KBSGZY2-T Mining Flameproof Transformer Substation

CEEG's mining flameproof transformer substation consists of a high voltage vacuum switch or high voltage load switch, a dry type transformer, and a low voltage protection box or low voltage feed switch. It is designed to provide stable power in environments such as mines and tunnels where there is a risk of explosion due to methane mixed gas and coal dust, but no gases or vapors that corrode metals or damage insulation.

Product Features

  • Explosion-Proof & Heat Dissipation: Patented full-wave corrugated cylindrical structure, with no water or dust accumulation on the top, offering excellent heat dissipation and strong explosion-proof performance.


  • Premium Insulation: Utilizes Nomex® insulation paper, providing C-class insulation, flame retardancy, explosion proofing, and recyclability.


  • Sturdy and Reliable: Features an eight-point fastening method, suitable for vertical descent into mines; ensures the iron core remains free of lateral movement under various working conditions.


  • Advanced Technology: Employs VPI (Vacuum Pressure Impregnation) for impregnation and drying, enhancing the insulation performance and mechanical strength of the coils.


  • Strong Adaptation: The elliptical structure of the transformer body results in a shorter height and length, meeting the space requirement of various mining environments.


  • Integrated Design Solution: Powers explosion-proof frequency converters and communicates with them to monitor operating status, manage faults, and integrate control functions.


  • Imported PLC: High and low-voltage switches of the mining mobile substation use imported PLC, boasting high reliability and stability
