Our product, crafted with an unwavering commitment to superior excellence, ensures optimal efficiency with minimal energy losses, while maintaining impressively low noise levels. It features outstanding internal heat dispersion capabilities and robust anti-short circuit characteristics. By significantly decreasing both no-load and load loss, this transformer promises reliable operation and long-term durability. Furthermore, it offers a maintenance-free solution, establishing itself as an indispensable asset for your energy needs.

At the cutting edge of technology, this advanced energy-saving, energy-efficient secondary-class oil-immersed transformer exemplifies our relentless pursuit of innovation. By integrating pioneering materials with innovative technologies, paired with a perfect fusion of independent innovation and technology adoption, we have optimized the core and coil configurations. This groundbreaking strategy markedly reduces no-load loss and noise, spotlighting the exceptional results of our proprietary products.

 

Oil-immersed transformers provide a multitude of advantages, including exceptional heat dissipation capabilities that assure continuous and stable operation. Renowned for their outstanding insulation and reliability, these transformers enable seamless voltage adjustments to meet diverse electrical needs. Their mature technology and cost-effectiveness make them the perfect choice for numerous applications.

Iron Core: Our cutting-edge iron core, constructed from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, marks a new era of innovation. This fully oblique jointed iron core, featuring a multi-stepped sectional design, ensures uniformity across the iron yoke and core, significantly boosting efficiency and performance.

Winding: Our precisely engineered windings are equipped with corrugated oil passages and apply a no immersion paint process, secured with a tightening belt for enhanced stability. The concentric coil design incorporates high-voltage windings with taps for precise voltage adjustments, accessible via a tap changer mounted on the box cover, enabling seamless voltage alterations following a power supply interruption, ensuring unmatched adaptability.

Safety Protection Device: Our transformers, with capacities ranging from 30 to 2000kVA, are fitted with crucial safety features such as a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed according to user specifications, enhancing safety and operational dependability.

Apply	Mines, oil fields, subways, power plants, schools, hospitals, commercial centers, high-rise buildings
Installation height	The altitude does exceed 1000m
The waveform of the power supply voltage	similar to a sine wave

Oil Temperature Measuring Device: Each transformer is equipped with a strategically placed glass thermometer in a tube holder atop the oil tank, extending 120±10 mm into the oil. For transformers within the 1000-2000kVA range, an outdoor signal thermometer is included, offering precise and reliable temperature monitoring.
