Generator circuit breaker cubicle D-17G type, air-insulated, is dedicated to lead out generator’s power with nominal voltage of 12 kV and 17,5 kV.
Application control and supervision systems allows generally maintenance-free operation of the generator circuit breaker cubicle with motor drives (operating of disconnector and earthing switch).We offer a series of applications of the generator’s circuit breaker cubicle. The presented design solutions are exemplary and thanks to a very experienced construction department, we can modify and execute them depending on the needs and requirements which is important in the case of retrofitting existing installations.For each generator’s circuit breaker cubicles D-17G, declaration of conformation is issued.
