HM Power, a premier ASNA Ring Main Unit manufacturer, 

In China's industrial policy framework, the designation of "National Little Giant" enterprise carries a specific and demanding meaning. The ...

Italy has witnessed rapid growth in installed capacity of wind and solar new energy, with steadily rising demand for energy storage on both grid-side and commercial & industrial sides. By charging and discharging to implement peak shaving and valley filling, energy storage systems effectively smooth grid fluctuations and reduce power consumption costs. As a critical component for grid connection, the medium-voltage switchgear supporting energy storage power stations is subject to growing attention on environmental compliance. Relevant EU greenhouse gas control regulations impose mandatory constraints on equipment selection. The EU F-Gas Regulation (EU) 2024/573 clearly stipulates that SF₆ greenhouse gas shall be prohibited for new medium-voltage switchgear with rated voltage ≤24kV starting from 1 January 2026.

The Tanzania Sapphire Float Glass Industrial Park is a benchmark project under China’s Belt and Road Initiative. The glass manufacturing process imposes extremely stringent requirements on power supply continuity, power quality and voltage stability. Meanwhile, the park features complex operating conditions including high temperature, high humidity, dust and tin fog corrosion, which pose severe challenges to the corrosion resistance and long-term operational reliability of power distribution equipment.

Stockholm, Sweden, is a benchmark for smart city and green low-carbon urban development in Northern Europe. It was awarded the world’s first "European Green Capital" title in 2010. As a key supporting initiative for the grid intelligence and urban low-carbon transition of Stockholm, this smart city power distribution project comprehensively improves the stability and environmental performance of urban public power supply and serves as an important pillar for long-term sustainable development.

In 2014, the first batch of Tesla Superchargers in Västerås, Sweden, supporting this project was completed and put into operation. It serves as a highly representative energy replenishment infrastructure for new energy vehicles in Northern Europe. As a high-power dynamic electrical load scenario, the supercharger station imposes stringent requirements on the 10kV distribution system in terms of power supply reliability, equipment stability, fault handling capability and low-carbon compliance.

The commercial Wenchang Space Launch Site is located on the coast of Hainan, featuring year-round high humidity and salt spray. Its core power distribution room supports uninterrupted critical services including launch telemetry & control, command communication and data computation. It imposes aerospace-grade stringent requirements far exceeding ordinary industrial standards on the safety level of the power distribution system, power supply continuity, environmental weather resistance and long-period maintenance-free performance.

As the core aviation hub of the Hainan Free Trade Port, Haikou Meilan International Airport undertakes key functions including passenger and cargo transportation as well as air traffic control (ATC) navigation support. The ATC station room renovation required an upgrade of the power distribution system under non-stop flight and uninterrupted ATC service conditions. The project demands absolutely continuous and secure power supply, while the equipment must adapt to on-site conditions featuring densely arranged devices and complex electromagnetic environments.

Tencent Data Center in Guizhou is China’s first large-scale cave-type data center, undertaking core services including data storage and AI training. Power outages may result in data loss and computing capacity loss, so extremely high reliability requirements are imposed on power supply. Its unique geographic location also raises stringent requirements for anti-condensation performance and maintenance-free operation.
