2000L/H Online Insulating Oil Filtration System for OLTC On-Load Tap Changers

REXON ZYL-20(2000L/H) Online Insulating Oil Filtration System is an intelligent online oil purification solution specially designed for continuous circulation filtration of insulating oil in on-load tap changers of power transformers.

During normal transformer operation, the on-load tap changer generates carbon particles, metallic wear debris, and trace moisture, which can adversely affect switching performance and insulation reliability. The REXON ZYL-20 online oil filtration system operates without interrupting transformer service, continuously removing contaminants and maintaining optimal oil cleanliness inside the tap changer.

REXON ZYL-20 online insulating oil filtration system is widely applied in:
1. On-load tap changers of 35kV and above power transformers.
2. Power transmission and distribution substations.
3. Utility companies, EPC contractors, and transformer maintenance service providers.
4. OLTC systems requiring online oil conditioning and condition-based maintenance.

By maintaining stable oil quality, the system effectively improves OLTC operating reliability, reduces maintenance frequency, and extends the service life of both insulating oil and tap changer components.

1. True online operation during normal transformer service, no shutdown required.

2. Efficient removal of free carbon, metallic particles, and fine contaminants.

3. Reduction of trace moisture, improving insulation performance.

4. Enhanced safety and reliability of OLTC switching operations.

5. Reduced unplanned outages and extended maintenance intervals.

6. Prolonged insulating oil service life and lower operating costs.

7. Intelligent control system with manual, automatic, and timed operation modes.

8. Comprehensive protection including pressure, motor overload, phase-loss, and fault alarms.

9. Energy-saving, low oil consumption, and environmentally friendly design.

10. Reliable performance suitable for long-term continuous operation in substations.
