3 Phase Oil Immersed Transformer Featuring Breakdown Voltage 65.2kV Designed for Power Transmission and Distribution Systems

Product Description:

The Oil Immersed Power Transformer with a rated capacity of 12500KVA is a highly reliable and efficient electrical device designed to meet the demanding requirements of modern power distribution systems. Manufactured in accordance with the IEC60076 standard, this transformer ensures superior performance, safety, and longevity, making it an ideal choice for various industrial, commercial, and utility applications. The robust design and advanced features of this Oil Immersed Transformer make it a vital component in power grids, enabling the safe and efficient transfer of electrical energy across different voltage levels.

One of the defining characteristics of this Oil Immersed Transformer is its use of oil as the insulating and cooling medium. The transformer windings and core are immersed in high-quality insulating oil, which serves multiple functions. It provides excellent electrical insulation, preventing short circuits and breakdowns, while also acting as a heat transfer medium to dissipate the heat generated during operation. This oil immersion significantly enhances the transformer's thermal performance, ensuring stable operation even under heavy load conditions.

The cooling method employed in this transformer is ONAF (Oil Natural Air Forced), a highly efficient cooling system that combines natural oil circulation with forced air cooling. In this method, the oil naturally circulates within the transformer tank to absorb heat from the windings and core. Simultaneously, external fans blow air over the radiators to accelerate the cooling process. This dual cooling mechanism allows the transformer to operate at optimal temperatures, improving its efficiency and extending its service life. The ONAF cooling method is particularly advantageous for transformers with higher rated capacities, such as this 12500KVA model, as it effectively manages the thermal stresses associated with heavy electrical loads.

The connection group of this Oil Immersed Transformer is Dyn1, which indicates a delta connection on the primary winding, a star connection with neutral on the secondary winding, and a phase displacement of 30 degrees leading. This connection configuration is widely used in power distribution networks as it provides several benefits, including the ability to supply both three-phase and single-phase loads, improved fault tolerance, and reduced harmonic distortion. The Dyn1 connection group also facilitates the grounding of the neutral point, enhancing system stability and safety.

Designed to operate efficiently in environments with up to 50% relative humidity, this Oil Immersed Transformer incorporates features that protect it from moisture ingress and corrosion. Proper sealing and the use of moisture-resistant materials ensure that the internal components remain dry and functional, preventing deterioration of the insulating oil and electrical insulation. This makes the transformer suitable for installation in a variety of climatic conditions, including humid regions, without compromising its performance or reliability.

Compliance with the IEC60076 standard guarantees that this transformer meets internationally recognized criteria for design, testing, and operation. Adherence to these standards ensures that the product is safe, durable, and compatible with other equipment in the power system. Customers can trust that this Oil Immersed Transformer has undergone rigorous quality control and testing procedures to deliver consistent and dependable performance throughout its operational life.

In summary, the Oil Immersed Power Transformer with a rated capacity of 12500KVA, Dyn1 connection group, and ONAF cooling method represents an excellent solution for power transmission and distribution needs. Its oil immersion technology ensures superior insulation and cooling, while its compliance with IEC60076 standards guarantees quality and safety. The transformer's ability to operate efficiently in humid conditions and its optimized connection configuration make it a versatile and dependable choice for various electrical infrastructure projects. Whether deployed in industrial plants, substations, or commercial facilities, this Oil Immersed Transformer delivers reliable performance, operational efficiency, and long-term durability.
