Product Description

Introducing our energy-saving, highly efficient, secondary-class oil-immersed transformer—a testament to our dedication to research, innovation, and technological advancement. By harnessing new materials and methodologies, we've engineered this transformer to optimize core and coil structures, significantly reducing no-load losses and noise, and delivering unparalleled performance.

Our oil-immersed transformers boast exceptional benefits: superior heat dissipation ensuring stable operation, outstanding insulation performance enhancing reliability, and easy voltage adjustments to meet diverse electrical demands. Coupled with mature technology, these transformers offer a cost-effective solution for a variety of applications.

Iron Core: Crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, our core represents a new era in transformer cores. Featuring a fully oblique, multi-stepped design, both the iron yoke and the core maintain equal sections, enhancing overall efficiency and performance.

Winding: Our windings are meticulously designed with corrugated oil passages and employ a no immersion paint process, secured with tightening belts. The concentric coil design, complete with high-voltage taps, ensures precise voltage adjustments via an accessible tap changer mounted on the box cover.

Safety protection device Our transformers, ranging from 30-2000kVA, incorporate a pressure relief valve as standard. Additionally, a gas relay with alarm and trip terminals can be installed upon user request, ensuring maximum operational safety.

Oil temperature measuring device: Each transformer is equipped with a glass thermometer tube holder, strategically placed at the top of the oil tank and extending 120±10 mm into the oil. For models ranging from 1000-2000kVA, an outdoor signal thermometer is included for precise temperature monitoring.
