      Triple Insulation Wire

      YOUNG CHANG SILICONE′s STW-B wire is designed to fulfill the requirement of Class B thermal index. STW-B is the insulated winding wire having reinforced insulation complying with subclause Annex U of IEC 60950 and subclause, Annex U of IEC. STW-B makes a merit of needing no interlayer insulation material such as insulation tape or barrier tape, thereby downsizing transformers a great deal, bringing about high efficiency and cost cutback. Easier to design environmentally friendly transformers which can be easily disassembled and recycled. It is anticipated that Young Chang Silicone′s STW-B will play a role in a widening range of fields.
      Ranges of Usage

      - Insulation : Reinforced Insulation

      - Rated Temperature : 105 ~ 130℃

      - Rated Volt : 1,000Vrms(Maximum) 's

      - Conductor : 0.20mm ~ 1.0mm(32~18 AWG)

      - Solderability : Solderable without stripping'
