The 24th Taiyuan International Coal (Energy) Industry Technology and Equipment Exhibition, themed "Green Intelligence · Innovation and Integration," was recently held at the Shanxi Xiaohe International Convention and Exhibition Center. CEEG made a prominent appearance at the event, unveiling its latest generation of mining flameproof mobile substations to widespread attention from industry experts and clients.
As the largest industry event in China's coal and energy sector, the exhibition brought together over 1,300 domestic and international exhibitors, showcasing cutting-edge technologies, equipment, and processes across the coal and energy industries.
Since anchoring its focus on the specialized track of mining electrical equipment in 2001, CEEG has consistently positioned itself as a pioneer in the field of mining energy equipment. The new-generation mining flameproof mobile substation on display at this exhibition represents multiple breakthroughs in safety, thermal management, insulation, and intelligent monitoring — all engineered to address the complex and demanding conditions of underground mining environments.
Many visitors personally opened the high- and low-voltage switchgear panels to closely inspect the internal structure and components, offering high praise for the product's craftsmanship and reliability.
Key Advantages of CEEG's Mining Flameproof Mobile Substation:
1. Flameproof Safety and Reliability
The flameproof enclosure is rated to withstand pressures of up to 1 MPa, making it suitable for environments where methane and coal dust explosions are a risk. An arched corrugated panel on the top of the unit prevents coal dust accumulation, thereby reducing the risk of ignition.
2. Active Thermal Management — Eliminating Heat Dissipation Bottlenecks
Equipped with a patented multi-circuit active cooling technology, the system leverages thermal differentials to create a natural "chimney effect" — eliminating the need for cooling fans while improving convective heat dissipation efficiency by over 30%, significantly extending equipment service life.
3. High-Performance Insulation for Reliable Operation
The substation incorporates DuPont Nomex® paper insulation combined with VPI (Vacuum Pressure Impregnation) varnishing technology, delivering outstanding heat resistance, anti-aging properties, maintenance-free operation, reduced energy losses, and low noise levels.
4. Convenient Operation and Intelligent Monitoring
The high-voltage side features a vertical hand-hole port for standing-access operation. An integrated intelligent monitoring terminal enables seamless connection to coal mine supervisory control systems, supporting remote monitoring and full lifecycle asset management.
Drawing on a deep understanding of the unique operating conditions in mining environments, CEEG continues to advance through technological innovation. Backed by extensive technical expertise and rich industry experience, the company remains committed to contributing to safe power supply and intelligent infrastructure development across the mining sector — delivering what CEEG calls its "Power of Innovation."
To date, CEEG's mining-type transformers have been widely deployed at major energy enterprises including China Energy Group, Ningxia Coal Industry, and Pingmei Group. Looking ahead, CEEG will continue to innovate, driving the green and intelligent transformation of the coal industry with safer and more efficient power solutions.
