Not such good tray work.

[High Tower]

So working in. Shopping centre and admiring the awfull tray work in the carpark.

Look what I found, this is the 11kv tri for the TX. Nice!!, think its safe to say that in this case the tray bond was required.

 

[Bobster]

Jesus! How can somebody just walk away from that.

The cable istallation is bloody terrible!!

they should be securely cleated and if triplex is used, special cleats are available, that maintain the twist of the trefoil.
id be ashamed to leave that!

 

[Guest55]

god i hate curly bond links.
;-)

Oh the cleats are up there but only maintaining the tri. It's just lying on the tray not even bothered with zip ties

 

[Kamikaze]

It would have taken longer to put the earth link on than it would have done to cut the flange and bolt the two trays together. :frown:

 

[KAS1]

There would of been no problem on ladder rack

 

[monkeyelectric]

They got paint on the cables, thats terrible!

 

[Stroppy]

Its curly to take up the movement when the separate trays flap about in the breeze.

i know why its done lol , just looks rubbish

 

[Robert Turnbull]

And then put a danger notice under the tray and paint over it

Ive seen worse M8 TBH, it isn't great admittedly, but not a gasp situation IMO, although a rough Job.

 

[Bobster]

It's more the bent over tray that's pressing into the cable that bothers me.

Yeah Agree, thats the main concern

 

[High Tower]

Here is a better look!

 

[Engineer54]

Totally down to the site supervision, both from the contractors themselves, and the clients supervision!! Or should i say the LACK of it!!! lol!! The installation as shown, is a potential disaster waiting to happen to be honest!!

 

[Gage]

Here is a better look!

Very surprised that tray hasn't cut in to the insulation yet

Is that roof plasterboard? Lol

​

No, it's concrete!! What your looking at, is bad form shuttering joints that haven't been ground down!!

That is the roughest tray job i've seen ever! Its an accident waiting to happen

 

[Engineer54]

The worrying point of this installation for the 11KV cables, is that MV cables don't like any areas of ''point pressure''. It can/will over time create a weakness at that point, where the higher voltage can penetrate the insulation to the semi conductive layer and on to the copper screening foils/tapes and beyond!! Seen this phenomena with MV/HV cables a good few times before. The problem is not so much the metal tray slightly penetrating the PVC over-sheath, it's the voltage trying to break through any weakness in the boundaries put in place to contain that voltage!! It's not as simple as your normal LV cable situations!!

 

[Sintra]

That's terible a nice gusset bend in there would have done the trick. Bet the cable was short when it was pulled in and they've done that to gain a few inches lol.

 

[Gage]

Bet they're cowboys. Horses, revolvers the full works!

 

[trev]

If you were the senior guy on that site would you have allowed that to remain in place? I know I wouldn't have.

 

[High Tower]

Ok now I'm going to tell you that that is a shopping centre car park, the trays are on the ceiling and can easily be touched as the trays are only about 6'6" off the floor, very low ceiling indeed.

Should be nicely formed in that tray with tray lids. Yeeeeehaaaa

 

[Thomas21]

That's a joke

 

[GLENNSPARK]

Here is a better look!

i`d say its been belted by something has that....as theres evidence of impact on the tray fixed to the wall as well..

 

[Silly Sausage]

It was me in the works High Roof Transit doing handbrake turns one night.
Luckily there was a few cans of white spray in the back.

is that a `bangsy` then Archy?

 

[Gage]

To be honest it looks like it's buckled or they've half arsed tried to bend the side.

But the bottom one has definitely been hit

 

[Marvo]

I also think someone might have driven or reversed a vehicle into it. It's difficult to say without seeing it from further away but the height changes on the right hand tray don't make sense even as a cowboy install job..

 

[High Tower]

No if you look at the first pic it's been bent to allow the cables over, it's at that angle because of the weight of the cable and not enough support

looking at that, I would say that the tray has most likely been put in by some underpaid labourer who wasn't interested, they have put this in before the steel work was even finished hence the jotum spraypaint all over it, then they probably got paid off during the usual agency rotations, the job was probably behind on the concrete or something similar......the cable pullers have been in and pulled it over the tray with a few cable ties to get it to turn in the way they wanted it, they would have been in and out as fast as possible, then the steelwork got finished and sprayed white, going onto the tray and cables at the same time...

you can see it was done fast and untidy, the screwed rods are all odd sizes etc...and the ends are bent where somebody has been shoving an alloy tower about to put the cables on there....
