Hi all members.
Does any of you have experience with using lacker-isolated solid copper wire from transformers instead of the colour-scheme multicore wires supplied by Märklin and Viessmann and others?
I think I would like to try it out on my next conversion.
I am aware of the hazards of possible shortings if the wire is rubbing against a sharp metal corner or otherwise damaging the coat of lacker, also due to not being flexible it is not suited where the decoder is situated in the slepptender and between cars/coatches.
The advantage as I see it is that a solid wire is easily shaped and soldered and the supply of it is plenty from the secondary coil of just one standard pluggable 240V to low volt transformer. Also the diameter is smaller than the overall diameter of the multicore wire. See the picture below. As for the conduction capabiliy, I think that the solid wire being thicker than the multicore wire compensates fully for the smaller surface compared to the although thinner multicore having a larger surface to carry the current.

Yes!

Svein has plenty of orange wire he can give you, Benny!

I'd stay away from it. If you want to move/replace the decoder, flexible wires will give you more room to play with (and less chance of breaking). Also, you'd lose the colour coding of the wires which would make fault diagnosis or decoder replacement more tricky. I've had plenty of occasions where I had to re-solder the wire that goes from the field coil to the brush plate, especially when I "just quickly" wanted to give the motor a clean...

Where I do see a use for this wires is where where space is very limited, or where you actually want the wire to stay in place, e.g. along the inside of a loco roof or body.
