FAQs

What is the rated voltage and current range of the KYN28-12 switchgear?
The KYN28-12 armored withdrawable metal-enclosed switchgear supports rated voltages of 3.6kV, 7.2kV, and 12kV, with rated current options ranging from 630A to 4000A. The rated short-circuit breaking current goes up to 50kA, making it suitable for high-demand industrial substations and utility power distribution networks. You can download the full technical datasheet to compare parameter configurations for your project.

Which international standards does the KYN28-12 comply with?
The KYN28-12 is fully compliant with three major standards: GB3906 (3~35kV AC metal-enclosed switchgear), GB/T11022 (common technical requirements for high-voltage switchgear and control equipment), and IEC298 (AC metal-enclosed switchgear for rated voltages above 1kV up to and including 52kV). If your project requires documentation for customs clearance or engineering approval, you can request certified test reports from our team.

What are the installation environment requirements for the KYN28-12?
The KYN28-12 is designed for indoor installation at altitudes up to 1000m. The ambient temperature must be between −15°C and +40°C, with relative humidity not exceeding 95% (daily average) or 90% (monthly average). The installation site must be free from corrosive or flammable gases, water vapor, and significant vibration. For projects in high-altitude or extreme-climate regions, please contact us to discuss customized configurations.

Can the KYN28-12 be used as a high-voltage generator outlet?
Yes. The newly developed high-current, high-breaking version of the KYN28-12 can be deployed independently as a high-voltage generator outlet switchgear panel, in addition to standard incoming and outgoing feeder configurations. This makes it a versatile choice for power station projects and cogeneration facilities. Our engineering team can advise on the appropriate circuit breaker and busbar configuration for your generator output requirements.
