Tracking resistance of insulating material en.cmc.de

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… WebToray Cetex® MC1100 PPS is a thermoplastic BMC based on TC1100 UD tape using high strength fibers in lengths of up to 25.4mm (1 inch).
