These transformers are the quintessential choice for a broad spectrum of industries such as petroleum, metallurgy, chemical, textile, and light industry. Designed to thrive in high-dust environments, they deliver exceptional performance and steadfast reliability, satisfying the rigorous demands of various enterprises with ease.
Capacity Range 30-2500kVA

Our product is a masterpiece of engineering, offering remarkable efficiency, minimal energy loss, and notably low noise emissions. It showcases superior internal heat dissipation and robust anti-short circuit capabilities. With its minimal no-load and load loss, this transformer assures dependable operation, an extended lifespan, and a maintenance-free experience, proving itself to be an essential element of your power solutions.

This cutting-edge, energy-saving, and energy-efficient secondary-class oil-immersed transformer is a testament to our dedication to innovation. By incorporating advanced materials, avant-garde technologies, and a blend of independent innovation with technology adoption, we have revolutionized the core and coil structures. This enhancement significantly curtails no-load loss and noise, showcasing the remarkable achievements of our self-initiated products.

 

Oil-immersed transformers provide a multitude of benefits, including exceptional heat dissipation capabilities that guarantee consistent and stable operation. Celebrated for their outstanding insulation and high dependability, these transformers offer seamless voltage adjustments to cater to diverse electrical demands. Their mature technology and cost-efficiency render them an ideal selection for a wide array of applications.

Iron Core: Our state-of-the-art iron core, fashioned from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, heralds a new epoch of innovation. This fully oblique jointed iron core boasts a multi-stepped section design, ensuring uniformity throughout the iron yoke and the core itself, which significantly elevates efficiency and performance.

Winding: Our meticulously engineered windings feature corrugated oil passages and a no immersion paint process, secured with a tightening belt to enhance stability. The concentric coil design is equipped with high-voltage windings that include taps for precise voltage adjustments, accessible via a tap changer mounted on the box cover, facilitating smooth voltage changes post power supply interruption.

Safety Protection Device: Our transformers, with a capacity spectrum of 30-2000kVA, are fitted with crucial safety elements such as a pressure relief valve. Furthermore, a gas relay with alarm and trip terminals can be installed according to user specifications, boosting safety and operational integrity.

Apply	Mines, oil fields, subways, power plants, schools, hospitals, commercial centers, high-rise buildings
Installation height	The altitude does exceed 1000m
