JYN1-40.5KV switch cabinet series three-phase AC 50Hz single parent system, a set of indoor unit, for receiving and distribution of 35kV network circuit with. This type of switch cabinet has to prevent misoperation circuit breaker, prevent loaded a handcart, prevent charged hang ground, prevent take ground transmission, to prevent mistakenly charged interval (hereinafter referred to as the "five anti"). The cabinet can be with Zn] - 40.5 double fracture of vacuum circuit breaker and ZN23-40.5 single fracture of vacuum circuit breaker and circuit breaker.

This equipment complies with the national standard GB 3906-2020《Alternating-current metal-enclosed switchgear and controlgear for rated voltages from 3.6 kV to 40.5 kV》and IEC 62271-200《High-voltage switchgear and controlgear – Part 200: Alternating-current metal-enclosed switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV》
