ZJA18
18000LPH Double Stage Transformer Oil Filtration Machine
- ZJA double stage transformer oil filtration machine‘s purpose is to filter impurities in waste transformer oil.
- Enhances transformer oil properties for 66KV to 500KV power transmission projects.
- Removes trace water, gas, and particulate matter from insulating oil.
- Improves the performance of transformers, circuit breakers, mutual inductors, cables, and capacitors.
- Components all rely on an insulation system.
18000LPH transformer oil filtration machine (also known as transformer oil purification plant, transformer oil purifier) is a specialized piece of industrial equipment. Compared to traditional transformer oil centrifuging methods, this system offers superior efficiency in cleaning, drying, and degassing insulating oil used in electrical transformers and other high-voltage equipment like circuit breakers and reactors.
Its primary function is to restore and maintain the dielectric strength and chemical properties of the oil, which is crucial for the safe, efficient, and long-lasting operation of the transformer.

1. Improved Dielectric Strength:
By effectively eliminating contaminants, the oil’s insulating properties are restored, reducing the risk of electrical breakdowns.
2. Higher Efficiency and Speed:
The dual-stage vacuum system achieves deeper purification than standard transformer oil centrifuging processes, allowing for faster handling of large oil volumes and minimizing downtime for transformers during maintenance.
3. Energy Optimization:
Staged heating and vacuum systems reduce energy consumption compared to single-stage machines running at peak capacity continuously.
4. Extended Transformer Lifespan:
Cleaner oil reduces oxidation and sludge buildup, preserving the transformer’s insulation system and mechanical components.
- Oil Processing During Transformer Installation: A more advanced alternative to basic transformer oil centrifuging, this machine is used for filtering and dehydrating new oil before filling a new transformer or after major repairs.
- Dry-Out of Transformer Insulation: Used in conjunction with heat and vacuum to dry out the paper/cellulose insulation inside a transformer’s core, often during commissioning or after exposure to moisture.
- On-Line Filtration (Continuous): Machines connected to a live transformer’s conservator tank to continuously remove moisture and particles, extending service life.
- Oil Recovery from Faulty Transformers: Processing oil from a transformer that has experienced an internal fault (e.g., arcing) to make it reusable after the hardware repair.
