Focus on "Environmental Adaptability" – Engineered for Extreme
Underground Conditions
The Critical Challenge: How Harsh is the Underground Environment?
We Fully Adapt
Underground mining is not a standard electrical environment. It is
a hostile domain characterized by methane accumulation, pervasive
coal dust, high humidity (≤95% @25℃) , and constant vibration
(vertical inclination ≤15°) . In these conditions, standard
transformers are prone to corrosion, mechanical loosening, and
catastrophic failure.
The HENTG POWER KBSG Series Mining Explosion-Proof Dry-Type
Transformer is engineered with "Environmental Adaptability" as its
core design philosophy. From material selection to structural
integrity, it is fully tailored to meet underground demands,
ensuring power supply equipment maintains unwavering stability in
high-risk 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)


Core Advantages: Fearless in Harsh Conditions, Durable, and
Resilient1. Confronting Explosion Risks: Adapted for Flammable Gas & Dust
• Targeting the hazards of methane and coal dust explosions, this
product has achieved Exd I / Exd I Mb explosion-proof certification
and fully complies with the GB 3836 "Electrical Equipment for
Explosive Atmospheres" standard. It can be deployed directly in
Class I explosive hazard areas within underground coal mines,
eliminating the risk of ignition via electric sparks. • Versatile
Application: Suitable for Zone 1 and Zone 2 explosive dust areas,
ensuring safe operation in both coal mining faces and metal mine
crushing roadways.
2. Withstanding Severe Climates: Moisture-Proof,
Corrosion-Resistant, Vibration-Proof
• High Protection Rating (IP54-IP65): The fully sealed structure
effectively blocks coal dust intrusion, while the 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: The shell features a mining-specific anti-corrosion paint
that resists erosion from acidic/alkaline gases, significantly
extending the equipment's service life. • Vibration-Resistant
Structure: The iron core assembly is secured with channel steel
clamps and tension screws, while a specialized coil compression
device prevents loosening. It withstands underground mechanical
vibrations (vertical inclination ≤15°), preventing failures caused
by component displacement.
3. Adapting to Complex Conditions: Temperature & Altitude
Compatibility
• Wide Temperature Operation: Tolerates ambient temperatures from
-20℃ to +40℃, with internal insulation materials capable of with
standing temperatures exceeding 135℃. It will not succumb to
overheating, even in local high-temperature zones (e.g., near heavy
mining machinery). • Low-Altitude Adaptation: Supports operation in
mining areas at altitudes ≤2000 meters without parameter
adjustments. It maintains stable output even in plateau mining
regions such as those in Mongolia and South Africa.
4. Diverse Scenario Application: From Coal Mines to Tunnels
• 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.
