Oil-immersed transformers rely on oil for their main insulation. They also depend on it to cool down effectively. As a type of oil type transformer, these units find wide use in distribution transformer and power distribution transformer setups. This helps send energy in a steady way. This SHENGTE three phase transformer comes with a fully sealed design. The design keeps transformer oil away from outside air. It stops oxidation and moisture from getting in. As an important electrical power transformer, the unit gives safer runs, better reliability, stronger thermal performance, and less need for upkeep over long periods.

Features:

1. The high-voltage and low-voltage windings in this oil-immersed transformer use a cylindrical shape. This setup gives balanced ampere-turn distribution. It also keeps electromagnetic performance steady.  

2. The coil and core of this three phase transformer go through vacuum drying. At the same time the transformer oil is filtered and injected under vacuum. These steps build high insulation strength. The result is strong long-term stable operation in power systems.  

3. The oil tank uses corrugated plates. These plates balance oil volume shifts from temperature changes. The design improves how oil-immersed transformers work in modern power distribution transformer networks. It also raises safety and makes daily operation more reliable.

Our Advantages:

1. The spiral coil with longitudinal oil duct, has the performance of good heat dissipation, low magnetic leakage, high mechanical strength; And the reliable supporting structure can greatly improve the short circuit withstand ability.

2. The iron core adopts the stacked structure, it is composed of the silicon steel sheets with thickness less than 0.35mm and high magnetic conductivity, which can reduce the no-load loss and no-load current of the transformer.

3. The insulation materials have high heat resistance, which can withstand overvoltage and overcurrent during operation.

4.The transformer oil has low viscosity, good heat transfer performance and insulation performance, which can effectively protect the iron core and winding, reduce the aging of the insulation materials, and extend the service life of the transformer.

5. The corrugated oil tank is manufactured from high-quality cold-rolled steel plates on a dedicated production line, its surface is treated with deoiling, rust removal, and phosphating before being coated with a three proof (rain proof, moisture proof, and salt spray proof) paint, which can enhance operational reliability and durability, reduce the maintenance costs.

6. The sealing rings are made of the high-quality rubber materials, which can effectively slow the aging process, isolate the external air and prevent the transformer oil leakage.
