The highly anticipated 9th Harbin 2025 Asian Winter Games has come to a successful conclusion. The GIS-66kV intelligent substation equipment independently developed by the switch company has built a power defense line, interpreting the mission and responsibility of Chinese power equipment enterprises, and writing a new chapter in serving international competitions in extreme cold.
As the core power supply unit of the Asian Winter Games, the switch company resolutely implemented General Secretary Xi Jinping's concept of "green, shared, open, and clean" games, and fully implemented the requirements of "simple, safe, and exciting". After receiving the power supply task, the company immediately selected business backbones to form a commando team, led by Wang Jinze, a "technical pioneer" of after-sales service, to rush to Harbin overnight. This team gave up the Spring Festival holiday for family reunion and stationed at key positions in the Asian Winter Games competition area at minus 30 degrees Celsius. They worked continuously for 40 days and nights, contributing important forces to the Asian Winter Games of "Ice and Snow Dreams, Asian Hearts", and fully demonstrated the style and spirit of the iron army that dares to fight hard battles and can win battles.
Facing the challenge of the extreme cold of -20℃ on the banks of the Songhua River, the switchgear uses the independently developed SF6/N2 mixed gas insulation system. In the Yabuli Ski Resort, even in the ultra-low temperature of -30℃, the circuit breaker opening and closing time error is still controlled within 0.02ms. Its unique "extreme cold adaptive temperature control system" adjusts the equipment temperature environment in real time through embedded sensors, successfully solving the industry problems of mechanism jamming and gas liquefaction that are prone to occur in traditional GIS equipment at low temperatures.
In the Asian Winter Games area, the switch company has built a power service system covering the entire life cycle, and with the hard-core service capabilities of "zero time difference response + full chain escort", it has fulfilled the solemn promise of "no power outage during the event and zero equipment defects". At the same time, it also demonstrated the outstanding and superb business capabilities and dedicated professionalism of the switch service engineers.
