5 core SWA 120mm pvc cable

[Wilko]

Good luck pulling that size of cable over 250m.

Quick look at 5 core 120mm says over 9 ton per km. So a bit more than Wilko can manage before breakfast.

Definitly need rollers on this job.

Using even 200m of 4 core 120mm (can't find the weight for 5 core) cable will weigh just over 1480kg.

Not just damage caused by catching debris in the trench. At that weight, pulling with a tractor without rollers will likely stretch and damage the cable anyway.

End up being 95mm at the tractor end.

In all fairness to the OP if you have all the correct equipment let us know how it goes.

You'll need more than 1.

You'll need to position them along the length of the run.

Multiple of something like this:

Rather than pull the cable from a stationary drum and pull it over numerous little rollers wouldn't it be better to move the cable drum along the trench and unwind the cable directly into it? No need for little rollers then..

I'll let you try and control rolling something that with the drum included is probably more than 2 tons. I wouldn't want to.

You would have to control the drum if you are pulling the cable from it..
I've seen big reels of cables on wheeled units. The OP says he is going to use a tractor. I don't see a problem, if using the right equipment.

He needs to decide what is happening with UKPN first before worrying about what size of cable to get.
But before that you need to know what size supply is actually required.
There's no point getting a bigger transformer installed if the current supply will do the job.

To get 100A over that distance I would hazard a guess at 2x 120mm in parallel, but that is just a guess.

Hi Dave did you get my message not sure I managed to send it successfully?

Yes it’s something like that which I am borrowing ( not for ladder and the broomstick )
