Product features

Engineered for site conditions, not for the showroom

Heavy-Duty Open Frame Construction

Open construction on a steel base frame means the 300 kW set exposes every service point — no panels to remove before inspection or maintenance.

300 kW Prime / 330 kW Standby Duty

At 380/220 V, 50 Hz and 1500 rpm the set delivers 300 kW prime / 330 kW standby, 375 kVA. It is specified for continuous prime duty with regular load swings.

Tier-1 Diesel Engine Platforms

Diesel engine platform choices for this 300 kW set are Cummins, Perkins, Weichai and Yuchai; the platform for your order is confirmed at order stage after alternator matching.

Closed Water-Cooling with Forced Fan

For the 300 kW rating, cooling is closed water-circuit with forced ventilation; the oversized tank absorbs heat soak during long continuous operation.

Industrial Protection and Environmental Adaptability

Protection on the 300 kW unit is IP23 or higher by sealing and anti-corrosion finishing, upgradable where dust, rain, snow or heat are more severe.

Flexible Configuration and Fast Deployment

Site wiring and start-up on the 300 kW set can be shortened with an optional ATS, remote monitoring, cable winch and quick connectors; the remaining settings follow the project specification.

Applications

Where this 300 kW open frame diesel generator set is used

1. Production lines The 300 kW set is commonly applied to production lines and compressors at continuous prime duty with regular load swings. Mixed motor and lighting load means the alternator is matched with step-load margin at 300 kW.

2. Hotels For hotels and commercial buildings the 300 kW rating covers mid-size industrial and site power at continuous prime duty with regular load swings. Shift patterns for the 300 kW set usually mean 12–16 hours a day, so fuel autonomy is calculated on that basis.

3. Data Where data and telecom rooms is the load, the 300 kW rating is normally specified at continuous prime duty with regular load swings. Compressor and motor starts drive the transient requirement, which is checked against the 300 kW rating.

4. Quarries The 300 kW open frame diesel generator set set suits quarries and crushing plants. Duty is continuous prime duty with regular load swings. Parallel operation on the 300 kW set is often considered where duty is split between two units.

5. Agricultural processing Agricultural processing is a standard application for the 300 kW unit, which runs at continuous prime duty with regular load swings. Sound limits at the boundary usually point to a canopy build at the 300 kW rating.

6. Site offices The 300 kW set is commonly applied to site offices and welfare blocks at continuous prime duty with regular load swings. Cable runs for the 300 kW set are longer, so voltage drop is checked before the final rating is fixed.

FAQ

Frequently asked questions about this 300 kW open frame diesel generator set

What power rating does this generator set provide?

This unit is rated 300 kW prime / 330 kW standby (375 kVA) at 380/220 V, 50 Hz, 1500 rpm. Rated current is stated on the approved data sheet for the selected build, because it follows the voltage and power factor confirmed for the project.

Which diesel engines are available for this set?

This 300 kW set is available on Cummins, Perkins, Weichai and Yuchai platforms. The engine is matched to the alternator at the 300 kW rating and the complete set is aligned and full-load tested in our own works, so the platform for your order is confirmed at specification stage rather than assumed.

Open Frame, silent or containerized — how do I choose?

Enclosure choice follows site conditions rather than rating. This page covers the open frame set build; at 300 kW the same engine and alternator package can also be supplied in the other builds across Outevo’s 10–3,750 kVA range, with parallel operation is available where duty is split across two units.

Can the voltage and frequency be customised?

Yes. 380/220 V and 50 Hz are the published standard for the 300 kW rating, but voltage and frequency are set to your project specification under OEM/ODM terms, including 60 Hz and medium-voltage requirements where the project calls for them.

What is the minimum order quantity?

One set. A single 300 kW unit can be ordered for a standalone site; where load growth or redundancy is expected, parallel operation is available where duty is split across two units. Other ratings in the 10–3,750 kVA range are quoted per project.

How is the quality of each unit assured?

Every 300 kW set is assembled and load-tested on our own production lines before shipment, and travels with a data sheet and test record. Shanghai Outevo Machinery Co., Ltd. has manufactured diesel and gas sets including this 300 kW rating generator sets since 2006 from a 20,000 m² production base in Shandong.
