The Double Stage Vacuum Transformer Oil Purifier from Chongqing Hopu Filtration Plant Manufacture Co.,Ltd is engineered to regenerate degraded insulating oil in high-voltage power equipment, specifically for systems above 110kV. It achieves a vacuum level of 5 Pa at peak and 35 Pa during operation, with a suction rate of 333 L/s. The unit maintains dielectric strength at 75 kV, reduces dielectric loss to 0.001% at 90°C, and lowers acid value to 0.03 mg KOH/g, with a pH of 5.5 and flash point of 145°C. It integrates a carbon fiber infrared heating system to eliminate trace acetylene and a dual FH trapezoidal filtration network for particulate removal without mechanical power.
The purification process uses duplex 3D stereo-evaporation to rapidly remove free water and employs UK G technology to extract dissolved water molecules, a critical requirement for transformer oil integrity. The system is designed for online treatment without disassembly, allowing continuous operation during maintenance cycles. Typical industry standards for transformer oil require moisture content below 10 ppm and particulate contamination under ISO 4406 Class 16/14; this unit is built to meet or exceed those thresholds. It does not rely on chemical additives, preserving the oil’s natural dielectric properties.
This equipment is primarily purchased by power utilities, transformer manufacturers, and industrial maintenance teams servicing substations, railway electrification systems, and petrochemical plants. It is suitable for treating mineral dielectric oil, switchgear oil, and mutual inductor fluid. The purifier supports on-site operation and can be integrated into existing transformer oil handling workflows. Delivery is typically FOB Chongqing Port, with standard packaging in steel frame containers. MOQ and lead time must be confirmed directly with the supplier, as these vary with configuration and export destination.

Before ordering, verify the purifier’s compliance with local electrical safety standards and confirm the material grade of internal components, especially those in contact with oil. Request a material certificate for the stainless steel tanks and piping, and validate the insulation rating of the heating elements. Do not assume the unit meets international standards unless explicitly documented. Ensure the supplier provides a functional test report under load conditions, not just static measurements.
Confirm the Incoterms offered - typically FOB Chongqing Port - and whether the supplier arranges export documentation, including the commercial invoice, packing list, and certificate of origin. Lead time is not stated but typically ranges from 30 to 60 days depending on configuration. Payment terms are usually 30% advance and 70% against copy of B/L. Request a detailed shipping plan including container dimensions and weight to ensure port and crane compatibility.
Upon delivery, conduct a visual inspection for transport damage and verify all components match the packing list. Perform a dry run with distilled water before introducing transformer oil. Request a post-installation performance report including dielectric strength, moisture content, and particle count before accepting the unit. Retain all test data for warranty claims. Insist on a calibration certificate for the vacuum gauge and temperature sensors if they are critical to your operations.
