Hi folks I need some guidence on this. There's a 3phase overhead power supply feeding exterior accommadation at a hotel. What it seems they've done is taken the cable out at the chimney area at either end and then split the phases like you see on an electricity pole (wish I'd taken a pic). The owner wants me to run a new supply accross as the existing cable/wires look very worn to say the least. I was planning on supplying a 5 core 25mm swa and joining it at either side in the attic space and using a catenery wire to support it. The span is at least 40m. To me it's a very long for one span with only support at either end especially with a 25mm 5 core swa. The owner's not for going under ground at all so I'm kinda struggling a bit with this one. Any advice would be appreciated
Thanks
Donny
