1250kVA 6kv 10kv 11kv 0.4kv Electrical Three Phase Distribution Power Oil Filled Transformer

Product Description

Product Description Oil immersed transformer uses oil as the main insulation medium and rely on oil as the cooling medium. It adopts a sealed structure to completely isolate the transformer oil from the surrounding air, making the operation of the transformer safer, more reliable, and easier to maintain.

Features:
1. The high-voltage and low-voltage winding of oil immersed transformer generally adopt a cylindrical structure, which ensures a balanced distribution of ampere turns.
2. The coil and core are vacuum dried, and the transformer oil is filtered and injected through a vacuum process.
3. The oil tank adopts corrugated plates, which can compensate for the volume change of oil caused by temperature changes.
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.
