FAQ
Q1: How do I select an oil purifier based on transformer voltage levels?
≤35kV: Single-stage vacuum oil purifier; breakdown voltage ≥55kV after treatment.
110–220kV: Double-stage vacuum oil purifier; breakdown voltage ≥65kV after treatment.
500–750kV: High-performance double-stage vacuum purifier (regeneration unit optional); breakdown voltage ≥70kV after treatment.
Q2: How do I select the flow rate?
Common specifications: 50/100/150/200/300 L/min.
Rule of thumb: Oil tank volume ÷ 4–6 hours = recommended flow rate; choose a higher flow rate if the oil has high moisture content.
Q3: Can it filter other types of oil?
Primarily designed for transformer insulating oil (mineral oil).
Compatible with: Instrument transformer oil, circuit breaker oil, and hydraulic oil (material compatibility must be verified).
Not recommended for: Edible oil, high-viscosity gear oil, or oils containing high levels of additives.
