S22-M Fully Sealed Oil-Immersed Transformer - Low Voltage 400 Volts, High Voltage 10 Kilovolts, 1600 Kilovolt-Amperes

Fully sealed and maintenance-free design.

The transformer adopts a fully sealed structure design, with the oil tank completely isolated from the outside air. The insulating oil will not oxidize or deteriorate due to contact with air, nor will it absorb moisture from the air. This effectively avoids problems of insulation aging and deterioration of the oil quality. Compared with traditional non-sealed transformers, there is no need for regular oil replenishment or oil replacement maintenance work, significantly reducing the workload and cost of operation and maintenance. At the same time, the fully sealed design can prevent dust, impurities, etc. from entering the transformer interior, reducing the wear and corrosion of internal components.

Intelligent monitoring and early warning function

Transformers are generally equipped with intelligent monitoring systems, which can monitor key operating parameters such as oil temperature, winding temperature, oil level, insulation status, and load current of the transformer in real time. The monitoring data is transmitted to the background monitoring center through wireless communication modules, allowing staff to remotely and in real time grasp the operating status of the transformer. When the monitoring parameters exceed the set thresholds, the system will automatically issue audible and visual alarms and promptly push warning information to relevant personnel, facilitating the early detection of potential fault hazards and preventing the expansion of faults.

Low-noise green operation

The transformer achieves low-noise operation by optimizing the core structure, using shock-absorbing materials and implementing a fully sealed design. Its no-load noise level is ≤ 45 dB(A), and the load noise level is ≤ 55 dB(A), which is 10-15 dB(A) lower than that of traditional transformers and meets the noise requirements of national environmental protection standards. The core adopts a fully inclined joint stacking process, reducing the noise generated by magnetic expansion; the coil winding is tightly arranged, lowering the electromagnetic vibration noise; rubber shock-absorbing pads are installed at the bottom of the oil tank and the bottom bracket to effectively absorb the vibrations generated during operation and reduce noise transmission. The low-noise design enables the S13 transformer to be directly installed in areas with noise sensitivity such as residential communities and commercial centers, enhancing the comfort of the power environment and contributing to the construction of a green city.
