Hermetically Sealed Oil Filled Transformer

The hermetically sealed oil-immersed transformer features a precision-processed core (high-grade silicon steel, high permeability, low losses), copper windings tailored to different voltages for efficient power transmission, and insulating oil that provides both insulation and cooling to prevent overheating damage.

The fully sealed design prevents external environmental factors such as moisture and dust from affecting the transformer's interior. By sealing the oil tank, the insulating oil inside the transformer remains stable for a long time, thus ensuring the normal operation of the equipment. This design extends the transformer's service life and also reduces maintenance costs.

Laminated Silicon Steel Core

The hermetically sealed oil filled transformer consists of a core, windings and insulating oil. The core is made of high-quality silicon steel sheets and demonstrates high magnetic permeability and low losses after precision processing. The windings are constructed from superior copper wires, designed according to different voltage levels to ensure efficient power transmission. Apart from insulation, the oil also serves as a cooling medium to prevent the transformer from damage due to overheating.

The hermetically sealed oil filled transformer is widely used in the fields of power and industry. In power systems, the transformer undertakes the tasks of voltage conversion and power distribution for substations and distribution networks. And in industrial scenarios, the transformer can provide stable electrical energy for production.

Multi-layer Insulated Windings

New insulating materials have improved the transformer's temperature resistance. Consequently, the transformer can adapt to more demanding operating environments. In addition, intelligent monitoring technology allows operators to monitor the transformer's operating status in real time and issue early warnings for potential faults to prevent accidents.

Maintenance is crucial for the long-term stable operation of the hermetically sealed oil filled transformer. Regular inspection of key indicators such as insulation resistance, oil quality and temperature can help detect potential issues early. Moreover, keeping the transformer's exterior clean and ensuring good ventilation also help to extend its service life.
