A vacuum transformer oil purifier is a device specifically designed to remove impurities and contaminants from transformer oil. These impurities, such as water, air, and solid particles, can reduce the oil's dielectric strength, leading to reduced transformer efficiency and an increased risk of electrical failure. By effectively purifying the oil, these machines help extend the life o... https://www.yunengoilpurifier.com/vacuum-transformer-oil-purifiers-maintaining-transformer-health
