Enhancing Transformer Performance with Advanced Vacuum Oil Filtration

In the power industry, maintaining the purity of insulating oil is critical to the reliable operation of transformers and other high-voltage equipment. Contaminants such as moisture, gases, and solid particles can compromise insulation strength and cause damage to equipment. Vacuum oil filtration technology offers an effective solution for removing these impurities, ensuring the long-term operation and efficient performance of critical electrical installations.
Goldhome Hipot introduces the YD-100 vacuum oil filter: precise cleaning for the needs of the high-voltage industry
Wuhan, China – Wuhan Goldhome Hipot Electrical Co., Ltd., a leading manufacturer of high-tech high-voltage testing equipment, has introduced the YD-100 vacuum oil filter, a two-stage cleaning system designed to meet the stringent oil processing requirements of the energy, metallurgical, and petrochemical sectors worldwide. Leveraging the company's more than 20 years of experience in research and development and its collaborations with leading academic institutions, the YD-100 sets new standards for performance and reliability in oil purification.
Cutting-edge performance: numbers that count
At the heart of the YD-100 is advanced vacuum and precision filtration technology, delivering industry-leading performance metrics:
- Flow rate: 100 litres per minute (6000 litres per hour), enabling rapid processing of large quantities of oil.
- Extremely high vacuum: operates at only 60 Pa, ensuring thorough drying and gas removal to reduce the moisture content in the oil to ≤50 ppm and the gas content to 0.1%.
- Two-stage filtration: Removes contaminants down to 1 micron in size, achieving NAS 1638 Class 4 cleanliness, which is essential for protecting sensitive equipment such as 110 kW+ transformers.
- Robust operation: Supports inlet pressures of -0.4 to 1 bar and provides outlet pressures lower than 8 bar, enabling 150 hours of continuous operation with minimal maintenance.
Designed for industrial flexibility
The YD-100 meets the diverse cleaning needs that arise in the most important sectors:
Energy infrastructure: Ideal for cleaning transformer oil, turbine oil, and lubricating oil in power plants, substations, and railway systems. Supports vacuum lubrication and hot oil circulation during transformer maintenance.
Harsh conditions: Operates reliably in high-altitude areas and industrial environments, such as petrochemical plants and metallurgical facilities, where oil contamination can lead to equipment failure.
Oil regeneration: Restores degraded oils (e.g., hydraulic oil, transformer oil) by removing emulsified water and particles, extending oil life and reducing waste.
The YD-100 embodies the company's commitment to technical excellence. As a state-owned high-tech company with over 30 patents and ISO 9001/14001 certifications, Goldhome Hipot develops products in collaboration with Wuhan University and the State Power Research Institute. 'Our R&D team has focused on solving real-world problems such as frequent filter replacement and inefficient dehydration,' said a company representative. 'The YD-100 evaporation system, with its long service life, eliminates the need for filter replacement and reduces operating costs by 40%.'
Goldhome Hipot products, including the YD-100, are exported to more than 100 countries in Europe, Africa and the Middle East and have won the trust of more than 9,078 customers worldwide. The YD-100 is CE certified and comes with on-site commissioning and lifetime after-sales service. 'We don't just sell equipment - we provide comprehensive solutions,' added the representative. 'From operator training to troubleshooting, our team ensures seamless integration into our customers' workflows.'
