Two Optional Structure Types for Different Scenarios

• Silent Canopy Type: Equipped with integrated sound insulation cabinet, running noise controlled below 75dB(A). Perfect for urban commercial buildings, hospitals, data centers and residential construction sites with strict noise limits. Custom container silent version is available for remote project centralized power supply.

• Open Frame Type: Optimized heat dissipation design, easy daily maintenance, lower overall cost. Ideal for outdoor mining zones, oilfields, large manufacturing factories without noise control restrictions, supporting 24-hour non-stop full-load operation.

Reliable Power Performance & Wide Application

This YC6T660L-D20 500kVA genset supports switchable 50Hz/60Hz frequency and multiple voltage options (220/380V, 230/400V, 240/415V) to fit global regional grid standards. It can be fitted with ATS automatic transfer panel to realize unattended instant startup within 8 seconds once municipal power fails, protecting critical equipment in data centers, mining machinery and oil extraction facilities.

All units undergo strict standardized QC procedures before delivery, including component incoming inspection, no-load running test, 4-hour continuous full-load endurance test and safety protection system calibration. We provide complete CE, ISO9001 certificates, bilingual operation & maintenance manuals, global spare parts supply and on-site FAT factory inspection service for overseas customers.

Suitable application scenarios: Mining projects, oilfield operation zones, large industrial factories, commercial complex backup power, data center emergency power, remote off-grid construction sites, hospital uninterrupted power supply. We support OEM/ODM customization of fuel tank capacity, control panel brand, anti-dust pre-filter and anti-corrosion coating according to client project working conditions.
