**Application:**
The Zhongneng Vacuum Transformer Oil Filtering Machine is specifically designed for purifying used or aged transformer oil, ultra-high-voltage transformer oil, switch oil, and other insulating oils. It is ideal for power distribution stations, power grids, and companies that require regular maintenance of oil-immersed transformers. In addition to standard oil purification, this machine can also be used for vacuum oil injection and vacuum drying of transformers. It is cost-effective, easy to operate, and provides excellent performance.

**Key Features:**
1. Equipped with a Roots Pump vacuum system in addition to a vacuum pump, allowing for faster air evacuation and achieving a limited vacuum of ≤5 Pa and working vacuum of ≤35 Pa.
2. Utilizes large-area three-dimensional flash distillation technology combined with an advanced dewatering and degassing system for efficient removal of water and gas.
3. Features a precise filtration system with high-quality filter elements and multi-stage filtration with gradually increasing precision, effectively removing mechanical impurities from the oil.
4. After purification, the breakdown voltage of transformer oil can reach up to 70 kV.
5. Includes an advanced dual-infrared liquid level automatic controller and pressure automatic protector, ensuring safe and reliable long-term operation.
6. Can be operated both on-load and off-load, offering greater flexibility.
7. Designed with user-friendliness in mind, featuring low-noise pumps, deep purification capabilities, and free long-term technical support.
8. Available in various types such as general, trailer-mounted, and hermetical models to suit different needs.

**Advantages:**
Compared to single-stage vacuum oil purifiers, this machine offers faster and more complete dehydration, degassing, and impurity removal, significantly improving the oil’s breakdown voltage. Its bridge-type vacuum linkage system allows it to function not only as a filtration system but also as an independent vacuum power supply for vacuum oiling in power equipment.
