Voltage Options & Circuit Protection
Factory Configuration: Native 400V/230V, 3-phase, 50Hz output designed for European, Asian, and African grid compatibility.
Adjustable Terminals: Field-reconfigurable busbars support 380V, 415V, and 440V distribution systems.
Voltage Regulation: Automatic Voltage Regulator (AVR) maintains steady-state voltage within ±1.0% across 0–100% load variations.
Power Quality: Total Harmonic Distortion (THD) remains under 5%, preventing waveform distortion on sensitive PLC and VFD controls.
Circuit Protection: Main circuit breaker withstands 300% rated short-circuit current for 10 seconds and tolerates 25% phase load imbalance.
Trailer Mobility & Towing Safety
Chassis & Speed:
Heavy-duty dual-axle channel-steel chassis designed for off-road and highway transport at speeds of up to 60 km/h (37 mph).
Braking System:
Mechanical inertia overrun brake paired with an independent manual parking brake for site security.
Towing Hitch:
Height-adjustable drawbar with interchangeable ring eye and ball couplers for varied towing vehicles.
Running Gear:
Leaf spring suspension, four mechanical drop-down leveling jacks, and an integrated 24V LED tail light bar.

Cooling Performance
High-Ambient Radiator: 50°C heavy-duty radiator prevents engine thermal derating under direct sunlight and high ambient heat.
Cold-Start System: Factory pre-filled with -25°C anti-corrosion coolant and equipped with a 220V jacket water heater.
Coolant Monitoring: Top-tank sight glass enables instant visual checks; an electronic sensor triggers automatic low-coolant shutdown.
Oil Thermal Control: Dual wax-element thermostats maintain engine lube oil within optimum operating viscosity.
Maintenance
Access Layout: Lockable dual side doors with 180° swing hinges provide direct access to oil filters, belts, and the alternator.
Service Schedule: Initial break-in inspection at 50 operating hours; standard lube oil and filter replacement every 250 to 500 hours.
Clean Fluid Drainage: External oil and coolant drain lines extend outside the frame rails with manual shutoff valves.
Visual Inspection: A transparent fuel-water separator bowl and a dry-type air-filter differential-pressure indicator enable quick routine inspections.
Packaging & Delivery
Minimum Order: Minimum Order Quantity (MOQ) is 1 unit for evaluation, fleet sampling, or project bids.
Lead Times: Standard 400V/50Hz units ship within 20-35 days; customized configurations ship in 15 to 20 business days.
Export Packaging: Shrink-wrapped with heavy-duty UV protective film and corner guards, sized for 20ft GP and 40ft HQ containers.
Logistics & Documentation: FOB Tianjin/Qingdao or CIF shipping terms, complete with Commercial Invoice, Packing List, Bill of Lading, Certificate of Origin, and Marine Insurance.
FAQ
Q:What is the noise level of this trailer generator, and does it include a sound-attenuated canopy?
A: Yes, the standard canopy is rated at 72 dBA at 7 meters under full load; trailer-mounted units run slightly louder than stationary silent models.
Q: Can spare parts be supplied after the generator is delivered?
A: Yes, commonly required service parts such as filters, belts, sensors, and electrical components can be supplied separately.
Q: Which engine brand powers the standard 250 kVA trailer generator?
A: The standard configuration uses a Cummins or Perkins turbocharged diesel engine as the default selection, with alternative brands available on request.
Q: What is the warranty period for this generator set?
A: The standard factory warranty covers the engine, alternator, and control system for 12 months or 2,000 operating hours, whichever comes first.
Q: What is the fuel tank capacity?
A: The standard base tank holds approximately 400 liters, providing roughly 10-12 hours of continuous runtime at 75% load before refueling is required.
