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