Engineered with precision for peak excellence, our product guarantees high efficiency with minimal energy loss, complemented by impressively low noise output. It boasts superior internal heat dissipation capabilities and robust anti-short circuit properties. By effectively reducing both no-load and load loss, this transformer ensures reliable operation and promises an extended lifespan. Furthermore, it delivers a maintenance-free experience, establishing itself as an indispensable asset for your power solutions.

This state-of-the-art energy-saving, energy-efficient secondary-class oil-immersed transformer epitomizes our commitment to innovation. Through the integration of advanced materials and pioneering technologies, along with a harmonious blend of independent innovation and technology adoption, we have optimized the core and coil structures. This groundbreaking approach significantly diminishes no-load loss and noise, underscoring the extraordinary results of our self-developed products.

 

Oil-immersed transformers offer a vast array of benefits, including superior heat dissipation capabilities that ensure continuous and stable operation. Renowned for their exceptional insulation and high reliability, these transformers allow effortless voltage adjustments to suit a variety of electrical needs. Their mature technology and cost-effectiveness make them the ideal choice for numerous applications.

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

Winding: Our meticulously engineered windings feature corrugated oil passages and a no immersion paint process, secured with a tightening belt for increased 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 allows seamless voltage alterations after power supply interruption, ensuring unmatched adaptability.

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