Hello All, I have run into a wall and seek your collective guidance.
Background: EN 60335-1 references EN 61558-1 (Transformers), which references EN 61558-2-17 (SMPS Transformers) I'm trying to source triple-insulated wire that meets Annex K of EN 61558-1 (2005). Annex K is titled, Insulated winding wires for use as multiple layer insulation". Annex K of EN-61558-1 is similar to Annex U of EN 60950-1 but the requirements are more stringent than specified in EN 61558-1. For those unfamiliar with this type of wire, it is used to reduce the mandated creepage and clearances in Switch Mode Power Supply transformers and yields a much smaller transformer for a given rating. That's its claim to fame. To my knowledge, tri-insulated wire is manufactured by: Furukawa Rubadue * Virgina Insulated Products * * Requires stripping, which the transformer manufacturer is not fond of - they seek wire meeting this requirement - which does not need stripping of insulation. I cannot find evidence that any of them meet the Annex K requirements of EN 61558-1 There must be someone out in this World who manufactures such wire - but I can't find them. Helppppppppppppppppp me - please. Vendors - please contact me directly. ThanX and regards, Art Michael A.E. Michael, Dir. of Engineering PSI 166 Congdon St. East Middletown CT 06457-2107 U.S.A.
