The Double-Stage Vacuum Automation Insulation Oil PU is an automated treatment machine designed for high‑voltage insulation oils. It features a dual‑stage vacuum system with an ultimate vacuum of 5 Pa and a working vacuum of 35 Pa, enabling rapid removal of moisture and dissolved gases. The unit incorporates a 3D stereo‑evaporation chamber and a carbon‑fiber infrared heating system that drives water content down to low ppm levels. Its construction includes a steel frame measuring 1050 mm × 750 mm × 1350 mm and a total weight of 600 kg.
In the insulation‑oil industry, vacuum levels below 10 Pa are typical for achieving high dielectric strength, and flow capacities between 180 L/h and 3000 L/h cover most sub‑station and transformer refurbishment projects. The machine’s reported flow rates correspond to model sizes from ZYD‑A‑30 to ZYD‑A‑300, providing scalability for different throughput requirements. Typical power consumption for similar equipment ranges from 30 kW to 40 kW, aligning with the listed heating power of 30 kW and total power of 35.5 kW. Standard operating temperatures are 20 °C to 80 °C, and noise levels around 75 dB(A) are common.
The equipment is intended for power utilities, transformer manufacturers and maintenance contractors handling oils above 110 kV, as well as for on‑line oil injection during transformer servicing. The supplier notes that the system can treat various oil grades and includes automatic data processing for real‑time control. While flexible MOQ and packaging are mentioned, buyers should confirm the exact shipping terms, such as FOB or CIF, and payment options like L/C or T/T directly with the supplier.
