40.5kV High Voltage Switchgear

1. Product Overview
The KYN61-40.5 high voltage switchgear is used for receiving and distributing electric power. Its main switch is ZN28A-12 vacuum circuit breaker which can be coupled with the CD10II electromagnetic mechanism or the CT8I or CT19B spring operating mechanism. The ZN65A-12 and VS types of vacuum circuit breaker can also be used. In addition, the GN30-10 rotary disconnector is adopted.

Our high voltage switchgear conforms to the national standard of GB3906-1991 and the international standard of IEC298. Its protection class reaches IP2X and it has outstanding blocking functions.
