It features exceptional internal heat dissipation and robust anti-short circuit properties. By significantly reducing no-load and load loss, this transformer ensures reliable and long-lasting operation, offering a maintenance-free experience and establishing itself as an indispensable asset for your power solutions.

At the cutting edge of technology, this advanced energy-saving and energy-efficient secondary-class oil-immersed transformer exemplifies our unwavering commitment to innovation. By integrating pioneering materials with groundbreaking technologies, we harmoniously blend independent innovation with technology adoption, optimizing the core and coil structures. This revolutionary approach significantly reduces no-load loss and noise, highlighting the extraordinary results of our self-developed products.

 

Oil-immersed transformers provide a multitude of advantages, from superior heat dissipation ensuring continuous and stable operation, to exceptional insulation and high reliability. These transformers allow effortless voltage adjustments for various electrical requirements. Their established technology and cost-effectiveness make them the perfect choice for numerous 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. Featuring a fully oblique jointed design with a multi-stepped section, it ensures uniformity throughout the iron yoke and core, significantly boosting efficiency and performance.

Winding: Our expertly engineered windings, equipped with corrugated oil passages, utilize a non-immersion paint process and are 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 on the box cover, allowing seamless voltage alterations post power supply interruption, ensuring unmatched adaptability.

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