Cable sizing

[nero]

Can anyone help me out with sizing two cable please? I dont have access to any of my reg's.

Cable is in a duct,
210 meters long,
3phase machines @ 225KW and a 3phase machine @ 500KW.

Cheers

nero can you give any details about the machines? just curious about it

I hope those ducts are big enough to hold these cables, let alone being able to draw the cable in over that sort of distance??


I can see you having some major problems here using ALLY cables. How are you intending to draw these cables into the ducts?? Because if not done properly you can quite easily seriously stretch those cables. You'll need a constant torque electric/mechanical cable pulling winch with a saftey clutch, ....Use anything else and your going to be in some real trouble!!!

I dont have the exact machine. I was just asked to size the cables for someone pricing the job. a wind turbine @ 225KW and a 500KW machine.
