Discuss 5 core SWA 120mm pvc cable in the Commercial Electrical Advice area at ElectriciansForums.net
End up being 95mm at the tractor end.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.
Thanks Rob- yes have got a roller organizedDefinitly need rollers on this job.

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.
Hi Dave did you get my message not sure I managed to send it successfully?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.
Yes it’s something like that which I am borrowing ( not for ladder and the broomstick )View attachment 51907View attachment 51908 this might help, or a broom stick through a ladder .lol.

Hi Dave , you interested in helping ? Keen to move forward. Many thanks IanYes I have got your message, I'll reply later whne ive got chance to read it properly.
Re the cable costs have you looked into doing it in multiple AWAs?
Also why the 5th core? Do you need to an earth conductor?
A few years back (2011), installed a 4c 240mm swa with a separate 240mm earth. We hung the reel from a 5 ton digger bucket and unreeled it that way. 105 metres. I think it cost about 8k.
240mm earth with a 240mm cable?
