Driving Innovation in Mining Power Equipment
Since entering the specialized field of mining electrical equipment in 2001, CEEG has consistently positioned itself as an industry pioneer, continuously advancing technological innovation in mining energy equipment.
At this exhibition, the company presented its new-generation explosion-proof mobile substation, specifically designed to operate reliably in complex underground mining environments.
The product achieves multiple technological breakthroughs in:
Safety
Heat dissipation
Insulation performance
Intelligent monitoring
Many visitors personally operated the high-voltage and low-voltage switches, closely examining the internal structure and component details. The product’s superior craftsmanship and reliable performance received widespread recognition and positive feedback from customers.
Advantages of CEEG Explosion-Proof Mobile Substation for Mining
1. Explosion-Proof Safety and Reliability
The explosion-proof enclosure is capable of withstanding internal pressure up to 1 MPa
making it suitable for hazardous environments involving:
Methane gas
Coal dust
Explosion-prone underground conditions
The top-mounted arc-shaped corrugated plate design prevents coal dust accumulation and significantly reduces ignition risks, ensuring enhanced operational safety.
2. Active Cooling Technology Eliminates Thermal Bottlenecks
The system integrates multi-circuit active cooling patented technology, utilizing temperature differences to create a natural “chimney effect.”
Key benefits include:
No cooling fan required
Over 30% improvement in convection efficiency
Extended equipment service life
Improved operational stability
This innovation addresses one of the most critical technical challenges in underground transformer operation—heat dissipation.
3. High-Performance Insulation for Reliable Operation
The transformer adopts:
DuPont Nomex® insulation paper
VPI (Vacuum Pressure Impregnation) technology
These materials and processes provide:
Excellent thermal resistance
Strong anti-aging performance
Maintenance-free operation
Low losses
Low noise levels
This ensures long-term reliability even under demanding mining conditions.
4. User-Friendly Operation and Intelligent Monitoring
The high-voltage side features a vertical operating handhole, enabling operators to perform switching operations conveniently while standing.
In addition, the substation is equipped with:
Intelligent monitoring terminals
Integration capability with mine monitoring systems
Remote monitoring functions
Full lifecycle asset management
These features support the development of modern intelligent and unmanned mining operations.
