Project Overview
In June 2025, a large-scale transformer oil filtration project was implemented for China CRRC (China Railway Rolling Stock Corporation), one of the leading manufacturers of rail transportation equipment. The objective was to maintain and improve the performance of transformers in the company’s power systems by purifying the transformer oil, which had accumulated moisture and contaminants over time.
ZYD-300 Transformer Oil Filtration Machines (x2): These units provide a combined processing capacity of 18,000 L/h, offering continuous, reliable oil purification and extending the life of the transformers.
