Key Performance Strengths
- Outdoor Adaptability: Thanks to its excellent heat dissipation performance, the transformer is well-suited for outdoor open-air installation (when equipped with a dedicated protective shell). The protective shell—usually made of galvanized steel with a corrosion-resistant coating—shields the transformer from rain, dust, and direct sunlight. This allows the transformer to operate normally in high-temperature environments (e.g., summer outdoor temperatures exceeding 35°C) and short-term high-load conditions (e.g., holiday peak electricity use in rural areas), avoiding shutdowns caused by overheating.
- Load Flexibility: The transformer’s mineral oil cooling system has a large heat capacity, enabling it to withstand short-term overloads (e.g., 120% of rated load for 2 hours) without damaging internal components. This flexibility is critical for scenarios where load fluctuates significantly, such as temporary construction sites or suburban markets with busy and quiet periods.
