Product Description

Our energy-saving, energy-efficient secondary-class oil-immersed transformer is a product of Global Power Equipment (Xuzhou) Co., Ltd. It has been meticulously developed through extensive research, the application of advanced materials, cutting-edge technology, and a harmonious blend of independent innovation and technological integration. By optimizing and innovatively designing the core and coil structure, we have significantly reduced no-load loss and noise, making this transformer an exemplary model of self-developed excellence.

Oil-immersed transformers boast numerous advantages, such as superior heat dissipation that ensures the stable operation of the transformer. They also offer excellent insulation performance and high reliability. These transformers are designed to be easily adjustable to meet various voltage requirements, making them versatile and adaptable to different electricity needs. Furthermore, the technology underlying oil-immersed transformers is mature, resulting in a cost-effective solution.

Iron Core: Crafted from high permeability magnetic grain-oriented cold-rolled silicon steel sheets, the core of our transformer represents a new era of iron core technology. It features a fully oblique jointed design with a multi-stepped core section. This innovative construction ensures that the iron yoke and core sections are equal, enhancing overall performance and efficiency.

Winding: Our winding technology incorporates a corrugated oil passage and eliminates the need for an immersion paint process. Tightly bound with a securing belt, the concentric coils of the windings are engineered to meet high-voltage tapping requirements. These taps correspond to specific voltage needs and are connected to a tap changer. The switch, mounted on the box cover, allows for voltage adjustments post power cut-off, ensuring optimal performance.

Safety protection device : For transformers ranging from 30-2000kVA, we equip them with a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed based on user specifications, providing an extra layer of safety.

Oil temperature measuring device: Our transformer includes a specialized glass thermometer tube holder. Positioned at the top of the oil tank, the tube seat extends into the oil by 120±10 mm. For transformers from 1000-2000kVA, we provide an outdoor signal thermometer, ensuring precise and reliable temperature monitoring.
