Product Description

Our energy-saving, energy-efficient secondary-class oil-immersed transformer is the pinnacle of our innovative efforts at Global Power Equipment (Xuzhou) Co., Ltd. Through extensive research, the application of cutting-edge materials and technologies, and a blend of independent innovation and technological integration, we have optimized and innovatively designed the core and coil structure. This has resulted in a significant reduction of no-load losses and noise, showcasing our sophisticated self-developed product.

Oil-immersed transformers come with a plethora of benefits. They boast excellent heat dissipation capabilities, ensuring the stable operation of the transformer. Their superior insulation performance and high reliability are noteworthy. Furthermore, the ease of voltage adjustment allows these transformers to cater to a variety of electrical needs. With mature technology and cost-effectiveness, oil-immersed transformers stand out as a prime choice in the industry.

Iron Core: Crafted from high permeability magnetic grain-oriented cold-rolled silicon steel sheets, the iron core is a state-of-the-art design. Our unique fully oblique-jointed iron core features a multi-stepped step section, ensuring that the iron yoke and the core maintain equal sections. This innovative approach enhances the overall efficiency and performance of the transformer.

Winding: Our windings adopt a corrugated oil passage design and eschew the immersion paint process, instead utilizing a tightening belt for secure binding. The concentric coil design ensures optimal performance. The high-voltage winding includes taps that meet specific tapping voltage requirements, connected to the tap changer. The switch, mounted on the box cover, allows for voltage adjustments post power cutoff, ensuring flexibility and adaptability.

Safety Protection Device Safety is paramount with our 30-2000kVA transformers, which come equipped with a pressure relief valve. Additionally, a gas relay with an alarm and trip terminal can be installed based on user requirements, providing enhanced safety measures.

Oil Temperature Measuring Device: Our transformers feature a glass thermometer tube holder, positioned at the top of the oil tank and extending into the oil by 120±10 mm, ensuring accurate temperature measurement. For 1000-2000kVA transformers, an outdoor signal thermometer is provided, ensuring precise and reliable temperature monitoring.
