Featuring outstanding internal heat dissipation and robust anti-short circuit capabilities, this transformer ensures reliable operation with minimal no-load and load loss. It promises a prolonged lifespan and a maintenance-free experience, making it an indispensable asset for your power solutions.

This state-of-the-art energy-saving, energy-efficient secondary-class oil-immersed transformer epitomizes our dedication to innovation. By incorporating advanced materials, pioneering technologies, and a harmonious blend of independent innovation with technology adoption, we've finely optimized and transformed the core and coil structures. This progress dramatically reduces no-load loss and noise, showcasing the impressive outcomes of our self-developed products.

 

Oil-immersed transformers come with a wide array of benefits, including superior heat dissipation capabilities that guarantee consistent and stable operation. Celebrated for their excellent insulation and high reliability, these transformers enable effortless voltage adjustments to meet diverse electrical needs. Their mature technology and cost-effectiveness render them an ideal choice across a multitude of applications.

Iron Core: Our cutting-edge iron core, ingeniously crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, heralds a new era of innovation. This full oblique jointed iron core boasts a multi-stepped section design, ensuring uniformity throughout the iron yoke and the core, significantly elevating efficiency and performance.

Winding: Our meticulously designed windings feature corrugated oil passages and a no immersion paint process, secured with a tightening belt for enhanced stability. The concentric coil design integrates high-voltage windings with taps for precise voltage adjustments, accessible through 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 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 requirements, elevating safety and operational integrity.
