Line hose with jib.

[Hebrew]

Hi.Just a quick question.Well two.Firstly,do you guys pick up the conductor in the jib WITH the line hose on or do you slide the hose away and pick up the bare conductor?Secondly,have preforms been outlawed for rubber glove work in your area?We still use them exclusively(high salinity environment and bolts do not go well together) but I do not fancy putting on preforms on 795 hot or cold.Tell me what happens in your part of the world.Thanks.

If I am moving the energized conductor on top of the jib, I leave the hose on the conductor. Glad to hear you are going back to sticking Preform top ties, an art that has been lost is coming back.....wooo hooo!!!!

[Hebrew]

Sorry if I misled you.I meant preformed deadend grips.We lost the preformed top ties a while ago.#4 tie wire is the norm now.

Never been a big fan of those preform deadend wraps:( With enough cover up , like with everything else its no big deal. Using line hose with a jib and link stick is just a good safety practice.

[Hebrew]

OK.How about using the wire holder on the end of the jib to pick up the conductor.Would you pick up conductor with the hose on or slide the hose away.I say the rollers on the jib may damage the hose.

[lineman2010]

I normally wrap the line around the hose, have the line in house on top of the jib, or pick it with a link stick.

Really just comes down to the job at hand.

Most of the rubber we use is class 4 so it would be a real pain to stick in the jib head & when you are swinging the boom it would not roll in the head, so I always stick the bare conductor in the jib. As far as deadending the largest conductor we use is 556 & we always use a 2 bolt clamp for all of our deadends. I think they are easier & safer than preforms when working live. I know this is a little off topic, but for tangent poles all we use is mechanical clamps already attached to the insulators, much easier & faster & safer when working live, don't remember the last time I tied in with tie wire, but I have noticed this is more of the norm in the places I have seen in my travels in the states.

This has been brought up before and there is a really informative thread on the conductor being in the jib and the different techniques and perspectives of moving wire.

Thanks a lot for the input,guys,especially you,King.I will read all of the replies tonight.

Hebrew, your right King posted a grat link. I missed that one since I was working anice storm at that time.

Where did he say anything about sticking?


He didn't, but when he said performs where outlawed, I assumed top ties. So if you don't rubber glove them how would you install them? Also further in the thread he said he was talking about perform whips.

The 2 piece top ties are easy to put on with a stick. Wrap Locs, not bad. Only one very difficult I thought were those called Super Tops. From Chance I believe. I thought they were crummy.

The truck my crew is using right now is a fairly new Posi-Plus. It has the new style conductor head on it. The head positioned normally opens at the top, door can easily be operated with a stick, also the head can be tilted forward for better position when jibbing corners. They also make a larger version, same style, that will accept class 4 hose. I worked on Hydro One projects for a while doing 44kv pole changeouts live. Jibs are tested at 100kv per foot. Minimum 2' of glass for 44kv stick work. I always went another foot , not for dielectric, just extra reach, with all hydraulic jibs changeouts were relatively simple, always going to 5' higher pole. I have no problem with holding a live phase in a jib, with enough clean tested glass extended out.

You assume too much, not good. He said hot or cold, right. If dead, put them on with your hands. Tell me about sticks O great one, I need to learn.

WTF Sully,,,Mexico??? Really??? Hope your have'n fun and staggering around down there...This will be the second weekend in a row they had snow on the Ridge!!
Your old pal,,,,Squirrel:cool:

Are you sure about the 2' for 44kv? On the EUSA side of the house we are told 4' for 44kv, 28 kv we use 2' & everything below it is 1'.
I think we are using the larger jib head, but I am not sure because I did not know they made 2 different sizes, I can get class 4 in my jib head but it is real tight.

Check your safe limits of approach. Under 50kv restricted limits are 4' down to 2'.

Yes but, that is from your farthest reach, with only 2' of jib you would be within your 2' of reach. Again I know that EUSA is min of 4' of jib on 44kv maybe Hydro One is different I would just check.
