Product Advantage

Product Advantage
  1. ‌1. Superior cooling efficiency‌
    Insulating oil provides excellent heat dissipation, allowing higher overload capacity and sustained performance in high-load scenarios (e.g., 1.3× rated capacity for 2 hours). This makes them ideal for industrial and utility-scale applications.


  2. 2‌. High voltage tolerance‌
    With robust insulation from dielectric oil, they support voltage levels exceeding 35 kV (up to 110 kV+), suitable for transmission grids and large substations.


  3. 3‌. Enhanced thermal stability‌
    Oil circulation prevents hot spots, enabling stable operation in high-ambient temperatures. Sealed designs (e.g., conservator tanks) minimize oxidation and moisture ingress.


  4. 4‌. Lower noise levels‌
    Oil dampens core vibrations, reducing operational noise to 50–60 dB(A), quieter than many dry-type alternatives under heavy loads.


  5. 5‌. Cost-effectiveness‌
    Lower manufacturing costs and extended service life (20–30 years with maintenance) provide long-term economic benefits, especially for capacities >1,000 kVA.


  6. 6‌. Strong short-circuit withstand capability‌
    Mechanically reinforced windings and oil insulation offer high resistance to short-circuit currents, critical for grid stability.


  7. 7‌. Adaptability to harsh environments‌
    Suitable for outdoor installations (e.g., substations, pole-mounted units) and extreme climates, including cold regions with specially formulated oil.
