Capacity Range 30-2500kVA

Experience unparalleled performance with our transformative product, engineered for exceptional efficiency and minimal energy loss. With its ultra-low noise levels, superior internal heat dissipation, and strong anti-short circuit capabilities, this transformer guarantees reliable operation. Enjoy the benefits of low no-load and load loss, resulting in a maintenance-free experience and a significantly extended lifespan, making it your go-to solution for consistent power needs.

Embrace the future with our energy-saving, secondary-class oil-immersed transformer, a true reflection of our passion for innovation. By integrating cutting-edge technology and pioneering materials, we've reimagined the core and coil designs, drastically reducing no-load loss and noise. This advancement embodies the success of our independently developed products, setting a new standard in efficiency and performance.

 

Dive into the world of oil-immersed transformers, celebrated for their outstanding heat dissipation that ensures unwavering stability. With unparalleled insulation and reliability, these transformers offer effortless voltage adjustments to meet a variety of electrical demands. Their proven technology and cost-effective nature make them the ultimate choice for diverse applications, ensuring value and operational excellence.

Iron Core: Our iron core represents the pinnacle of innovation, crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets. Featuring a full oblique jointed, multi-stepped section design, it ensures uniformity across the iron yoke and core, optimizing efficiency and performance like never before.

Winding: Our winding technology is a masterpiece of precision and stability. The use of corrugated oil passages along with a no immersion paint process, secured by a tightening belt, ensures robust performance. The concentric coil design, with high-voltage windings and adjustable taps, allows for precise voltage modifications via a tap changer on the box cover, facilitating smooth adjustments post-power interruption.

Safety Protection Device: Our transformers, spanning 30-2000kVA, are fortified with advanced safety features such as a pressure relief valve. Tailored to user specifications, a gas relay with alarm and trip terminals can also be integrated, enhancing the safety and integrity of operations to the highest level.
