220kV Oil-immersed Power Transformers

Product Introduction

The 220kV oil immersed Power Transformer is made of high-quality cold-rolled silicon steel sheets to create the iron core, combined with advanced winding technology. The no-load and load losses are extremely low, and the energy efficiency far exceeds the national standard. The fully sealed fuel tank design isolates air and moisture, significantly delaying insulation aging and ensuring long-term stable operation. It has strong short-circuit resistance and can handle sudden faults calmly. The intelligent voltage regulation system can accurately adapt to voltage fluctuations in the power grid, ensuring the quality of power supply. Widely used in power plants, large substations and other scenarios, providing solid guarantees for the efficient operation of the power system with excellent performance and reliable quality.

Product Features

Adopting high-quality cold-rolled silicon steel core, fully inclined non porous structure combined with low magnetic steel plate pull plate, forming a stable steel body, reducing no-load loss and noise; The winding structure is diverse, combined with transposed wires and computer simulation optimization, to improve electrical characteristics and impact resistance strength; The fuel tank has a flat top design, with reinforced iron walls to enhance mechanical strength and magnetic shielding to reduce stray losses; The positioning device prevents transportation displacement, and the sealed oil storage tank and pointer type oil level gauge ensure stable oil quality; It has excellent impact resistance, short-circuit resistance, low partial discharge, low loss, good sealing performance, and is suitable for key scenarios such as power plants and substations.
