HV Cable installation

[doogle]

This is a FINISHED hv cable installation,The cables come through the wall at approx 2m high and drop over approx 7m to the floor,Must be one of the worst installs i have ever came across

 

[telectrix]

did pikeys install it so it would be easier to lift come nightfall?

 

[Dan the spark]

Not a good standard at all, nice bit of ladder rack wouldn't go a miss there

 

[doogle]

Yes Dan that's what we were called in to do, For some reason they will not let the original installers anywhere near the building

 

[Dan the spark]

Not surprised lol

 

[johnboy6083]

That's horrendous. If they were still working there, I'd get rid anyway

 

[snowhead]

They could have at least laid it on top of the vent trunking and used sticky pads and tie wraps to hold them down!!

 

[Marvo]

Oh yeah, that's a world class installation. Doesn't it need ducting where it passes through the wall as well as there being an obvious lack of support? How on earth did they expect that install would be acceptable? Maybe they left or got thrown out before they had completed the job.....

Its probably best we didn't see the termination point if that picture is anything to go by
Who in their right mind can make a dogs breakfast like that

My worry would be:
Is there enough slack to make a decent job of it? If not you’re buggered.

It's not the size of the through crimp required, it's the size of the crimping tool that worries me!!!

Can you not just use wago connectors ,

If it come to using crimpers then there’s a though joint involved. Have you seen the modern ones? They look like a dog turd with a giant bloodworm coming out each end!

Have seen someone do a connection with Weidmüller clip on terminals. OK only low current, but the voltage could rise to 1450V.

They were all crispy and crunchy when I found them, didn’t take a lot of finding I just followed that horrible burning smell.

Oh Dear!!!

So where are the those cables coming from, also have they been direct buried along it's run, or is the installation all above ground?? I'm thinking this could be a Ring Main install??
Any chance of a photo, to what they are being terminated too??

 

[doogle]

They are a link between 2 11kva transformers inside the same building,All above ground,The whole run was a mess,The cable isn't lsf as requested so luckily it's all getting stripped out and redone, Total b**s up from day 1

When you say ''Linking'' do you mean via a main switchboard with bus coupler?? Otherwise why are there two cables?? As you only need one suitably sized cable to link 2 transformers, never ever seen two cables used in MV work!!

 

[Bobster]

I thought the standards of the new sites I've taken over are bad, makes them seem a lot better looking at this.

Sorry mate could have been clearer,one from each transformer, They drop through the floor into 2 ringmaster units

Ah, ... so these 2 cables are the feeders to the 2 transformers from the load Switch Fuses/Breakers on the RMU's. ...OK, got you now!! lol!!
