Product Description

Why Choose CEEG Mining Power Transformer?
CEEG proudly operates the world's largest production base for mining flameproof transformers, making us the only Chinese enterprise to seamlessly integrate the design and manufacturing of mining flameproof transformers and switches. Additionally, we are the most comprehensive manufacturer of mining transformers in China, offering a diverse range of products including flameproof mining transformers and flameproof mining substations, specifically engineered for mines with explosive gases. We also provide general-purpose transformers suitable for underground locations containing coal dust and methane but no explosion hazards.

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
