Transformer oil filters are critical equipment for power system maintenance. Through vacuum dehydration and precision filtration technologies, they effectively remove moisture, gas, and impurities from the oil, restoring insulation performance and ensuring the safe and stable operation of transformers. Modern oil filters feature automated control and multiple protection functions, and are widely used in industries such as power, petrochemicals, and metallurgy, playing a vital role in extending equipment life and improving power supply reliability.
Chongqing Tongrui Filtration Equipment Manufacturing Co., Ltd., as a professional oil filtration equipment manufacturer, has independently developed the ZJA series transformer oil vacuum filters. Utilizing advanced technologies such as dual-stage high vacuum and three-dimensional flash evaporation, its dehydration and degassing efficiency is 3-5 times higher than ordinary equipment, with a filtration accuracy of up to 1 micron and an oil breakdown voltage ≥55kV, meeting the stringent requirements of 110-500kV ultra-high voltage power grids. The company's products cover the entire ZJA-10 to ZJA-400 series, featuring vacuum oil injection, online purification, and live-line working functions. With a 12-month warranty and nationwide on-site installation and commissioning services, the company is a trustworthy partner in the power industry.
