do plan to trench it back to it's intended location.


Is there some sort of SS wrap, metal braid, that exisits that I can use to protect the wiring from where it stubs out and then goes *back down* to the trench. It's cat6 burial rated wire

Use flexiable conduit. Cut easy. Ends go on easily.

I can't recall seeing a LQ Aluminum variant.
Only steel, and when I just loop it back down to the dirt, that steel would corrode....

 

[Movover]

Is the conduit in the ground metal or are you direct burying? how about just using liquatite? that will protect it with no issues

 

[mobiledynamics]

The current conduit is PVC and stubs out around 6" high out the ground.
I'll be coming out of this from the house and then going *down* as the path to the endpoint will be trench path.

I just want to add a bit of extra *protection* for the exposed cable . I've had my fair share of knowing what happens when landscapers do their thing..

Liquid tite flexible conduit comes in a pvc form. Commonly referred to as Carflex (although that's just a brand name....sort of like Kleenex or Xerox machine). Cuts to length super easy, fittings go on easy and it's not expensive.
Good luck

What size is the pvc youre using?If its 3/4" Id just buy an a/c whip at the box store and pull the wire out of it.
Then you can just cut it to length and add whatever extra fittings you need.

Or go to a supply house they have flex in aluminum.

The liquidtight non-metallic flexible conduit is not the most durable of materials, SCH 40 PVC is much cheaper & will hold up better to landscapers, a heat gun will make it easy to make any required bends.

you could use SS braided fuel / brake hose. Some have teflon liners or rubber. Fittings are optional .

Installing a data connection between buildings.

If it were me I wouldn't even consider a flexible conduit for sleeving an an underground cable of any type, above or below grade.

If your going through the effort of digging a trench, do yourself a favor. Do it properly and do it once. Life is too short for half *** redo's.

PVC conduit is the method of choice, it's easy, cheap, durable, and 100% watertight when done properly. It will last longer than you when placed below the frost line in your area.

For those pesky string trimmers and grass munchers, Schedule 80 PVC is extra heavy wall thickness and required where exposed to physical damage, as compared to the SCH 40 standard thickness pipe. Both types share common OD and fittings. Factory made bends and fittings are readily available, custom bends can be made with an oven, heat blanket, heat gun or torch when applied sparingly. It's non rusting and never requires painting. Be sure to use the gray electrical grade, approved for UV exposure. NOT white PVC intended for plumbing, it's not the same, and not listed for wiring use.

Couple pointers about data cable. Moisture inside of a data cable assembly can reak havoc on the data signals propagation and legibility, reliability. One tiny pinhole anywhere in the jacket of your cable, caused by an installation nick during the install is enough to let in groundwater and cause problems down the road. Quality direct burial data cables are gell filled (expensive) just for the purpose of excluding moisture and water, also a pain to terminate (messy).

A quality PVC conduit installation, water-tite, and the ends plugged with duct seal after the wire is pulled, will exclude the ground water and as importantly, the condensation that occurs inside the pipe from air traveling through. Due to the different atmospheric pressures at each end of the pipe. If the cable ever does go bad, or you want to upgrade to the faster stuff (GB or Fiber) in the future, no problem, remove the duct seal and pull in what ever the future brings, the digging and raceway placement is already done. With this method you really don't even need the underground rated cable, standard cable will work just fine as long as it stay's dry.

One last suggestion, to get around the digging and conduit installation, GO WIRELESS, with the proper gear. It's faster, cheaper, just as reliable as a cable. Just has a different learning curve. It can serve an area larger than just your outbuilding, say deck, patio, yard. Oh and can reach way further than the 325' that Ethernet is approved for. The connection I'm using now is from a half a mile away from me, works 24/7 with great throughput, cost $200 in equipment, and has been rock steady for the last 3 years, rain, sleet, snow ,ice, sun. You can't beat it with a shovel and a spool of cable...

2 of these would probably do you good, along with a little learning curve.

Put away the shovel and start reading up on it, you'll be glad you did.

Here's a primer, this has been covered on the forum a few times now, use the search function,

I've surpassed the budget on other things I've got going on.....

So here's the deal. I got a bid for someone to trench via a bullet and lay pipe.
Quote came out to 5K for a 2" pipe.....

So I'm sorta going to do this ad hoc....and just rent a trencher and run the line as planned for now. If I need to revisit it down the road, by laying pipe in trench, I will, but at that point, I would not use the exisiting pipe as that stubs outside as a coupling point but run a complete new pipe from point a to b.

The wire is not for internet. It's for a straight telco line

Regular flex conduit is prohibited for outside use.

How about some Liquidtight Flexible Metal Conduit?

It's got steel flex inside the PVC jacket. It looks like the plastic stuff, but it's much more rugged than the Nonmetallic junk.

It's even available at the Home Depot

 

[mobiledynamics]

Correct. FMC LQ was what I was thinking. I know there is steel FMC LQ. Will have to check to see if Aluminum FMC LQ exists
