Our product, crafted with an unwavering commitment to precision, achieves optimal efficiency with minimal energy loss and impressively low noise levels. It features exceptional internal heat dissipation and robust short-circuit resistance. By dramatically reducing both no-load and load loss, this transformer ensures dependable operation and prolonged longevity. It also offers a maintenance-free experience, establishing itself as an indispensable asset for your power solutions.

At the cutting edge of technology, this cutting-edge energy-saving, energy-efficient secondary-class oil-immersed transformer exemplifies our dedication to innovation. By integrating advanced materials with leading-edge technologies and seamlessly blending independent innovation with technology adoption, we have optimized the core and coil structures. This revolutionary advancement significantly diminishes no-load loss and noise, highlighting the remarkable results of our self-developed products.

 

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

Iron Core: Our cutting-edge iron core, fashioned 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, ensures uniformity throughout the iron yoke and core, significantly elevating efficiency and performance.

Winding: Our meticulously crafted windings are equipped with corrugated oil passages and utilize 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 mounted on the box cover. This allows for seamless voltage alterations following a power supply interruption, ensuring unparalleled adaptability.

Safety Protection Device: Our transformers, with capacities spanning from 30 to 2000kVA, are equipped with essential safety features, including a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed according to user requirements, enhancing both safety and operational reliability.
