Y Series – High Voltage Generators

Powered by Yuchai | The Heavy-Duty Asian Titan (900kVA – 3000kVA)

The Enerzip® Y Series High Voltage line utilizes the brute strength of Yuchai Machinery, China’s largest and most experienced independent engine manufacturer. Powered by the advanced YC12VC and YC16VC heavy-duty engine platforms, these units deliver a perfect combination of robust torque, high fuel efficiency, and long-term durability. Enerzip® integrates these engines with premium VPI-insulated alternators and professional switchgear to create High Voltage Generators (3.3kV – 11kV) that serve as the preferred workhorses for mining, manufacturing, and real estate projects demanding premium reliability without the premium price of Western brands.

1. The Power Core: Yuchai Heavy-Duty Platform

The heart of the Y Series is the Yuchai V-Type engine (YC12VC / YC16VC), engineered for continuous heavy loads.

• Structural Integrity: Yuchai engines are famous for their high-strength alloy cast iron body and monolithic forged steel crankshaft. This extremely rigid structure reduces vibration and ensures a service life (Time Between Overhauls) that often exceeds 25,000 hours, making them ideal drivers for High Voltage Generators.

• Smart Efficiency: Featuring advanced electronically controlled high-pressure common rail technology and 4-valve cylinder heads, the Y Series optimizes combustion for superior fuel economy, lowering the total Operational Expenditure (OPEX).

• High Torque Performance: Yuchai engines are renowned for their exceptional loading capability and fast response times, making them ideal for starting heavy industrial motors.

2. Starting Systems: Guaranteed Start

• Heavy-Duty Electric Start: We utilize dual 24V electric starting motors to ensure redundancy and rapid cranking speed.

• Cold Weather Performance: Equipped with high-CCA maintenance-free batteries (VARTA/Camel) and integrated coolant heaters. This ensures the engine block remains at the optimal temperature for instant starting, even when ambient temperatures drop below freezing.

• Battery Health: Intelligent floating chargers monitor voltage levels continuously to prevent battery failure during standby.

3. HV Alternator: The Art of Insulation

Generating high voltage requires specialized engineering to prevent electrical breakdown.

• Form-Wound Coils: Our High Voltage Generators utilize alternators from LEROY SOMER, STAMFORD, or ENGGA featuring Form-Wound Coils. Unlike random-wound low-voltage coils, these pre-formed, rigid coils provide superior mechanical strength and thermal endurance.

• VPI Technology: Every stator undergoes Vacuum Pressure Impregnation (VPI). This process forces resin into every crevice of the winding, creating a solid, void-free insulation barrier that is impervious to moisture, dust, and salt spray.

• Anti-Condensation: Heaters are installed to keep the windings dry during standby.

4. Control & Switchgear: Grid-Level Protection

Safety is non-negotiable for high-voltage systems.

• Integrated HV Switchgear: The Y Series includes a professional switchgear cubicle housing a Vacuum Circuit Breaker (VCB) from ABB or Siemens. VCBs are essential for High Voltage Generators as they provide rapid arc quenching and safe fault isolation. For general reference on medium-voltage fault interruption devices, buyers may also review primary vacuum circuit breakers.

• Advanced Logic: Utilizing ComAp (InteliGen) or DEIF controllers, the system offers comprehensive protection (Overcurrent, Earth Fault, Reverse Power) and automatic grid synchronization capabilities.

• Digital Monitoring: Operators can monitor oil pressure, coolant temperature, and electrical parameters remotely via Modbus or Ethernet.

5. Cooling Systems: 50°C Tropical Grade

• Oversized Radiators: We standardize on radiators designed for 50°C ambient temperatures. This ensures the Yuchai engine can deliver its full rated power even in the hottest tropical climates or desert environments.

• Split-Core Design: For larger models (2000kVA+), we often use split-core remote radiators to optimize cooling efficiency for the jacket water and intercooler circuits.

6. Frame & Fuel Tank: Engineered for Stability

• Rigid Base Frame: Manufactured on Enerzip’s robotic welding line, the chassis is reinforced to support the heavy engine and HV alternator without flexing.

• Vibration Isolation: High-efficiency anti-vibration mounts decouple the engine from the frame, protecting the sensitive HV switchgear and ceramic insulators from mechanical stress.

• Fuel Connection: Due to the large capacity, Y Series units typically feature connection points for external bulk fuel tanks, though base tanks are available for smaller models.

7. Containerized Solutions: The “Power House”

For outdoor HV applications, the Y Series is typically deployed in Enerzip® ISO Containers.

• Separate HV Room: The container features a partitioned, air-conditioned room specifically for the HV Switchgear and Control Panel. This ensures operator safety and component longevity by isolating them from engine heat and noise.

• Cable Marshalling: Dedicated high-voltage cable entry boxes facilitate the safe and easy termination of heavy armored cables.

8. Exhaust & Emission: Clean & Quiet

• Acoustic Silencing: We install high-attenuation industrial silencers to bring noise levels down to acceptable standards for industrial zones.

• Clean Combustion: Yuchai’s advanced combustion technology ensures low smoke and compliance with standard industrial emission regulations.

9. Silent Canopy: Weather Defense

• Corrosion Protection: Our enclosures use an advanced multi-stage powder coating process, offering superior durability against UV rays and rain compared to wet paint.

• Sound Attenuation: Lined with high-density acoustic foam, the canopy effectively suppresses mechanical noise.

Power Ratings (kVA)

The Y Series offers a robust range of power outputs:

• Medium-High Range: 900, 1000, 1125, 1250 kVA

• Heavy Duty Range: 1500, 1650, 1875, 2000, 2250 kVA

• Ultra-Large Range: 2500, 2750, 3000 kVA
