Hello Judd,
The wire you refer to is "triple insulated" wire. It has three coatings
of insulation either wound or extruded over the conductor. It is
described in CSA 22.2 No. 950/UL 1950, Third Edition, Annex U, titled,
"Insulated winding wires for use as multiple layer insulation" and in
Section 2.9.4.4 titled, "Wound components without interleaved insulation".
I believe there are a few other suppliers of similar material.
I would expect that the source you identified could quickly tell you if
and where this product is used in a Listed or Certifed product.
My (related) problem is that I have run into difficulty trying to locate
an available Recognized Insulation System using this specially insulated
wire. If anyone knows of a "system" using triple insulated wire, I'd
appreciate hearing about it.
Regards, Art Michael, Editor
