Product Description:
The Oil Immersed Transformer is a robust and highly efficient electrical device designed to meet the diverse needs of modern power distribution systems. This transformer is specifically engineered to operate with oil immersion cooling, which significantly enhances its thermal performance and prolongs its operational lifespan. By submerging the internal windings and core in high-quality insulating oil, the transformer ensures optimal heat dissipation, maintaining reliable functionality even under demanding load conditions. This makes the Oil Immersed Transformer an ideal choice for various industrial, commercial, and utility applications.
One of the key features of this transformer is its adaptable voltage rating. It typically supports standard voltages such as 12.47kV/7.2kV and 13.8kV/480V, but it can also be customized to meet specific project requirements. This flexibility allows users to integrate the transformer seamlessly into existing power grids or new installations without compromising performance. Whether you need a transformer for stepping down medium voltage supply to a lower voltage level or for specialized applications, the customizable voltage rating ensures it can be tailored to your exact needs.
The Oil Immersed Transformer is designed as a three-phase unit, providing balanced and efficient power delivery across all three phases. This is essential for industrial environments where large motors and heavy machinery require steady and reliable three-phase power. The inclusion of common connection configurations such as Yyn0 and Dyn11 enhances its versatility. These connection groups are carefully selected to optimize phase displacement and voltage regulation, enabling the transformer to support different load characteristics and system designs effectively.
Another important specification of this transformer is its compatibility with both 50Hz and 60Hz power systems. The transformer is engineered to operate efficiently at 50Hz, making it suitable for regions that follow this standard frequency. Additionally, the design can accommodate 60Hz transformers, which are prevalent in other parts of the world. This frequency adaptability makes the Oil Immersed Transformer a globally viable solution, capable of meeting international standards and operational requirements.
For applications requiring specific capacity, the transformer is available in various sizes, including the popular transformer 200kva rating. This capacity is widely used in commercial and industrial settings, providing a reliable power transformation solution that balances cost and performance. The 200kva rating ensures the transformer can handle substantial loads, supporting critical operations without interruption or overheating. Coupled with oil immersion cooling, this capacity delivers excellent efficiency and durability.
Customization options extend beyond voltage and connection configurations. Customers can specify various design parameters to align the transformer with their unique operational environments. This includes adjustments to physical dimensions, insulation class, and additional protective features. Such customization ensures that the transformer not only meets electrical specifications but also complies with safety regulations and environmental considerations.
In summary, the Oil Immersed Transformer offers a comprehensive package of reliability, efficiency, and flexibility. Its oil immersion cooling method guarantees superior thermal management, while the customizable voltage ratings and connection group labels like Yyn0 and Dyn11 provide adaptability for diverse applications. Operating effectively at both 50Hz and 60Hz frequencies and available in capacities like the transformer 200kva, it is well suited to meet the demands of modern power distribution networks worldwide. Whether for industrial plants, utility substations, or commercial buildings, this transformer delivers dependable performance and long-term operational excellence.
