Product Basic Introduction of On Load Tap Changer Electric Transformer
The OLTC Power Transformer is an Oil Immersed Power Transformer with model S11, rated at 400kVA, featuring a primary voltage of 10kV and a secondary voltage of 0.4kV. It supports dual-frequency operation (50/60Hz) and adopts an oil-immersed design, leveraging coolant oil for efficient heat dissipation to ensure long-term stable performance. As an electrical transformer, it integrates an On-Load Tap Changer (OLTC) system to dynamically adjust voltage in real-time under load, addressing grid voltage fluctuations. Certified by ISO, SGS, and CE, this Oil Immersed Power Transformer guarantees high safety and reliability, making it ideal for industrial power distribution, substation upgrades, and large-scale energy projects.

Advantages of OLTC Power Transformer vs. Standard Transformers
Advantage 1: Dynamic Voltage Regulation, Enhancing Power Supply Stability
Unlike traditional Electrical Transformers, which require power shutdown for voltage adjustment, the OLTC Power Transformer can automatically or manually adjust the tap changer (OLTC) during load operation, achieving precise voltage control. This avoids equipment damage or power outage risks caused by voltage fluctuations.
Advantage 2: High Efficiency and Energy Saving, Reducing Losses
This product adopts an Oil Immersed Power Transformer design with high-quality silicon steel sheets and low-loss windings, reducing no-load losses by 30% and significantly improving operational efficiency. Compared to regular transformers, its OLTC function minimizes energy waste due to voltage instability, making it more economical over long-term use.
Advantage 3: Adaptability to Complex Grid Environments
As an Oil Immersed Power Transformer, this product features a corrosion-resistant coating and sealed design, ensuring stable operation in extreme climates ranging from -40°C to +50°C. Its OLTC function is particularly suitable for grids with significant voltage fluctuations (e.g., remote areas or industrial settings), guaranteeing continuous power supply and electricity quality.
Advantage 4: Intelligence and Safety Assurance
Equipped with oil temperature sensors, pressure release valves, and intelligent monitoring systems, it provides real-time warnings for abnormalities, preventing faults caused by overload or short circuits. Compared to ordinary transformers, the dual advantages of dynamic regulation capability and oil-immersed structure of the OLTC Power Transformer make it the preferred choice for highly reliable power transmission.
