Supplementary Insulation Winding Wire FWX-E

Supplementary Insulation Wire "FWX-E" is designed for the application in Telecommunications Network Voltage (TNV) transformers.
  • Neither margin tape nor interlayer tape is required for transformers with FWX-E wires. As a result, even more compact transformers can be designed and produced with higher productivity and at lower cost. Fewer component parts are required for an FWX-E applied transformer assembly, compared to other conventional products.
  • Environmentally friendly transformers which are disassembled and recycled with ease, can more easily be designed using FWX-E.

Features
  1. Conforming to supplementary insulation under IEC and UL
  2. Falling into Thermal Index Class E (120C)*1
  3. Rated at 354V peak or DC of max working voltage
  4. Soldered without any insulation layer bared (stripped)
  5. Having extremely fine conductor diameters of 0.11 to 0.19mm

*1 : The UL certification requires an insulation system in UL 1446 for Class A (105C) or above in operation.

Dimensions
"FWX-E" is characterized by an extruded insulation layer of heat-resistant modified polyester resin and polyamide resin. This was designed and developed to aid solderability and eliminating the need for stripping and is extruded on UEW (polyurethane wire).
