The Comparative Tracking Index (CTI) is used to measure the electrical breakdown (tracking) properties of an insulating material. Tracking is an electrical breakdown on the surface of an insulating material wherein an initial exposure to electrical arcing heat carbonizes the material. The carbonized areas are more conductive than the pristine insulator, increasing current flow, resulting in increased heat generation, and eventually the insulation becomes completely condu… WebComparative Tracking Index (CTI) Volume resistivity IEC 60243-1 kV/mm IEC 60250 IEC 60250 IEC 60112 IEC 60093 -V Ω･cm 26 4 0.003 175 1016 Molding Condition Cylinder temperature Mold temperature - - ˚C ˚C 300-340 130-150 a: Flow direction/Transverse direction b: P=150kPa, V=0.3m/s, PPS vs. carbon steel c: UL file No. E53829
