Our meticulously engineered product sets the benchmark for superior performance, characterized by exceptional efficiency, minimal energy dissipation, and commendably low noise levels. It is built to ensure outstanding internal heat dissipation and robust anti-short circuit capabilities. With remarkably low no-load and load losses, this transformer guarantees dependable operation, an extended lifespan, and a maintenance-free experience, establishing itself as a trusted and invaluable component for your power infrastructure.

This energy-saving, highly efficient secondary-class oil-immersed transformer epitomizes our company's unwavering commitment to innovation. By harnessing new materials, pioneering technologies, and a harmonious blend of independent innovation with technology introduction, we have optimized and revolutionized the core and coil structures. This advancement significantly reduces no-load loss and noise, celebrating the achievements of our self-developed products, making it a leading-edge solution in the industry.

 

Oil-immersed transformers offer a myriad of advantages, notable for their exceptional heat dissipation capabilities which ensure unwavering stability in operation. These transformers are lauded for their superior insulation and high dependability. They facilitate easy voltage adjustments, accommodating diverse electrical requirements, while their matured technology and cost-effectiveness render them an exemplary choice for a wide range of applications, solidifying their status as a go-to solution in the market.

Iron Core: The core, crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, represents a revolutionary new generation of iron cores. The fully oblique jointed iron core, with its multi-stepped section design, ensures uniformity across both the iron yoke and the core itself, dramatically enhancing efficiency and performance, setting a new standard in transformer design.

Winding: Our windings feature innovative corrugated oil passages and a no immersion paint process, secured with a tightening belt for utmost stability. The concentric coil design incorporates high-voltage windings equipped with taps for precise voltage adjustments. These can be seamlessly accessed via a tap changer mounted on the box cover, facilitating effortless adjustments to the tap voltage following any power supply interruption, ensuring peak performance and adaptability.

Safety Protection Device: Our transformers, with capacities ranging from 30-2000kVA, are equipped with cutting-edge safety features such as a pressure relief valve. Additionally, a gas relay featuring alarm and trip terminals can be installed according to user requirements, enhancing the safety and operational integrity of the transformer, ensuring peace of mind and reliable operation under all conditions.
