摘要： A system for adjusting a length of an insulating rod of a high voltage circuit breaker includes a clutch and a fitting. The clutch includes a thread with a given thread pitch, and the fitting includes a thread with a given thread pitch formed in coordination with the thread of the clutch. The fitting is adjustably coupled with the clutch by means of the threads and the fitting is configured to be fixedly coupled with the insulating rod such that with respect to an assembled state of the system with insulating rod and with respect to a longitudinal axis the length of the insulating rod is adjustable due to rotation of the clutch relative to the fitting.
