These are several models of medium and high voltage distribution equipment, all compliant with the IEC 62271 standard, suitable for a 50Hz power supply frequency, and covering different voltage levels and application scenarios:
Voltage levels include 10kV, 11kV, 12kV, 24kV, and 40.5kV;
The rated current ranges from 630A to 5000A, with the KYN 28A-12 model covering the widest range (630~5000A), suitable for high-load scenarios;
There are both domestic models (such as the KYN series) and international brand models (Schneider Mvnex, Siemens NXAiRS), catering to different project brand preferences.
