JYN1-40.5 interval move off ac metal-enclosed switchgear

Product overview

JYN1-40.5-type interval remove AC metal-enclosed switchgear (hereinafter referred to as Switchgear) Three-phase AC 50Hz single busbar and single busbar section system of the indoor sets of equipment, as accepted and 35kV distribution network of electric energy use.

The switching equipment performance to meet the requirements of GB3906 and IEC60298 and other standards, with a load of push-pull circuit breaker to prevent, to prevent misclassification error co-breaker. Prevent grounding switch in closed position close circuit breaker, prevent straying every room, prevent charged in by mistake when charged with grounding switch "five prevent" interlocking function.

Product features

Can be equipped with excellent performance ZN -40.5 fully insulated vacuum circuit breakers with arc performance, easy operation, maintenance and other advantages. Choose creep age distance, insulation good performance of large current transformer, voltage transformer, post insulator, SMC insulation partitions and contacts box. To make the switch equipment insulation level can be improved.

The transformer can choose dry type transformer, have no oil, flame retardant, running economy, free maintenance, etc.
