Feature:
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.
