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 K.K.
