SBH - Hermetically Sealed Maintenance-Free Oil-Immersed Power

² Voltage level: 10~35/0.4kV

² Capacity: 30~2500kVA

² Hermetically Sealed and Reliable with a Long Service Life: The fully hermetic structure completely isolates transformer oil from the external environment, preventing oil oxidation, insulation moisture absorption, and impurity intrusion—greatly extending the equipment's service life. Meanwhile, it resists corrosion from harsh environments and reduces failure risks, serving as a core guarantee for the long-term stable operation of the equipment.

² Energy-Efficient and Cost-Effective in Operation: Adopting an oil-immersed self-cooled design, it requires no auxiliary energy consumption. Combined with an optimized core-type magnetic circuit and double-winding structure, both no-load loss and load loss are maintained at low levels. It delivers significant energy-saving effects during long-term operation, continuously reducing users' electricity costs and meeting the demand for cost reduction and efficiency improvement.

² Stable Structure with Strong Anti-Interference and Durability: The three-phase core-type structure features a symmetrical magnetic circuit, ensuring stable power supply voltage and reducing harmonic interference. The double windings boast high mechanical strength, excellent short-circuit resistance, seismic resistance, and vibration resistance—capable of withstanding power grid impacts and the challenges of complex installation environments, thus minimizing the probability of downtime due to faults.

² Convenient Maintenance and Low Comprehensive Cost: The hermetic structure eliminates the need for oil refilling or replacement, requiring only simple daily inspections. The off-circuit tap-changing design is simple with a low failure rate, eliminating the need for frequent maintenance by professional personnel. This not only saves labor and time but also reduces maintenance procedures and environmental pressure.

² Wide Adaptability and Flexible Application Scenarios: The three-phase design is compatible with mainstream power systems, and the double-winding structure accurately matches voltage transformation between two levels. The combined characteristics of hermetic sealing and self-cooling make it suitable for various scenarios, including outdoor, indoor, high-humidity, and dusty environments. It can meet the power distribution needs of urban and rural power grids, industrial facilities, commercial buildings, residential areas, and other applications.

The S-M Series Three-Phase Oil-Immersed Self-Cooled Hermetically Sealed Off-Circuit Tap-Changing Core-Type Double-Winding Distribution Transformer, leveraging its core advantages of reliable hermetic sealing, high energy efficiency, and wide adaptability, is widely applied in various three-phase power distribution network scenarios, covering fields such as urban and rural power grid construction, industrial production, commercial and public buildings, outdoor and special environments, as well as people's livelihood and infrastructure supporting facilities.
