Introduction

• 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 2.9.4.4 Annex U of IEC 60950 and subclause 2.10.5.4. Annex U of IEC.
  STW-B makes a merit of needing no interlayer insulation material such as insulation tape or barrier tape, trereby downsizing transformers a great deal, bringing about high efficiency and cost savings. Easier to design environmentally friendly transformers which can be easily disassembled and recycled. It is anticipated that Young Chang Silicons's STW-B will play a role in a widening range of fields.
