1. Application
This specification is to be applied for Triple Insulated Winding Wire (STW-F) using the winding or the wiring such as electrical machine and electrical apparatus.

2. Cable Constrution

A. Conductor : Tinned annealed copper
B. 1st Extruded Insulation : Tetrafluoroethylene copolymer
C. 2nd Extruded Insulation : Tetrafluoroethylene copolymer
D. 3rd Extruded Insulation : Tetrafluoroethylene copolymer

 (1) Conductor
The conductor shall be used the annealed copper wire or tinned annealed copper wire specified in KS C 3101 or JIS C 3102.

 (2) Insulation
The insulation covering shall consist of triple extruded layer with ethylene tetrafluoroethylene copolymer (ETFE). The insulation layers so applied shall have no detrimental effect to the conductor and shall show no flaws or dirt. The wire shall be satisfied with F rated (155 ) thermal index of IEC 172 and UL SUBJECT 2353℃ test condition.

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

3. Characteristics
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 3,000Vrms for 1min).
