Weifang 75kW Diesel Generator Set

The 75kW / 93.75 kVA generator unit is driven by an industrial Weifang multi-cylinder turbocharged diesel engine designed for prime power generation in accordance with ISO 8528 Class G2. Equipped with an in-line high-pressure mechanical injection pump and high-inertia flywheel, the engine provides high low-speed torque rise, absorbing sudden block-load applications up to 55%–60% of rated capacity with transient frequency deviation under 8% and recovery under 3.5 seconds. Under standard 400V/50Hz operation, fuel consumption rates are approximately 10.5 L/h at 50% load, 15.2 L/h at 75% load, and 20.0 L/h at 100% prime load (BSFC 215–225 g/kW·h). The integrated base chassis includes a heavy-gauge steel day tank providing over 10 hours of continuous runtime, complete with visual level indicators and dual-stage spin-on fuel filtration.

Operating at 400V/230V 3-phase, the 75kW unit produces a continuous line current of approximately 135 Amperes. Line distribution is protected by a factory-fitted 160A (or optional 200A) 3-pole thermal-magnetic Molded Case Circuit Breaker (MCCB) with adjustable overload and short-circuit trip mechanisms. For harsh outdoor environments, the soundproof enclosure is fabricated from electro-galvanized cold-rolled steel with outdoor-grade polyester powder coating, resisting salt spray and UV degradation while damping noise to 70–73 dB(A) at 7 meters via perforated zinc-coated lining and rock wool slabs. Electrical monitoring is managed by a SmartGen or Deep Sea micro-processor controller with built-in RS485 Modbus connectivity and dedicated dry-contact terminals for seamless coupling to an external Automatic Transfer Switch (ATS) cabinet.
