Product Description:

The Oil Immersed Transformer is a highly reliable and efficient electrical device designed for a variety of power distribution and transmission applications. As a three-phase transformer, it is engineered to handle substantial electrical loads, making it a crucial component in modern power systems. This transformer is distinguished by its oil immersion cooling method, which enhances its operational stability and longevity by effectively dissipating heat generated during operation.

One of the defining features of this transformer is its use of transformer Oxygen-Free Copper for its windings. This high-purity copper material significantly improves electrical conductivity and reduces energy losses, contributing to superior performance and energy efficiency. The transformer is built as a double-winding transformer, which means it has two separate windings—the primary and secondary—allowing for versatile voltage transformation and ensuring optimal performance across various usage scenarios.

In terms of connection configurations, the Oil Immersed Transformer offers multiple options including Yd11, Yyn0, and Dyn11. These connection symbols represent different winding arrangements and phase shifts, providing flexibility for integration into diverse electrical networks. The choice of connection type allows the transformer to adapt to specific system requirements and enhances its compatibility with a wide range of power distribution setups.

The cooling class of the transformer is another critical aspect that underscores its adaptability and efficiency. It supports several cooling classes such as ONAN (Oil Natural Air Natural), ONAF (Oil Natural Air Forced), OFAF (Oil Forced Air Forced), and OFWF (Oil Forced Water Forced). Each cooling class represents a different method of heat dissipation, catering to various environmental conditions and load demands. ONAN cooling is typically used for standard load conditions, while ONAF, OFAF, and OFWF cooling methods are employed for higher load capacities and more demanding operational environments, ensuring the transformer maintains optimal temperature levels and operational reliability.

The Oil Immersed Transformer is widely recognized as an American-Style transformer, known for its robust construction and adherence to stringent quality standards. This style of transformer is designed to meet the rigorous demands of the power industry, providing exceptional durability and performance.
