摘要：An exhaust gas system for an internal combustion engine, in particular anelectrically heatable catalytic converter, includes a metallic sheath having tabs and atleast one electrical conductor extending through the tabs. An electrically insulating, gas-tight leadthrough for the at least one electrical conductor in the vicinity of the tabsincludes first and second successively disposed sections. The first section is closer to theexhaust gas system for electrical insulation and is resistant to temperatures up to 1300°C., but need not be completely gas-tight. The second section is farther from the exhaustgas system and is gas- tight and electrically insulating for temperatures up to 500° C.
