TEX-E Wire

Furukawa Electric’s “TEX-E” opens up a new era of switching transformers!

Triple Insulated Wires “TEX-E Series” save insulation tape or barrier tape between the primary and secondary coils and contribute to realize size and cost reduction or high efficiency of transformers. “TEX-E Series” paves the way to the sophisticated switching transformers.

Feature of TEX series

The feature of TEX series 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. TEX series, 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.

TEX series fulfill various requirements.

Certified as reinforced insulation; three layers can resist up to 3,000 ACV for one minute.
The temperature resistivity is class E (120℃). Please refer to the list of Safety Standard about the details.
A lot of insulation systems by UL1446 are provided. Please refer to item of “UL1446; insulation system” in the page of acquisition status of overseas safety standards. And please ensure to check the chemical compatibility of wire with varnish, solvent or so on regardless with or without mention of these items in insulation systems.
Solderable without stripping insulation layers
Can be wound smoothly by automatic coiling machines.
Wide size range from 0.20 to 1.0 (TEX-E)

Update

As proof of TEX-E’s safety, more than 2,500 companies have used TEX-E since it was first introduced into the market in 1993. TEX series wire is widely used for mobile/smart phone chargers, game consoles, and other applications. Its application will expand to home appliance, LED lighting, and medical equipment now that TEX-E and TEX-ELZ are additionally certified by IEC 61558, and IEC 60601 certified condition has been reviewed.
