KBSG9-50~1600/10 Mining Flameproof Dry Type Transformer

The KBSG9 series mining flameproof dry-type transformer is designed for underground environments with methane gas, coal dust, and explosion hazards. It features a high-strength structure, low temperature rise, and excellent heat dissipation. The transformer is moisture-resistant and requires minimal maintenance. It operates reliably at altitudes up to 1000m, with ambient temperatures ranging from -5°C to +40°C. It can withstand relative humidity up to 95% at 25°C. The installation site must be free from severe vibration, and the inclination angle should not exceed 15 degrees.
