Product Description

Product introduction

At Dongliang Electric Co., Ltd., we proudly present our remarkable three-phase oil-immersed power transformers, expertly engineered to function within an impressive rated voltage range of 10-35kV. These transformers are a testament to precision craftsmanship, serving an extraordinary spectrum of industries such as petroleum, metallurgy, chemical, textile, and light industry. Designed to excel in challenging environments with high dust concentrations, they deliver unmatched performance and superior reliability. With these extraordinary features, our transformers consistently surpass the stringent demands of various enterprises, offering nothing less than excellence.
Capacity Range 30-2500kVA

Meticulously engineered for peak performance, our product promises exceptional efficiency with minimal energy loss while maintaining impressively low noise levels. It boasts superior internal heat dissipation and strong anti-short circuit capabilities, ensuring reliable operation and exceptional durability. By minimizing both no-load and load loss, this transformer not only guarantees a maintenance-free experience but also establishes itself as an invaluable asset to your power solutions.

Our cutting-edge energy-saving, energy-efficient secondary-class oil-immersed transformer embodies our unwavering commitment to innovation. By integrating advanced materials with pioneering technologies and a seamless fusion of independent innovation and technology adoption, we have optimized the core and coil designs. This revolutionary approach significantly reduces no-load loss and noise, showcasing the remarkable achievements of our self-engineered products.

 

Oil-immersed transformers offer a plethora of advantages, such as excellent heat dissipation capabilities that ensure continuous and stable operation. With outstanding insulation and high reliability, these transformers enable effortless voltage adjustments for various electrical requirements. Their well-established technology and cost-effectiveness make them the perfect choice for a wide range of applications.

Iron Core: Our innovative iron core, crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, heralds a new era of efficiency. This fully oblique jointed iron core, with its multi-stepped section design, guarantees uniformity across the iron yoke and core, greatly enhancing overall performance and efficiency.

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

Safety Protection Device: Our transformers, with capacities ranging from 30 to 2000kVA, are equipped with crucial safety features like a pressure relief valve. Furthermore, a gas relay with alarm and trip terminals can be installed according to user requirements, significantly enhancing safety and operational dependability.
