Neatness is important to keep minimum voltage difference between turns. a layer of insulating material between layers of windings is good practise although it makes the transformer coil bigger.
Usually the secondary is closesd to the iron yoke. |
That depends on the voltage per layer. Mains transformers generally don't need any insulation. I's only when you start getting intohigh voltages (over about 1kV) that you have to worry about insulation.
