Product Description

Liu Gao is a 33KV Series Oil immersed Distribution Transformer Suppliers, fully sealed oil-immersed distribution transformers, designed to meet and exceed the stringent standards set by the International Electrotechnical Commission (IEC), stands out for its exceptional performance. Distinguished by a core crafted from premium cold-rolled silicon sheets, adopting a full-miter non-puncture structure for enhanced durability, and featuring a coil composed of high-quality oxygen-free copper, these transformers offer optimal conductivity and efficiency. The choice of a radiator oil tank, available in either corrugated sheet or expansion type, further exemplifies the versatility and adaptability of these oil-immersed transformers, making them a noteworthy choice for various applications.


A distinctive advantage of the S9 series lies in its elimination of the need for an oil conservator. This design modification not only reduces the overall height of the oil-immersed transformer but also contributes to operational efficiency. Moreover, by preventing the transformer oil from coming into contact with air, the aging process of the oil is significantly slowed down. This crucial feature, coupled with the robust construction and sealed design of the oil-immersed transformer, translates to an extended service life, ensuring sustained reliability and performance over time.


The applications of this oil-immersed transformer product are diverse, making it a preferred choice for various settings, including urban power grid reconstruction, residential districts, factories, high-rise buildings, mining facilities, hotels, shopping malls, airports, railways, oil fields, wharves, highways, and numerous other outdoor environments. The S9 series, as a fully sealed oil-immersed transformer, stands as a reliable and adaptable solution for a wide range of power distribution needs in both urban and industrial contexts.
