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.

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!

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

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!

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

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.

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

Yeah Agree, thats the main concern

Here is a better look!

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

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!!
