Our meticulously engineered product sets the benchmark for performance, characterized by exceptional efficiency, minimized energy loss, and impressively low noise emissions. It boasts superior internal heat dissipation and fortifies against short circuits, ensuring low no-load and load loss. With such dependability, expect an extended lifespan and a virtually maintenance-free operational experience, making it your trusted partner in power management.

Behold our energy-conserving, efficiency-maximized secondary-class oil-immersed transformer, a testament to Dongliang Electric Co., Ltd.'s unwavering commitment to innovation. By integrating groundbreaking materials, state-of-the-art technologies, and a harmonious blend of independent innovation with technological advancements, we have revolutionized core and coil structures. Witness the remarkable reduction in no-load loss and noise, embodying the success of our self-developed marvels.

 

Oil-immersed transformers are synonymous with unparalleled benefits, featuring extraordinary heat dissipation capabilities that guarantee steadfast performance. Renowned for exceptional insulation and reliability, they facilitate seamless voltage adjustments to accommodate diverse electrical needs. Their matured technology and cost-efficiency make them the quintessential choice for a myriad of applications.

Iron Core: Constructed with high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, our next-generation iron core is a masterpiece. The full oblique jointed design with a multi-stepped section ensures uniformity across the iron yoke and core, significantly enhancing efficiency and optimizing performance like never before.

Winding: Our windings are a marvel of engineering, featuring corrugated oil passages and a no immersion paint process, secured with a precision tightening belt for unparalleled stability. The concentric coil design, with high-voltage windings equipped with taps for meticulous voltage adjustments, is accessible via a tap changer on the box cover, facilitating seamless voltage changes post power supply interruption.

Safety Protection Device: Our transformers, with a capacity range of 30-2000kVA, are fortified with advanced safety features such as a pressure relief valve. A gas relay, complete with alarm and trip terminals, can be tailored to user specifications, enhancing safety and operational integrity with peace of mind.
