Advantages
1. The vacuum side of this ZYD unit pulls –0.08 to –0.099 MPa and removes free water, dissolved moisture, and fault gases (hydrogen, methane, ethylene) all in one pass. With the right temperature and flow settings, you typically see water drop below 3 ppm and gas under 0.1% – that's been verified in the field.
2. For solids, the multi‑stage composite filters catch carbon dust, metal wear particles, and oxides down to 1 micron, which gets you to NAS 1638 Class 6 cleanliness. A pressure gauge on each stage tells you which filter is loading up, so you only swap the one that's plugged – not the whole set.
3. The indirect heater keeps the oil at a controlled temperature without any hot spots, so you avoid thermal breakdown while still keeping viscosity low enough for vacuum operation. And the heater only runs when the flow switch confirms oil is moving – no dry‑firing.
4. The interlock system covers pressure, temperature, and liquid level across the board. If any of those goes out of range, the unit cuts power immediately – that's standard protection for any serious insulating oil processing job, and it's the same setup you get with this ZYD equipment for insulating oil processing.
FAQ
Q: How long does the improved breakdown voltage last after treatment?
A: It depends on the transformer's operating condition. If the oil is processed and the transformer runs without new contamination (e.g., leaking seals or active overheating), breakdown voltage typically stays above 60 kV for months.
Q: What if I need spare parts or technical support after purchase?
A: We stock replacement filter cartridges, seals, and heating elements for all ZYD models.For technical support, our team responds via email or WhatsApp within 24 hours-we'll walk you through troubleshooting with photos or video calls.
Q: What if the transformer tank has a different oil level than the machine's inlet?
A: The machine has its own oil pump that draws oil from the transformer regardless of tank level, as long as the inlet hose is submerged. We recommend positioning the machine at or slightly below the tank's bottom level to ensure positive suction. If the transformer is underground or the oil level is well below the machine, you may need a longer inlet hose-keep it under 5 meters to maintain rated flow; over 5 meters, flow rate drops by roughly 10% per additional meter.
Q: Is there a risk of introducing air into the transformer while processing?
A: No-the machine is designed as a closed-loop system. Oil flows from the transformer through the machine and returns via the outlet hose. The vacuum section removes air from the oil before it returns, so you're actually reducing dissolved gas content, not adding it. The only potential air entry point is if the inlet hose is not fully submerged and sucks air instead of oil-keep the inlet below the oil surface at all times.
