I. Technical Features
-
Ultra-low Noise Operation: High-purity amorphous alloy strips are selected, which inherently possess low magnetostrictive properties, reducing vibration and noise at the source. Meanwhile, multi-layer shock-absorbing pads are added at the connection between the iron core and the oil tank, and an elastic constraint structure is adopted for winding fixation. With these dual measures, the operating noise is controlled below 50dB, far lower than that of traditional transformers. It is particularly suitable for noise-sensitive places such as residential areas, hospitals, and schools.
-
High-efficiency & Low Temperature Rise Design: The internal flow guide structure of the heat sink is optimized, and a "multi-channel turbulent flow" design is adopted, which improves the cooling oil circulation efficiency by more than 30%. Combined with the finned radiator with an increased heat dissipation area, the heat dissipation capacity is significantly enhanced, ensuring that the temperature rise does not exceed 50K under rated load. This effectively delays the aging of insulating materials and extends the service life of the transformer to more than 30 years.
II. Special Structural Design
-
High-strength Stable Tank Body: The oil tank adopts a fully welded frame structure. The main frame is made of Q345 high-strength steel, and the key parts are processed by numerical control to ensure dimensional accuracy, improving the overall deformation resistance by 40%. Reinforcing ribs are added at the bottom of the tank body, and combined with the anti-slip base, it can withstand severe impacts during transportation and installation, and has better stability during operation.
-
High-altitude Adaptability Optimization: A 10%-15% air cushion layer is reserved at the upper part of the oil tank, which can automatically balance the internal and external air pressure as the altitude increases (adaptable to a maximum altitude of 4500 meters), avoiding abnormal oil level caused by low air pressure. At the same time, the insulating bushings are made of enhanced weather-resistant materials to improve the breakdown voltage of the air gap, ensuring stable and reliable insulation performance in high-altitude and low-air-pressure environments.
