Very clean install. Like looking at a PC board, just a thousand times larger. I'm not a lineman. It's just enjoyable to watch people work with a high degree of attention to detail.
Nice video mate - in Australia we have banned cold shrink due to the poor adhesion strength over time, around 5 years it loosens up so it becomes ineffective. We also wouldn't leave the bar copper for the neutral exposed with the corrosive environment we have.
Thank you for all that you do for myself and for others.. you are all so awesome and so loved you have no idea!! My goodness.. I Love You all forever xs infinity and e=mc2 but Almighty God loves you all even more then that though!! Have a blessed & safe day and week every one.. Loving you all!!
Interesting, what are the "concentric neutrals" for? I never knew they had such a thing! Is this so that if the insulation fails, there will be a direct short? (Not leakage to earth, which could cause a shock hazard?)
+Benjamin “Ozias” Esposti It is to terminate the electric field around the high-voltage conductor. Without this, you would feel the field even with the insulation intact.
The concentric neutral has two main functions in MV HV cables. First it acts as a electromagnetic sheath so that the electromagnetic field created by the conductor inside the XLPE insulation gets redirected to the concentric neutral, almost like a secondary winding on transformer. There is voltage build up around the concentric neutral so that it must be grounded at one side only to neutralised the voltage. If you grounded both side, there will be a circulating current which will generate losses and causes heat. Second, it acts as a early warning device if the main insulation broke. If the XLPE jacket break down, it will short circuited the feeder and trip the main CB :) Please visit my channel
@@imadewn is there w anyway in a newer (last couple years in 34kv ) Power distribution system to recognize the fault or current between the jacket and conductor if it breaks down hard enough. or does it need to become a shunt and blow? most other utilities aka phone company strand cable company strand and many other foreign fiber cables lashed to strand that also bond to the power company MGN or vertical ground , Is there a potential there for danger? Your comment makes me very curious seeing many more of these types of cables recently.

Looks good, I dont know if the part where he sands and cleans the cable was edited out, thanks for the video
Thumbs up :D

What are shunt reactors for exactly? Is it just to limit internal transformer fault current?

Ola que bueno que estos videos se pronunciaran en español para poderlos aprovechar mejor gracias

Okay, neat. Yes I've held a high voltage cable before, and I know what you mean about the field around it. It's almost like static.
Its the neutral

What do they do with all the waste metal at the end of the week? I know guys who would LOVE to take it off your hands.
That wasnt right
