20kV Class Oil-Immersed Power Transformer

  As a core step-down equipment for medium-voltage power grids, the 20kV Oil-Immersed Power Transformer is a high-reliability power distribution device specially designed for voltage conversion and power transmission in 20kV power systems. It takes high-quality mineral oil as the insulation and cooling medium, combined with scientific structural design and high-performance core materials, ensuring stable and efficient step-down operation, and serving as a key link connecting high-voltage power grids and low-voltage distribution networks. Rated at 20kV voltage level, the transformer adopts a mature and reliable oil-immersed structure, with optional ONAN (Oil Natural Air Natural) and ONAF (Oil Natural Air Forced) cooling modes. It has outstanding advantages such as strong overload capacity, excellent heat dissipation performance, stable operation and strong environmental adaptability, which can adapt to long-term outdoor operation in harsh environments such as high temperature, low temperature, heavy rain and heavy dust. Equipped with complete protection devices, including temperature monitoring, oil level monitoring, leakage alarm and pressure relief devices, it effectively avoids potential safety hazards and ensures the safe and continuous operation of the equipment.
