Can anyone help me on what wire / cable I would need to connect a residential building plot to the electrical network where the distance from the grid to the plot is about 1 KM?
The local energy company have quoted about £40k for running a cable overhead from the network to the plot, but will not break down that figure between the cable cost and the poles etc.
Their quote included the following spec :
230v
18kVA
50 hertz
Single phase
2 wire
I am looking at the alternative of laying underground, digging the trench myself and am trying to work out whether that would be cheaper.
The guy I spoke to at the local energy company mentioned that in an underground set up the cable would be HV with a pole mounted transformer as the on plot point of connection. And that the cable would be "95." He declined to give any more detail at this stage re the cable specification.
At the moment I don't own the land and have not agreed a price, so have little standing. What I am trying to do is get a back of an envelope idea of the cost of an alternative to the quote from the local energy supplier, so I can work out whether the plot has any potential at all.
I have identified what I think may be the appropriate cable :
BS7870 Mains, Single core, Aluminium conductors, XLPE, CWS, MDPE, 33000v 70mm - 630mm
Fixed Wiring and Mains Cables - Round stranded compacted aluminium conductor, inner semi-conductive layer XLPE insulated, outer semi-conductive layer, semi-conductive swelling tape insulation screen, copper wire and tape metallic screen (35mm2), polyester tape/water blocking swelling tape seperator, extruded black MDPE outer sheath. 33000 Volts grade to BS7870, IEC 60502-2.
In a 95MM2 conductor size?

All advice gratefully received. I was told that there may be a DNO engineer on this forum?
