Transformer Using TIW-B 0.4mm Enameled Wire Copper Triple Insulated
Wire
The feature of triple inslated wire is in its insulation layers.
IEC standards require specified insulation between primary and
secondary coils of transformers. And the standards do not accept
general enameled wire as insulation therefore insulation tape or
barrier tape are required in transformers using enameled wire.
Triple insulated wire however, has triple insulation layers which
comply IEC requirement and therefore can be used without barrier
tape or interlayer tape between primary and secondary coils.
