Wow. I spliced drops when I worked for Bell Atlantic, I always loved finding and fixing the problem with a locator vs. laying a temporary drop and letting the contractor bill Ma Bell 500 bucks to come bury a drop. I did wonder how power slices were done, and now I know. Cool video. Interesting. I'm not the underground guy, but the aerial guy.
So satisfying seeing a real world installation in an actual manhole as opposed to a clean, controlled lab. Also, thanks for mentioning the old school lead splices that were probably installed 50 or 60 years ago. Ain't technology grand. 🤣
@@ruenruins I just graduated from my degree in electrical and electronic engineering and we had a module on underground cables. While it is true that you do not need a degree to do it, an engineer will have to supervise, and to supervise you need to know how to do it, and have done it before.
Why is there no mention of cleaning? Especially with sanding the shear bolt connector and getting that conductive dust everywhere. I hate shear bolts for that reason alone
Is there a local ground rod outside manhole to connect cable shield ground wires and metallic cable supports ? Will ground rod be required near every medium voltage cable splice manhole ? I believe ground rod outside manhole seem easy to install but can it be driven inside manhole as well for more effectiveness thru bottom of manhole? In the later, water may sip in manhole, if the opening at bottom is not sealed properly....I do not know what is common practice to install ground rods at manholes.
If you get a fault or contractors damage the cable whilst digging do you repair it with 2 straight joints or do you pull new lengths of cable between these pits?? I'm a jointer from the uk and we mainly just have the cables buried straight into the ground and in a situation of fault we would spike the cable cut the faulty joint or damage out and do two straight joints.
Big Mike Welp, in the city of Chicago, we would just remove and install a new stretch to repair fault. In the suburbs, we will located the fault and repair it with pieces of like cable and make joints
South Florida. Depends on the situation. If it's direct buried we do a dutchman like you said. Two straights. If it's in a manhole and we have enough cable we do a dutchmen as well. If the splice is short walled or the company wants to bill the utility more they pull new cable and we splice in both holes.
Can you refence the osha rule for protecting against difference in potential while repairing urd. From a possible fault somewhere on the system coming onto the neutral and the grounds. We're being required to wear rubber gloves and stand on rubber blanket now along with cutting windows to bond natural score cable while splice.
boa noite sou eletricista subterrâneo aqui no brasil em sao paulo trabalhamos aqui com 15 kv ,21kv e 34,5 kv sistema reticulado protetor Network. na distribuição primaria e secundaria ja tenho 8 anos de experiencia qual chace eu tenho de 01 a 10 de trabalhar com vocês ainda nao falo inglês mais pretendo fazer curso .
why does this look so much more sensible than the india splcing videos. this has a nice connector, bolt heads pop off and quick sand, boom you barely did anything and it looks great. in india they're twisting every strand of wire together.
Suggest a little better racking of the cable. Cable going into the splice should be as straight as possible to eliminate stress on insulating sleeves and avoid gaps that could introduce water into the splice.
Patrick Pikulski it creates a barrier between the metal (Concentic/flatstrap neutral strands and the conductor) and the insulation. The strands can potentially carry load and the conductor obvious carries electricity. There is also a layer of semi between the insulation and the conductor. That's why it's partially conductive
So, I’m confused. I’m interested in doing this work when I get out of the marine corps, but would this guys job title be a “cable splicer” or a “lineman” I have seen conversations where some dude wanted to be specifically an underground cable splicer and someone else told him to go through schooling to be a lineman and he could move onto the underground stuff later, but that credentials for linemen cover everything so it would be better for him to do that in order to have more opportunities in more areas than just “underground”...how much of this is true?
Job title would be cable splicer. Underground (Splicer) and overhead (Lineman) work is vastly different. You could learn a lot in line school that could help give you an understanding of how the electrical grid works, but the work you do in underground is much different.
UgSplicer 102 yes on the utility side..... overhead guys only trained on overhead... underground guys only splicing. I’m a journeyman lineman....went through an ibew craft apprenticeship. I can do splicing overhead substation and transmission 👊🏻👊🏻
The one doing this is a woman. And the 'cracked' lead joints are concrete encapsulated asbestos wrapped joints. The train of the cable mimickes the train of the lead cables. And you you see every step all the way through? Of course the cable was cleaned.
