1. Application
This specification is to be applied for Triple Insulated Litz Wire (STLZW-B; hereinafter referred to as the "wire") using the winding or the wiring such as high-frequency operating electrical machine and apparatus.

2. Cable Construction

A. conductor (Enamel Coated) : Enameled stranded wire
B. 1st Extruded Insulation : Polyester type resin
C. 2nd Extruded Insulation : Polyamide compound
D. 3rd Extruded Insulation : Polyamide compound
 

 (1) Conductor
The conductor shall be used the enameled stranded copper wire specified in KS C 3107or JIS C 3053.
 

 (2) Insulation
The insulation covering shall consist of triple extruded layer (1st: polyester type resin, 2nd and 3rd layer: thermally reinforced polyamide) which are at least equivalent thereto in quality, extruded on the surface of the conductor uniformity. The insulation layers so applied shall have no detrimental effect to the conductor and shall show no flaws or dirt. Further, the wires shall be such that the soldering is possible without removing of the insulation layer. The wire shall be satisfied with B rated (130°C) thermal index of IEC 172 and UL SUBJECT 2353 test condition.
 

 (3) Color
The color of the wire is basically yellow. Other colors are available on request.

3. Characteristic
The characteristics of wire shall be satisfied with Appendix 2 value accordance with the requirements for Section 4. Other requirement of characteristics than those covered by this specification shall be as given in IEC 60950 (Safety of information technology equipment including electrical business equipment) sub -clause 2.10.5.4 and Annex U. The rating voltage shall be 1,000Vrms and the insulation grade shall be the reinforced (test voltage 3,000V for 1min).
