W Series – High Voltage Generators

Powered by Weichai (Baudouin Tech) | Massive Power, Maximum Value (900kVA – 3750kVA)

The Enerzip® W Series High Voltage line shatters the barrier to entry for large-scale industrial power. Powered by Weichai® heavy-duty engines (incorporating French Moteurs Baudouin technology), these units offer the highest power density and best price-per-kVA in the global market. Enerzip® integrates these massive engines with professional high-voltage switchgear to create High Voltage Generators (3.3kV – 11kV) capable of delivering up to 3750kVA. This series is the “ROI Champion” for mining sites, big data campuses, and grid peaking stations that demand massive output without the premium price tag.

1. The Power Core: Weichai (Baudouin DNA)

The heart of the W Series is the Weichai heavy-duty engine platform (Series 12M33, 16M33, and the massive M55 series).

• European Technology Roots: These engines are built on the technology license of Moteurs Baudouin (France). They feature a rigid cast-iron gantry block construction, ensuring high structural strength and low vibration—critical for the longevity of High Voltage Generators.

• Massive Power Density: The W Series delivers incredible power from a compact footprint. The 20M55 engine, for example, pushes power limits to compete with the largest global brands, allowing for fewer units to be installed for the same total plant capacity.

• Advanced Common Rail: Equipped with high-pressure common rail fuel systems, these engines offer precise combustion control, resulting in excellent load acceptance and fuel efficiency.

2. Starting Systems: Heavy-Duty Ignition

Starting a 3000kVA engine requires immense torque.

• Air/Electric Starting: Standard configuration includes dual 24V electric starting motors. For specific oil & gas applications, air starting systems are available upon request.

• Cold Start Capability: High-capacity maintenance-free batteries (VARTA/Camel) provide massive Cold Cranking Amps (CCA). Integrated coolant heaters ensure the engine block remains warm, guaranteeing ignition even in sub-zero environments.

• Battery Maintenance: Intelligent floating chargers are installed as standard to ensure batteries are fully charged and ready for standby duty.

3. HV Alternator: Specialized Insulation

Generating high voltage at these power levels requires robust engineering.

• Form-Wound Coils: Our High Voltage Generators utilize alternators from LEROY SOMER, STAMFORD, or ENGGA featuring Form-Wound Coils. These pre-shaped, rigid coils offer superior mechanical strength against the magnetic forces generated during short circuits.

• VPI Technology: Every stator undergoes Vacuum Pressure Impregnation (VPI). This process eliminates air voids, creating a solid insulation barrier that prevents corona discharge and resists moisture and dust contamination.

• Bearing Protection: Insulated non-drive end bearings are standard to prevent circulating shaft currents.

4. Control & Switchgear: Professional Output Protection

Safety is paramount when handling 10.5kV at 3000+ kVA.

• Vacuum Circuit Breaker (VCB): The W Series includes a dedicated switchgear cubicle housing a Vacuum Circuit Breaker (VCB) from ABB or Siemens. VCBs provide rapid arc quenching, essential for protecting expensive High Voltage Generators during fault conditions.

• Smart Management: Utilizing ComAp (InteliGen) or DEIF controllers, the system provides comprehensive monitoring (oil pressure, temp, speed) and full ANSI-coded electrical protection (50/51, 51G, 32, etc.).

• Grid Synchronization: Automatic synchronization allows multiple W Series units to parallel together to create a 20MW+ power station easily.

5. Cooling Systems: 50°C Industrial Grade

Weichai engines are high-performance machines that require effective heat dissipation.

• Split-Core Radiators: For the largest models (M55 series), we utilize horizontal or vertical remote radiators with separate circuits for jacket water and low-temperature aftercooling (LTAC).

• Tropical Rating: All cooling systems are sized for 50°C ambient temperatures, ensuring the generator can run at full continuous rating in hot mining or desert environments without overheating.

6. Frame & Fuel Tank: Built for Stability

• Structural Rigidity: Manufactured on Enerzip’s robotic welding line, the chassis is built from heavy-gauge I-beams to support the massive weight of the 20-cylinder engine and HV alternator.

• Vibration Isolation: High-efficiency spring isolators decouple the genset from the frame, preventing vibration transmission to the foundation and the sensitive HV switchgear.

• Fuel Systems: Due to the high fuel consumption of these large units, we typically supply external bulk fuel tank connections rather than integral base tanks.

7. Containerized Solutions: The Mobile Power Plant

For models above 1250kVA, containerization is the standard deployment method.

• 40ft High Cube: Our High Voltage Generators are housed in custom-modified 40ft ISO High Cube containers. These “Power Houses” feature sound attenuation, motorized louvers, and fire suppression systems.

• Separate HV Room: A partitioned, air-conditioned room houses the HV Switchgear and Control Panel, isolating operators from the noise and heat of the engine room.

8. Exhaust & Emission: Compliance & Silence

• Industrial Silencers: Massive industrial-grade silencers are mounted on the container roof or internally to reduce noise levels.

• Emission Control: Weichai engines utilize advanced internal combustion technology to meet standard industrial emission regulations. SCR after-treatment systems are available for stricter regions.

9. Enclosure & Finish: Durability

• Anti-Corrosion: Containers are painted with marine-grade paint systems to resist salt spray and rust.

• Sound Proofing: Internal walls are lined with high-density rock wool and perforated galvanized steel sheets to maximize sound absorption and durability.
