3 Phase Oil Immersed Power Transformer Rated Capacity 12500KVA Tapping Range Plus Minus 2 Times 2.5 Percent Ensuring Electrical Distribution

Product Description:

The Oil Immersed Power Transformer is a highly efficient and reliable piece of electrical equipment designed to meet the demanding requirements of modern power distribution systems. With a rated capacity of 12500KVA and a rated voltage of 67/13.2 KV, this transformer is engineered to provide stable and consistent voltage transformation in various industrial, commercial, and utility applications. Its robust design ensures optimal performance under different operating conditions, making it a preferred choice for power distribution networks.

One of the standout features of this Oil Immersed Power Transformer is its advanced cooling method, known as ONAF (Oil Natural Air Forced). This cooling technique uses natural circulation of oil inside the transformer tank combined with forced air cooling on the radiator surfaces. The ONAF cooling system significantly enhances the transformer's ability to dissipate heat, thereby improving its thermal efficiency and extending its operational lifespan. This method is particularly effective in maintaining the transformer's temperature within safe limits, even under heavy load conditions, ensuring safe and uninterrupted power supply.

The transformer is designed as a three-phase unit, which is essential for most power distribution systems that require balanced and efficient power transfer. The three-phase configuration allows for smoother operation and better handling of electrical loads, reducing losses and increasing overall system reliability. This makes the Oil Immersed Transformer suitable for a wide range of applications, from industrial plants to large commercial complexes and utility substations.

Humidity levels can have a significant impact on the performance and longevity of transformers. The Oil Immersed Power Transformer is optimized to operate efficiently at a humidity level of 50%, which is typical for many geographic locations. The oil immersion provides excellent insulation and moisture protection, preventing the ingress of moisture into the winding and core materials. This protection is crucial in maintaining dielectric strength and preventing insulation failure, which can lead to costly downtime and repairs.

Oil Immersed Distribution Transformer technology has been proven over decades to offer superior insulation, cooling, and protection compared to dry-type transformers. The mineral oil used in the transformer not only serves as an insulating medium but also acts as a coolant, absorbing the heat generated by the electrical currents and dissipating it through the cooling system. This dual function of the oil enhances the transformer's efficiency and reliability, making it suitable for high-voltage and high-capacity applications.

Additionally, the Oil Immersed Transformer is constructed with high-quality materials and adheres to stringent manufacturing standards to ensure durability and long service life. The transformer's tank is designed to withstand mechanical stresses and environmental factors, including temperature fluctuations and physical impacts. The use of high-grade insulation paper and copper windings further contributes to the transformer's efficiency and thermal stability.

Maintenance of the Oil Immersed Power Transformer is straightforward due to its design, which allows easy access to key components for inspection and servicing. Regular maintenance ensures that the transformer continues to operate at peak performance and minimizes the risk of unexpected failures. The oil can be periodically tested and filtered to maintain its insulating properties and cooling effectiveness.

In summary, the Oil Immersed Power Transformer with a rated capacity of 12500KVA, rated voltage of 67/13.2 KV, and ONAF cooling method is an excellent solution for reliable and efficient power distribution. Its three-phase design, optimized for 50% humidity environments, along with the superior insulating and cooling properties of oil immersion, makes it an ideal choice for a wide range of applications. Whether used in utility substations, industrial facilities, or commercial buildings, this Oil Immersed Distribution Transformer provides dependable performance, enhanced safety, and long service life, ensuring that your power distribution needs are met with excellence.
