Environmental Adaptability for Extreme Underground Conditions
Underground mining presents hostile conditions including methane accumulation, pervasive coal dust, high humidity (≤95% at 25℃), and constant vibration (vertical inclination ≤15°). Standard transformers are vulnerable to corrosion, mechanical loosening, and catastrophic failure in these environments.
The HENTG POWER KBSG Series Mining Explosion-Proof Dry-Type Transformer is engineered with environmental adaptability as its core design principle. From material selection to structural integrity, it is fully optimized for underground demands, ensuring unwavering stability in high-risk mining environments.
Key Environmental Adaptability Parameters
- Explosion-Proof Grade: Exd I / Exd I Mb
- Humidity Resistance: Relative humidity ≤95% (at 25℃)
- Vibration Adaptation: Vertical inclination ≤15°, anti-loosening structure
- Temperature Adaptation: Ambient -20℃ to +40℃; Insulation resistance ≥135℃
- Protection Rating: IP54-IP65 (Dustproof and Waterproof)
Confronting Explosion Risks: Adapted for Flammable Gas & Dust
Designed to address methane and coal dust explosion hazards, this product achieves Exd I / Exd I Mb explosion-proof certification and fully complies with GB 3836 "Electrical Equipment for Explosive Atmospheres" standards. It can be deployed directly in Class I explosive hazard areas within underground coal mines, eliminating ignition risks from electric sparks.
Versatile application suitability includes Zone 1 and Zone 2 explosive dust areas, ensuring safe operation in both coal mining faces and metal mine crushing roadways.
Withstanding Severe Climates: Moisture-Proof, Corrosion-Resistant, Vibration-Proof
High protection rating (IP54-IP65) features fully sealed construction that effectively blocks coal dust intrusion, while waterproof design handles underground water spraying scenarios. Even in prolonged high-humidity environments, internal components remain protected against moisture and corrosion.
Specialized anti-corrosion coating on the shell resists erosion from acidic/alkaline gases, significantly extending equipment service life. Vibration-resistant structure includes iron core assembly secured with channel steel clamps and tension screws, plus specialized coil compression devices to prevent loosening. The design withstands underground mechanical vibrations (vertical inclination ≤15°), preventing failures from component displacement.
Adapting to Complex Conditions: Temperature & Altitude Compatibility
Wide temperature operation tolerates ambient temperatures from -20℃ to +40℃, with internal insulation materials capable of withstanding temperatures exceeding 135℃. The transformer maintains performance even in local high-temperature zones near heavy mining machinery.
Low-altitude adaptation supports operation in mining areas at altitudes ≤2000 meters without parameter adjustments, maintaining stable output even in plateau mining regions such as Mongolia and South Africa.
Diverse Scenario Applications
- Underground Coal Mines: Powers mining faces, ventilation systems, drainage pump stations, and hoist support
- Metal/Non-Coal Mines: Supplies power for roadway lighting, crushing equipment, and electric traction machinery
- Tunnel Projects: Supports tunnel construction ventilation, drainage, and temporary lighting systems
