Product Description

Our innovative and energy-efficient secondary-class oil-immersed transformer is an epitome of advanced engineering and cutting-edge technology. By harnessing new materials and pioneering techniques, we have optimized the core and coil structure to significantly reduce no-load loss and noise, delivering an outstanding product that combines independent innovation and technological integration.

Oil-immersed transformers boast numerous advantages. They excel in heat dissipation, ensuring stable operation; offer superior insulation and high reliability; allow for easy voltage adjustment to meet diverse electrical needs; and benefit from mature technology, making them cost-effective solutions.

Iron Core: Crafted from high permeability, grain-oriented cold-rolled silicon steel sheets, the iron core represents a new era in core technology. Featuring a fully oblique jointed design and a multi-stepped cross-section, both the iron yoke and iron core are meticulously engineered to ensure uniform cross-sectional areas.

Winding: The winding structure utilizes corrugated oil passages and a no-immersion paint process, with a tightening belt for added security. The concentric coil design includes high-voltage windings with taps aligned to specific voltage requirements, connected to a tap changer mounted on the box cover. Voltage adjustments can be made easily after cutting off the power supply.

Safety protection device The transformer, ranging from 30-2000kVA, is equipped with a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed based on user specifications.

Oil temperature measuring device: For precise temperature monitoring, the transformer features a glass thermometer tube holder at the top of the oil tank, extending 120±10 mm into the oil. Models ranging from 1000-2000kVA are equipped with an outdoor signal thermometer for enhanced monitoring capabilities.
