**Application:**
The Zhongneng Vacuum Transformer Oil Filtering Machine is designed for the purification of 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 function as a vacuum oil injection and vacuum drying system for transformers. It offers cost-effective operation, ease of use, and high performance.

**Features:**
1. Equipped with a Roots Pump vacuum system in addition to a vacuum pump, which significantly increases the speed of air evacuation. The limited vacuum reaches ≤ 5 Pa, and the working vacuum is ≤ 35 Pa.
2. Utilizes a large-area three-dimensional flash distillation technique along with an advanced dewatering and degassing system, ensuring efficient and complete 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 the transformer oil can reach up to 70 kV.
5. Incorporates an advanced double-infrared liquid level automatic controller and pressure automatic protector, ensuring long-term safe and reliable operation.
6. Can be operated both on-load and off-load.
7. Designed with user-friendliness in mind, featuring a low-noise pump, deep purification capability, and long-term free technical support.
8. Available in various types, including general type, trailer-mounted type, and hermetical type.

**Advantages:**
Compared to single-stage vacuum oil purifiers, this machine removes water, gas, and impurities more efficiently and thoroughly, significantly improving the oil's breakdown voltage. Its bridge-type vacuum linking 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.
