Encapsulated Transformer
The fully sealed transformer is based on the design experience of S7, SZ7, and S9 series transformer products. It prioritizes increasing product functionality, improving product level, and enhancing product reliability. New components, materials, full structure, and improved local structure are used to enhance the electrical strength, mechanical strength, and heat dissipation capacity of the product. A corrugated oil tank and fully sealed structure are adopted to ensure complete isolation between transformer oil and air, extend the service life of transformer oil, and reduce maintenance workload of the transformer.
Features of fully sealed transformer products
1. Transformer oil: Adopting a corrugated oil tank with a fully sealed structure, the corrugated plate wall has two functions of heat dissipation and expansion and contraction. The corrugated plate wall automatically expands and contracts with changes in temperature, load, and transformer oil temperature inside the oil tank. The expansion and contraction capacity of the corrugated plate wall is greater than 10000 times, ensuring complete isolation between transformer oil and air, and does not require maintenance during the service life of the transformer.
2. Safety protection: Fully sealed transformers are equipped with pressure relief valves, expanding the application range of pressure relief valves and providing effective safety protection for the product.
3. Tap changer: Adopting a new type of double sealed vertical switch, the sealing performance of the switch has been improved.
4. Fasteners inside the box: New anti loosening nuts are used to ensure that the fasteners on the transformer body do not loosen during transportation.
5. Connection between the device body and the box cover: A suspension plate with a buffer structure is used to ensure that the device body can "land" and not top the box cover.
6. Before installation, unscrew the top nut of the air plug and check the oil level. If the oil level is below 50mm from the top, add transformer oil of the same oil grade to 30mm from the top.

Disadvantages of fully sealed transformers
The price of expansion and contraction components for fully sealed transformer oil volume changes (corrugated sheets or expansion radiators) is relatively high, especially for their production equipment such as corrugated oil tank production lines Make the cost of fully sealed transformers higher and the product price more expensive. The corrugated fins of the corrugated fuel tank and the expansion fins of the expansion radiator cannot be made very thick due to their elasticity. In case of oil leakage, welding repair will be more difficult.
Fully sealed transformers some have oil level indicators; Some do not have an oil level indicator and require a probe to measure the oil level, which makes it difficult to monitor the oil level and color.
For commercial applications where airborne contaminants are present, HPS general-purpose encapsulated transformers offer a cost-effective solution that prioritizes safety, quality and ease of installation and maintenance.
The core and coil are completely encapsulated in epoxy and silica, providing excellent protection against airborne particles and moisture build-up inside the transformer enclosure.
Encapsulated transformers include transformers that are enclosed in a casing or coating. Transformers are encapsulated to protect components from contaminants present in the working environment, such as moisture, gases, dust, or dirt. They may also be encapsulated to meet spark-resistance requirements (for use near potentially explosive gases for example).
In addition to environmental protection, encapsulation can also dissipate heat from the core and windings, reducing temperature differentials around the windings and enabling the transformer to perform reliably in higher-temperature environments.
