By markedly reducing both no-load and load loss, this transformer ensures dependable operation and promises longevity. Moreover, it provides a maintenance-free experience, positioning itself as a vital asset for your power solutions.

Positioned at the forefront of technology, this state-of-the-art energy-saving, energy-efficient secondary-class oil-immersed transformer is a testament to our unwavering commitment to innovation. By merging pioneering materials with groundbreaking technologies, along with a harmonious blend of independent innovation and technology adoption, we have optimized the core and coil structures. This revolutionary approach significantly reduces no-load loss and noise, underscoring the extraordinary outcomes of our self-developed products.

 

Oil-immersed transformers offer a wealth of benefits, including superior heat dissipation capabilities that ensure the continuous and stable operation. Known for their exceptional insulation and high reliability, these transformers facilitate effortless voltage adjustments to accommodate a variety of electrical requirements. Their mature technology and cost-effectiveness render them the ideal choice for a multitude of applications.

Iron Core: Our state-of-the-art iron core, crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, heralds a new era of innovation. This fully oblique jointed iron core, featuring a multi-stepped section design, ensures uniformity throughout the iron yoke and core, significantly enhancing efficiency and performance.

Winding: Our meticulously engineered windings are equipped with corrugated oil passages and employ 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 enables seamless voltage alterations following a power supply interruption, ensuring unmatched adaptability.

Safety Protection Device: Our transformers, with capacities ranging from 30 to 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, enhancing safety and operational reliability.
