Excellent heat dissipation & insulation: Insulating oil serves as both cooling medium and dielectric material. It features high heat transfer efficiency for high voltage & large capacity applications and strong short-time overload capability.
High reliability & long service life: With proper maintenance, service life reaches 25–35 years. Strong short-circuit resistance for continuous long-term operation.
Cost-effective: Lower investment cost compared with dry-type transformers at the same rating, especially for large-capacity projects.
Adaptable to harsh outdoor conditions: Rainproof and dustproof, stable operation under high temperature, dusty and remote field environments.
Convenient condition monitoring: Internal faults can be predicted via oil sampling and gas analysis for predictive maintenance.
Notes: Insulating oil is flammable. Fire protection and anti-leakage measures are required during installation. Periodic inspection of oil level and oil quality is necessary.
