1. High Operational Reliability: Using mineral insulating oil as the cooling and insulating medium, it can stably withstand long-term overload operation, has better resistance to short-circuit impacts than dry-type transformers, and has a lower failure downtime rate.
2. Low Maintenance Costs: With a simple and mature structure, routine maintenance only requires periodic checks of oil level, oil quality, and insulation performance. A single unit can have a service life of 20-30 years, far exceeding the service life of some dry-type transformers.
3. Excellent Heat Dissipation Efficiency: The insulating oil can quickly conduct heat from the windings, and when used with a radiator, it can achieve stable heat dissipation under high-power transformer conditions, making it suitable for ultra-large power transformer scenarios.
4. Stable Insulation Performance: The insulation performance of mineral oil is less affected by ambient temperature, maintaining stable insulation strength even in high-temperature and high-humidity environments, making it suitable for complex outdoor operating conditions.
5. Controllable Procurement Costs: With mature production processes and a complete supply chain, the procurement price for the same capacity and specifications is 30%-50% lower than that of dry-type transformers with the same parameters.
