Our transformers are a testament to engineering brilliance, achieving maximum efficiency with minimal energy loss and exceptionally low noise output. They feature superior internal heat dissipation and robust anti-short circuit capabilities. With reduced no-load and load loss, these transformers ensure reliable operation and an extended lifespan, offering a maintenance-free experience. An indispensable asset in your power solutions repertoire.

Our cutting-edge energy-saving and energy-efficient secondary-class oil-immersed transformer epitomizes our commitment to innovation. By integrating advanced materials and pioneering technologies, coupled with a synthesis of independent innovation and technology adoption, we've optimized the core and coil structures. This landmark advancement significantly diminishes no-load loss and noise, underlining the remarkable achievements of our self-developed products.

 

Oil-immersed transformers provide a multitude of advantages, including superior heat dissipation capabilities that ensure continuous and stable operation. Renowned for their excellent insulation and high reliability, these transformers facilitate effortless voltage adjustments to cater to diverse electrical requirements. Their mature technology and cost-effectiveness make them the ideal choice for a wide variety of applications.

Iron Core: Our cutting-edge iron core, crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, marks 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 boosting efficiency and performance.

Winding: Our masterfully designed windings boast corrugated oil passages and 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 on the box cover, enabling seamless voltage alterations post power supply interruption.

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