Product Description

Energy-saving and highly efficient, our secondary-class oil-immersed transformer represents the pinnacle of innovation at Global Power Equipment (Xuzhou) Co., Ltd. This state-of-the-art transformer is the result of extensive research and development in new materials and cutting-edge technology. By optimizing and innovatively designing the core and coil structure, we have successfully minimized no-load loss and noise, creating a superior, self-developed product for modern energy needs.

Oil-immersed transformers bring a host of remarkable advantages. They excel in heat dissipation, ensuring the stable operation of the transformer under various conditions. With outstanding insulation performance and high reliability, these transformers are easy to adjust for different voltage requirements. Furthermore, their mature technology ensures cost-effective solutions for diversified electricity needs.

Iron Core: Crafted from high-permeability, grain-oriented, cold-rolled silicon steel sheets, our iron core is at the forefront of design. Featuring a fully oblique jointed construction, the core exhibits a multi-stepped section, ensuring uniformity between the iron yoke and the core itself for unparalleled performance.

Winding: Utilizing a corrugated oil passage and eliminating immersion paint processes, our windings are secured with tightening belts for enhanced stability. The concentric coil design includes high-voltage winding taps, linked to the tap changer for effortless voltage adjustments. The switch, conveniently mounted on the box cover, allows for voltage changes post power cut-off, ensuring seamless operational flexibility.

Safety Protection Device Our transformers, ranging from 30-2000kVA, come equipped with a pressure relief valve as standard. Additionally, a gas relay featuring both alarm and trip terminals can be installed to meet specific user requirements, offering an extra layer of safety.

Oil Temperature Measuring Device: Each transformer includes a glass thermometer tube holder, strategically positioned at the top of the oil tank and extending 120±10 mm into the oil for precise temperature monitoring. Transformers between 1000-2000kVA are also equipped with an outdoor signal thermometer to ensure accurate and reliable temperature readings.
