Power Transformers
132 kV and Above Power Transformer with OLTC and Off-Load Tap Changer
This type of transformer is equipped with both on-load tap changers (OLTC) and off-load tap changers, providing flexible voltage regulation under various operating conditions. It is designed for use in substations with system voltages of 132 kV and above. The transformer’s internal electric field, leakage magnetic field, temperature distribution, and electromagnetic forces are precisely calculated and optimized. As a result, the product offers low energy loss, low noise levels, minimal partial discharge, and strong short-circuit resistance, ensuring stable and reliable long-term operation.
132 kV and Above Three-Phase Combined Power Transformer
This type of transformer consists of three independent single-phase transformers connected by conductors through inter-phase conduits. Oil circulates through these inter-phase pipelines. The individual units are assembled on-site to form a complete three-phase transformer. Compared to traditional three-phase transformers, these combined units are easily transportable, making them ideal for locations with limited accessibility.
