The company has upgraded its indoor medium-voltage switchgear portfolio, focusing on the ZN63(VS1)-12 indoor high-voltage vacuum circuit breaker and the FKN12-12/FKRN12-12D indoor puffer load switch. The improved products provide stable core components for KYN switchgear, ring main units and packaged distribution systems.
The ZN63(VS1)-12 series uses a mature indoor withdrawable or side-mounted structure for 12kV systems, offering vacuum interruption, long mechanical life and reliable protection. The side-mounted version is especially suitable for compact switchgear installation. The FKN12-12/FKRN12-12D puffer load switch is designed for load switching and fault protection, and can be combined with fuses for ring main units, cable distribution cabinets and industrial circuits.
According to technical staff, the upgrade emphasizes standardization, modularity and system compatibility. By unifying mounting dimensions, interfaces and maintenance logic, the company aims to help switchgear manufacturers reduce design and assembly time, while delivering safer and more efficient medium-voltage solutions.
