Application

As the world accelerates toward renewable energy, wind power has become a cornerstone of sustainable electricity generation. However, wind farms present unique challenges: fluctuating output, harsh environmental conditions, and the need for high efficiency over decades of operation. At Shandong Kerui Transformer Co., Ltd. , we provide robust, high-performance transformer solutions specifically engineered for wind power applications.

Why Wind Power Needs Specialized Transformers
Wind turbines generate electricity at variable voltages and frequencies. Transformers are essential to step up the voltage from the turbine (typically 690V or 35KV) to the grid level (110KV, 220KV or higher). The transformers used in wind farms must withstand extreme weather, temperature swings, humidity, salt spray (offshore), and continuous load variations.

Our Transformer Products for Wind Farms

1. Oil-Immersed Transformers (220KV, 110KV, 35KV and below)
   – Ideal for onshore wind farm collector substations.
   – High overload capacity and excellent cooling performance.
   – Available in S20 (Level 2) and S22 (Level 1) energy efficiency series.

2. Dry-Type Transformers (SCB series, SGB series)
   – Perfect for offshore wind platforms or fire-sensitive areas.
   – Non-encapsulated SGB series with Class H insulation offers superior safety.
   – SCB epoxy resin cast type provides moisture and pollution resistance.

3. American-style & European-style Box Substations
   – Compact, pre-assembled units for wind turbine step-up applications.
   – Reduce installation time and civil works.
   – Weatherproof enclosures suitable for coastal or desert wind farms.

Key Advantages of Kerui Transformers for Wind Power

• High Reliability: Designed for 24/7 continuous operation with minimal maintenance.

• Energy Efficiency: Our Level 1 (S22, SCB18) and Level 2 (S20, SCB14) transformers reduce no-load losses, maximizing wind farm ROI.

• Customizable Voltage Levels: From 6KV, 10KV, 35KV up to 110KV and 220KV.

• Robust Construction: Anti-corrosion treatment, sealed structures for dusty or salty environments.

• Global Compliance: Meet IEC and other international standards for export to Southeast Asia, West Asia, Arab regions, and beyond.

Case in Point
In a recent onshore wind project in the Middle East (high temperature, sandy conditions), our 35KV oil-immersed amorphous alloy transformers achieved over 99% operational availability, significantly lowering the customer’s lifecycle cost.
