Key Specifications

Core Advantages

✅ Large Displacement 6-Cylinder Turbocharged Intercooled Engine: G128 series STF heavy-duty engine with 13.7~14.4L displacement, turbocharged intercooled design. It has massive torque reserve to handle sudden heavy load surges, maintaining stable performance during long continuous heavy-duty operation. ✅ TZH Brushless Self-Excited All-Copper Alternator: Brushless structure eliminates carbon brush wear and frequent maintenance work. Pure copper coil with AVR automatic voltage regulator ensures stable voltage output even under variable heavy load conditions.

✅ Precision Electronic Speed Governing System: Electronic governor delivers fast, precise speed adjustment. It rapidly responds to load changes and reduces speed fluctuation, protecting expensive industrial electrical equipment against unstable power supply.

✅ High Efficiency Heavy-duty Water Cooling System: Large-size water radiator supports continuous running under ambient temperature up to 40℃, effectively preventing overheating faults during long-hour heavy load operation.

✅ IP23 Protection & Class F Insulation: Class F winding insulation improves high temperature resistance; IP23 grade blocks solid particles and splashing water, adapting to complex industrial and semi-outdoor working environments.

🎯 Application Scenarios

Large manufacturing plant continuous power, mining site main power supply, industrial park standby power, large sewage treatment station, large construction infrastructure, commercial complex emergency backup, remote area power supply. Optimized for long-duration heavy-load operation.

⚙️ Optional & Customization
