110KV~220KV Power Transformer: High pressure transformer utilizing advanced analysis software and specialized calculation procedures. To ensure peak performance, every component including the core, coil, machine body, lead wire, and oil tank is rigorously designed and tested.
The SSZ11-40000/110 model has successfully passed short-circuit bearing capacity tests and all routine type tests at the National Transformer Quality Supervision and Inspection Center. This product is engineered for stability, economy, reliability, and environmental protection, making it ideal for power plants, substations, and large-scale industrial or petrochemical enterprises.



🚀 Efficient Heat Dissipation: Uses insulating oil as a cooling medium. Heat from the core and winding is removed via natural convection or forced circulation. Corrugated fuel tanks and radiators significantly increase the heat dissipation area, ensuring stable operation under high loads.
⚡ Large Capacity & High Voltage: Capable of handling power distribution from 10kV to 1000kV ultra-high voltage transmission. The oil-paper composite insulation system withstands high electric field strength, suitable for high-power electrical scenarios.
