Tenrony's KYN28-12 High-Voltage Switchgear Successfully installed and stable operation well in national 5A-level Baiyun Forest Park

The KYN28-12High-voltage metal-enclosed switchgear series has been successfully installed and is operating stably in the eastern area of the 5A-level national tourist attraction, Baiyun Mountain Forest Park. It effectively guarantees the safe power supply of the eastern area of the scenic spot, meets the high-load power demand, and provides continuous and reliable power support for tourist service facilities and management operations, the intelligent monitoring system equipment can monitor load changes in real time, precisely control power distribution, and significantly shorten the response to faults. During peak power consumption periods, the switchgear has excellent heat dissipation performance, and stable power supply. Maintenance personal have reported that no power interruption events have occurred since the equipment was put into operation, significantly enhancing the power service guarantee capacity of the scenic area and providing strong support for the integrated development of smart tourism and green energy. Especially in extreme weather conditions such as thunderstorms and humidity, this switchgear demonstrates outstanding environment adaptability, effectively resisting external environmental interference and ensuring the stable operation of the system. It's modular structure design facilitates later maintenance and upgrades, reduces the risk of downtime, and extends the overall service life of the equipment.

This equipment has passed all type tests at the National High Voltage Electrical Appliance Quality Supervision and Inspection Center, with all performance indicators meeting standard requirements. It is equipped with a complete “five-prevention” interlock function to prevent misoperation, effectively ensuring the safety of operation. On November 3, 2025, the power supply management department of the scenic area organized a special inspection. The results showed that the main circuit resistance, insulation performance, and relay protection action accuracy of the switchgear were all superior to national standards, providing a replicable and verifiable demonstration case for its promotion and application in complex mountainous environments. This inspection focused on evaluating the anti-corrosion performance of the equipment under long-term high humidity conditions. The test results indicated that the coating on the cabinet was intact and there was no oxidation of the internal components,fully verifying the effectiveness of the protective design adopted for the rainy climate in the south.

Combined with real-time monitoring data, the average mean time between failures of this batch of switchgear has exceeded 12000hours, reaching the leading level among domestic similar products.

This application case provides important technical references for the selection and configuration of power equipment in high-altitude and high-humidity areas, promoting the standardization process of high-voltage switchgear construction in complex natural environments, this practice not only demonstrates the high reliability of domestic high-voltage switchgear under extreme conditions but also reveals a profound proposition: the resilience level of infrastructure directly determines the boundaries of modern pubic service capabilities.
