12 sets of 1200kW high-voltage diesel generator sets have been delivered to a large coal mine
Case Study: 12 × 1200kW High-Voltage Diesel Generator Sets for a Xinjiang Coal Mine
Recently, our company successfully completed the delivery and commissioning of 12 sets of 1200kW high-voltage diesel generator sets for a major energy group in Xinjiang. These units have been officially put into operation as standby power systems for mine production, providing stable and reliable electricity to critical processes such as underground mining, ventilation, and hoisting.
Project Background
This coal mine is a key provincial energy project in Xinjiang, with an annual production capacity of 15 million tons. Its operations impose exceptionally high demands on power continuity— any interruption to underground ventilation, drainage, or lifting equipment would directly compromise both production safety and efficiency. After multiple rounds of site inspections, technical evaluations, and competitive bidding, the client selected our high-voltage diesel generator sets as the optimal solution.
Core Product Advantages
- Robust Powertrain Configuration: Powered by the Weichai WP13 series engine coupled with a Stamford brushless generator. Each unit delivers a rated output of 1200kW at 10kV, enabling direct integration into the mine’s high-voltage distribution network and eliminating the need for intermediate transformers.
- Intelligent Control & Rapid Response: Equipped with an advanced PLC control system compatible with the mine’s existing automation platform. The system enables automatic startup within 0.8 seconds of a grid failure, ensuring seamless load transfer and uninterrupted operation of critical equipment.
- Environmental Compliance & Cold-Climate Adaptability: Fully compliant with China’s National IV emission standards for non-road mobile machinery and fitted with a high-efficiency exhaust after-treatment system. The units are engineered for stable starting at temperatures as low as −30°C, meeting Xinjiang’s stringent environmental and climatic requirements.
End-to-End Project Execution
To ensure flawless execution, we established a dedicated project service team:
- Pre-Sales Engineering: Our technical team conducted multiple site visits to evaluate underground load profiles, installation constraints, and local climate conditions, delivering a customized layout and startup strategy tailored to the mine’s operational reality.
- Manufacturing Excellence: Production strictly adhered to the ISO 9001 quality management system. All key components underwent three consecutive rounds of full-load endurance testing to guarantee long-term reliability.
- Rapid On-Site Commissioning: Six senior engineers were stationed on-site throughout the delivery phase, completing installation, electrical wiring, commissioning, and operator training for all 12 units within just seven days—fully aligned with the client’s requirement to “meet the deadline and secure production.”
Customer Validation

Since commissioning, the generator sets have successfully responded to two utility grid disturbances, achieving zero-fault transfer on both occasions. This capability has effectively prevented production losses caused by power interruptions and established a robust “power defense line” for safe mining operations.
Strategic Significance
This project represents another benchmark achievement for our company in the mining and energy sector, demonstrating our integrated strength in the R&D, manufacturing, and lifecycle servicing of high-voltage, high-power diesel generator sets. Looking ahead, we remain committed to addressing the evolving needs of the energy industry—advancing intelligent power generation technologies and delivering more reliable, efficient, and environmentally responsible backup power solutions for mines, oilfields, data centers, and industrial facilities worldwide.
