Subject: [TN] Teflon and Tefzel Wire


>Dear Technet friends,
>
>We've been using tefzel (a modified teflon) insulated wires in our
transformer
>assemblies. Some people are concerned that the teflon's cold-flow property
would
>end up in shorts between windings where there are pressure points. My
questions
>are:
>
>- Is tefzel better than the unmodified teflon in this respect?
>- How is the cold-flow characteristic quantified?
>- Where can I find the "cold-flow index" of the materials?
>
>Yours sincerely
