600M Electrical feed to farm house underground.

[steve eastick]

Good evening.
I have been asked by a client to size and install an electrical supply from a meter position located 600M from the property and consumer unit. The client wants the supply run underground.
Supply is 240v single phase 100A TNCS.
Could anyone assist with size and cable type recommendations?
Any one else run such distances at 240v on private land?
Thanks in advance.
Steve.

You say big cable, then say 35mm, make your mind up.

At 600m, I'd say the cable needed is likely to be a lot bigger than 35mm.

I don't think the OP will be coming back to this thread...

It would probably be cheaper to transform it up to around 660V or even 1kV and back down to 240 again at the other end.

Will look out for the same OP on the IET forum then

Even on a cursory 80A guesstimate I get 240mm² so I guess the Tx method as suggested by @davesparks or DNO supply.

Now you have just gone and spoiled it for everyone.. The OP will never come back now...

With the size and length of supply you mentioned the cable costs will be horrific, it will possible need to be parallel cable fed. I'd be looking at either getting the DNO to extend their MV network closer or Davesparks suggestion of stepping up to just below 1kV at the source end and down again at the destination.

How about using 'wireless power transfer'.....

In far-field or radiative techniques, also called power beaming, power is transferred by beams of electromagnetic radiation, like microwaves or laser beams. These techniques can transport energy longer distances but must be aimed at the receiver.

Sounds simple and will sort out all future shed/garage/farm house power issues...
100A over 600 meters is no problem now...

Hey @steve eastick
We know you’ve been looking at the responses very recently. (it’s on your profile!)

Give us your thoughts, or we’ll get bored and go to the pub.
Look, just say if you think you’ve bitten off more than you can chew. I think we’d prefer a honest update. Cheers.

Now he's seen my post #25 he has his answer.. He will never be back...
