Wind Turbine Nacelle Dry-Type Transformer SC(B)12 Series 35kV Class 1000~10000kVA

Wind Turbine Nacelle Dry-Type Transformer SC(B)12 Series (35kV Class, 1000~10000kVA)

Product Overview
The nacelle dry-type transformer is a vital component of the wind power system, stepping up the power generated by the wind turbine to the voltage level of the transmission grid. Compact, lightweight and low-maintenance, it is engineered to withstand the harsh nacelle environment at height — low-frequency vibration, humidity, pollution and lightning intrusion. Mounted inside the nacelle, it eliminates long high-current LV cables, reduces line losses, saves ground space at the turbine base and shortens the construction schedule.

Key Features

• Low-frequency vibration resistance: reinforced structural members with swing arms anchored to the nacelle wall, verified by finite-element steady-state simulation;
• CFD-optimized cooling: computational fluid dynamics simulation analyzes airflow paths and guides fan/air-duct design for precise cooling — low temperature rise and long service life;
• High-humidity adaptability: HV tap changers fitted with protective collars greatly increasing creepage distance for humid environments;
• Integrated 400V tap: provides 400V auxiliary supply within the nacelle in one unit;
• Built-in surge arresters: HV-side integrated arresters guard against lightning intrusion;
• Space-saving: installed directly inside the nacelle — no ground-area transformer foundation needed;
• Cable & cost saving: step-up performed at height inside the nacelle — saves large-section LV cable cost, cuts line losses and compresses the construction schedule.
