With exceptional internal heat management and robust anti-short circuit features, it showcases minimal no-load and load loss, ensuring reliable operation, extended service life, and a virtually maintenance-free experience, establishing itself as an essential component for your power solutions.

Our state-of-the-art energy-saving, energy-efficient secondary-class oil-immersed transformer epitomizes our dedication to innovation. By harnessing advanced materials, pioneering technologies, and a fusion of self-driven innovation with technology adaptation, we've optimized the core and coil structures. These enhancements drastically reduce no-load loss and noise, underscoring the impressive achievements of our self-developed products.

 

Oil-immersed transformers offer an impressive array of benefits, including superior heat dissipation capabilities that ensure consistent and stable operation. Celebrated for their excellent insulation and high reliability, these transformers facilitate effortless voltage adjustments, accommodating a diverse spectrum of electrical requirements. Their matured technology and cost-effectiveness render them an ideal selection for countless applications.

Iron Core: Our innovative iron core, crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, signifies a new era of technological advancement. This full oblique jointed iron core with a multi-stepped section design ensures uniformity throughout the iron yoke and core, significantly boosting efficiency and performance.

Winding: Our meticulously engineered windings feature corrugated oil passages and a no immersion paint process, reinforced with a tightening belt for superior 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, facilitating seamless voltage changes post power supply interruption.

Safety Protection Device: Our transformers, with a capacity range of 30-2000kVA, are fortified with essential safety features such as a pressure relief valve. Additionally, a gas relay complete with alarm and trip terminals can be installed according to user requirements, enhancing safety and operational integrity.
