Product Description
Explosion-Proof Mining Transformer for Underground Coal Mines Ex Certified
Our explosion-proof mining transformers are engineered specifically for underground safety in hazardous mining environments. These mining flameproof substations are designed for special and harsh environmental conditions with excellent explosion-proof performance and mechanical strength.
Safety & Performance Features
- 220°C insulation class for high-temperature operation
- Flameproof Group IIB, Zone 1, Zone 2 certification
- Fire-proof construction with non-toxic air creation
- Low noise operation and environmentally protected design
- Maintenance-free operation with heat shock resistance
- Superior overload capacity and multiple protective functions
- Protection against overload, short circuit, leakage, leakage lockout, over-voltage, under-voltage and over temperature
Mining operations involve high risks including methane exposure, coal dust, humidity, vibration and confined spaces. Our Explosion-proof Mine Transformers (Exd I / Exd I Mb) are engineered to ensure reliable and safe power distribution in these hazardous underground environments.
Key Features
- Certified MA & Explosion-Proof (Ex) compliance
- Explosion-proof enclosure with robust mechanical protection
- Resistant to humidity, dust, corrosion and vibration
- High reliability and low maintenance for continuous operation
- Suitable for underground conveyors, pumps, lighting & ventilation systems
- Compact structure for narrow mine shafts; mobile and fixed options available
Applications
Coal mines, underground tunnels, pump stations, mining conveyors, and underground power distribution systems.
