Subject: Topband: transformers, teflon tubing
I've noticed use of teflon tubing in a Flag family transformers.
Apart from low losses: is there another reason to use teflon coated wires?

73 material is conductive. The holes are lined with insulation to prevent
the enamel coating on magnet wire from scraping off and shorting to the
core as it is being pulled through the holes.
Also, it is easier to get more turns in a winding using Teflon wire vs.
some other types. The latest
Enamel-insulated magnet wire easily gets knicked going around the sharp
corners of a core. Although the core isn't very ohmically conductive, a
knick at a corner is enough to affect the operation of the transformer.
I think the old Clifton Laboratories page had a little section of
measurements of
Minimize inter-winding capacitance.
