Integrated ZGS-(Z)F wind power transformer steps up 0.69kV turbine output to 12kV/35kV. Features a rugged, all-in-one design with -45°C tolerance and 0.4m/s² seismic resistance. Ideal for harsh, high-altitude, or coastal wind farm environments.
The ZGS-(Z)F series combined transformer is a highly integrated, specialized power solution engineered specifically for the wind energy sector. It seamlessly combines a high-efficiency step-up transformer, high-voltage current-limiting fuses, load switches, low-voltage switchgear, and advanced auxiliary components into a single, robust enclosure.
Designed as the "heart" of the wind farm’s collection system, it steps up the 0.69kV output from the wind turbine to 12kV or 35kV for efficient grid connection. With its compact structure and energy-saving design, it offers a variety of electrical configurations to meet diverse project requirements globally.
All-in-One Integration: Combines transformation, protection, and switching, reducing site installation time and space requirements.
Optimized for Efficiency: Adopts the latest low-loss design and manufacturing processes to maximize energy yield from wind assets.
Flexible Configurations: Provides multiple grid-connected voltage options and structural programs tailored to specific turbine models.
Rugged Reliability: Specifically engineered to withstand the fluctuating loads and harsh environmental conditions typical of on-shore and off-shore wind farms.
Our ZGS-(Z)F series is designed to maintain peak performance even in extreme climates:
Ambient Temperature: Range from -45°C to +40°C, ensuring stability from frigid highlands to tropical zones.
Altitude: Standard design supports up to 2,000m (Higher altitudes available via customization).
Humidity Tolerance: Daily and monthly average relative humidity ≤ 95%.
Seismic Resistance: Built to withstand horizontal acceleration of 0.4m/s² and vertical acceleration of 0.15m/s².
Installation Tolerance: Maximum installation tilt of ≤ 3°.
Site Environment: Requires locations free from corrosive or flammable gases, significant pollution, or violent mechanical vibrations.

Engineered for Extreme Climates Wind farms are often located in high-altitude or frigid regions. Our ZGS-(Z)F series is built to thrive in temperatures as low as -45°C, featuring specialized seals and weather-resistant coatings that prevent component fatigue in the harshest environments.
Integrated "All-in-One" Design By consolidating the step-up transformer, high-voltage protection, and low-voltage switchgear into a single compact unit, we reduce the footprint by up to 40% compared to traditional modular substations. This significantly lowers land preparation and installation costs.
Optimized for 0.69kV to 35kV Conversion Specifically tuned for the output characteristics of modern wind turbines, our transformers minimize energy loss during the step-up process. This ensures that the maximum amount of generated green energy actually reaches the grid.
Rapid Field Deployment The ZGS-(Z)F series arrives at your site fully assembled and factory-tested. This "Plug-and-Play" capability eliminates complex on-site wiring, reducing commissioning time and allowing your wind farm to begin power generation sooner.
Superior Seismic & Vibration Resistance Wind turbine environments are subject to constant low-frequency vibrations. Our transformers feature reinforced internal bracing and secure component positioning to ensure operational stability and prevent mechanical loosening over a 20-year lifecycle.
Flexible Technical Customization We don't believe in "one size fits all." Whether you need a specific grid-connected voltage, a unique structural layout for tight spaces, or specialized protection for high-corrosion coastal zones, JNCN Power provides tailored engineering solutions to match your exact project specs.
