Additionally, it offers a maintenance-free experience, making it an indispensable asset for your power solutions.

At the pinnacle of technology, this state-of-the-art energy-saving, energy-efficient secondary-class oil-immersed transformer embodies our unwavering commitment to innovation. By integrating pioneering materials and groundbreaking technologies, along with a harmonious blend of independent innovation and technology adoption, we have optimized the core and coil structures. This groundbreaking approach significantly reduces no-load loss and noise, emphasizing the extraordinary efficiency of our self-developed products.

 

Oil-immersed transformers provide a wealth of benefits, including superior heat dissipation capabilities that ensure continuous, stable operation. Known for their exceptional insulation and high reliability, these transformers enable effortless voltage adjustments for various electrical requirements. Their mature technology and cost-effectiveness make them the perfect choice for a multitude of applications.

Iron Core: Our cutting-edge iron core, crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, heralds a new era of innovation. This fully oblique jointed iron core, with its multi-stepped section design, ensures uniformity throughout the iron yoke and core, significantly enhancing efficiency and performance.

Winding: Our meticulously engineered windings feature corrugated oil passages and utilize 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. This facilitates seamless voltage alterations following a power supply interruption, ensuring unmatched adaptability.

Safety Protection Device: Our transformers, with capacities ranging from 30 to 2000kVA, come equipped with essential safety features like a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed as per user requirements, enhancing safety and operational reliability.
