- A Major Underground crew from Centerpoint splices the A,B, and C phases of 15kV distribution lines for a cut around in a new manhole located in a substation just outside Houston, Texas. Host utility: Centerpoint Energy
Hello!
I like to watch these videos of this channel.
I am brazilian, I'm elrctrician here and learning english language because I love it, so I have a question: how can I make to work with you in a future near from here?
Thanks!
It was certainly interesting to see red, white and blue being used to mark the 3 phases/actives/hots on this USA installation. I do not know off hand what colours are normally used for phase marking in the USA but red, white and blue are the colours for Australia. I always reckoned in the USA white was always reserved for neutral... but in searching google, it seems there are no standard colours defined for the active conductors by USA standards (the N.E.C.), which boggles my mind.
For hi or low voltage?
we normally use color tape and 1 layer for a phase 2 layers for b phase and 3 layers for c phase on the primary.
black red blue is 120 brown orange yellow is 480volts. Cheers
Much thanks, that is what I had reckoned, but hence is why videos like this are so interesting to me. Always a pleasure to see how things are done around the globe, especially on this level since I really only ever really deal with domestic work. Cheers :)
Grounded conductor and/or neutral must be white or gray. Grounding/ground/earth must be green, bare, or taped green.
No harnesses?? How would they get rescued if something happened??
Why don't utilities Hipot test high voltage underground cable before commissioning? I've never seen them do it, even on new work. Most inside contractors test 5kv and up.
Here in Southern Florida we do hipot test when repairing existing sections of cable but not when it's new construction.
We use a VLF machine to test cable. Hi-pot is harder on cables than a VLF
I have one problem that I observe on that installation the pipe that being inserted on the cable have no cover protection, it is not a big deal but it must be covered so that the rats and other animals will not enter on the pipe, and it must also water resistant so that if something flood happened on the area it will not enter to the pipeline, so that the cable remain dry even the cable are already isolated.
Seems more complex,and time consuming than overhead lines.
Because underground cable is matter of fraction of inches where over head is not
Kinda long post....but I poured milk down the back of a floor model tv when I was very long. Needless to say, it went sparking and frizzing everywhere. This got me scared to death of being electrocuted. It's ok to laugh, but I was so scared that I wouldn't even change a lightbulb. I have over the decades..yes decades I said not years, lol....I have slowly gotten better. Now I'm still scared, but in a healthy respect for electricity way. How or what do I mean do you say? Well on a much smaller scale, I have spliced cable of 2 and 3 phases. Yeap you read right, and I love it. It's like wood widdling for some. Yes its unplugged 😂. My husband was an underground coal miner, and he spliced all the time. Well over the years, as I became less afraid of electricity, wires, and stuff, I have found and taken a love to splicing. I'm talking 2 and 3 phase or prong plug. Who knew,🤔😆.....
У нас в россии бы ножовкой пилили такой кабель.
Техника безопасности и оснащение на высоте, я восхищён, ребята. Лайк.
SuperVideo ! 👍👍👍
How do I get into underground distribution cable splicing work? Is a lineman school my first step?
DontLeaveMeLucile depends on the company. Some companies underground network departments are their own thing. Others are a combination of underground and lineman. My company is a combination of underground and substation.
Met-Ed in PA. Its good to get in a company where you learn both. The work is shit some days but because you know both you can pretty much go work anywhere in the country.
I Work for utilities for a university and we do all underground splicing as lineman. EPR splicing, trifurcations, and lead to lead splices. All of our switchgear is double ended for a loop system so we have redundancy feeding every building. We do overhead cutouts, airswitches and fuse replacements on our overhead powerlines as well.

Your not as good or as through as we are. The way your doing it, your not far off places like India.
