Capacity Range 30-2500kVA

Crafted with an unwavering focus on precision, our product promises peak efficiency with minimal energy loss, alongside impressively low noise levels. It excels in internal heat dissipation and boasts robust anti-short circuit properties. By significantly reducing both no-load and load loss, this transformer ensures dependable operation and promises longevity. Additionally, it offers a maintenance-free experience, establishing itself as an indispensable component for your power solutions.

At the cutting-edge of technology, this advanced energy-saving, energy-efficient secondary-class oil-immersed transformer exemplifies our steadfast dedication to innovation. By integrating pioneering materials with revolutionary technologies, alongside a harmonious integration of independent innovation and technology adoption, we have optimized the core and coil structures. This groundbreaking approach remarkably decreases no-load loss and noise, illustrating the extraordinary results of our self-developed products.

 

Oil-immersed transformers provide a multitude of advantages, including exceptional heat dissipation capabilities that ensure continuous and stable operation. Renowned for their superior insulation and high reliability, these transformers allow for effortless voltage adjustments to meet various electrical requirements. Their established technology and cost-effectiveness make them the perfect choice for numerous applications.

Iron Core: Our state-of-the-art iron core, constructed from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, ushers in a new era of innovation. This fully oblique jointed iron core, featuring a multi-stepped section design, ensures uniformity throughout the iron yoke and core, significantly boosting efficiency and performance.

Winding: Our expertly crafted windings feature corrugated oil passages and employ 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, accessible via a tap changer mounted on the box cover. This facilitates seamless voltage transitions following a power supply interruption, ensuring adaptability that is unmatched.

Safety Protection Device: Our transformers, with capacities spanning from 30 to 2000kVA, come equipped with vital safety features such as a pressure relief valve. Furthermore, a gas relay with alarm and trip terminals can be installed according to user requirements, enhancing safety and operational reliability.
