They are the perfect solution tailored to meet the uncompromising demands of industries such as petroleum, metallurgy, chemical, textile, and light industry. Designed with precision for environments with high dust concentrations, these transformers guarantee optimal performance and unparalleled reliability, making them the ultimate choice for diverse enterprises.
Capacity Range 30-2500kVA

Crafted to deliver outstanding performance, our product features first-rate efficiency and minimal energy loss, coupled with remarkably low noise levels. It excels with superior internal heat dissipation and formidable anti-short circuit capabilities. Experience consistent operation, an extended lifespan, and a maintenance-free experience with low no-load and load loss, ensuring it stands as a reliable powerhouse for all your electrical needs.

Embodying cutting-edge innovation, this energy-saving, energy-efficient secondary-class oil-immersed transformer is a proud testament to our commitment to technological advancement. By integrating new materials and advanced technologies with a balance of independent innovation and technology introduction, we've optimized the core and coil structures. This breakthrough dramatically reduces no-load loss and noise, epitomizing the excellence of our self-developed products.

 

Oil-immersed transformers are exceptional in offering superior heat dissipation capabilities, ensuring stable and reliable operation. Known for outstanding insulation and high reliability, they accommodate easy voltage adjustments to meet myriad electrical requirements. Their matured technology coupled with cost-effectiveness makes them the perfect choice for a wide range of applications.

Iron Core: Our iron core, constructed from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, represents the pinnacle of modern design. The full oblique jointed iron core with a multi-stepped section design ensures uniformity across the iron yoke and core itself, boosting both efficiency and performance.

Winding: Our expertly crafted windings feature corrugated oil passages and a no immersion paint process, secured meticulously with a tightening belt for enhanced stability. The innovative concentric coil design includes high-voltage windings with taps for precise voltage adjustments, conveniently accessible via a tap changer mounted on the box cover, enabling seamless tap voltage changes post power supply interruption.

Safety Protection Device: Equipped with a range of safety features, our transformers (spanning 30-2000kVA) include a pressure relief valve for added protection. Additionally, a gas relay with alarm and trip terminals can be installed according to user specifications, significantly enhancing safety and operational integrity.
