Product Description

Our energy-efficient, secondary-class oil-immersed transformer is a marvel of modern engineering. Developed through rigorous research and the integration of cutting-edge materials and technologies, this transformer stands as a testament to our commitment to innovation. By optimizing the core and coil structure, we've significantly reduced no-load loss and noise, offering an unparalleled product designed for maximum efficiency and performance.

Oil-immersed transformers come with a host of unparalleled benefits. They boast exceptional heat dissipation capabilities, ensuring a stable operation. Their superior insulation performance guarantees high reliability, and their design allows for easy voltage adjustments to meet diverse electricity demands. Additionally, their mature technology and cost-efficiency make them an ideal choice for various applications.

Iron Core: Crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, the iron core is a pioneering innovation. The full oblique-jointed design features a multi-stepped core section, ensuring uniform sections between the iron yoke and core, thereby enhancing the overall performance and efficiency of the transformer.

Winding: Our windings feature corrugated oil passages and eschew immersion paint processes for enhanced durability. The concentric coil design ensures optimal performance, with high-voltage windings equipped with taps to meet varying voltage requirements. The tap changer, mounted on the box cover, allows for easy voltage adjustments after power disconnection.

Safety Protection Device For transformers ranging from 30-2000 kVA, we include a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed as per user specifications, ensuring comprehensive safety and protection.

Oil Temperature Measuring Device: Our transformers are equipped with a glass thermometer tube holder, positioned at the top of the oil tank and extending 120±10 mm into the oil. For units between 1000-2000 kVA, an outdoor signal thermometer is provided, ensuring accurate and reliable temperature monitoring.
