Product Description

Our energy-saving, energy-efficient, secondary-class oil-immersed transformer is a pinnacle of innovation at Global Power Equipment (Xuzhou) Co., Ltd. By leveraging cutting-edge materials and groundbreaking technologies, we have meticulously engineered the core and coil structure. The result is a transformer that significantly reduces no-load loss and noise, epitomizing our dedication to excellence and sustainability.

Oil-immersed transformers are renowned for their exceptional advantages. They boast superior heat dissipation capabilities, ensuring the stable operation of the transformer under varying loads. With excellent insulation properties and high reliability, these transformers can effectively adjust voltage to meet diverse electrical demands. Moreover, the technology is well-developed, making it a cost-effective solution.

Iron Core: Crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, the iron core represents the latest innovation in core technology. Featuring a fully oblique jointed structure with a multi-stepped section, the core and yoke maintain equal sections, ensuring optimal performance and efficiency.

Winding: Utilizing a corrugated oil passage and a no-immersion paint process, the windings are meticulously secured with a tightening belt. These concentric coils include high-voltage windings with taps tailored to specific voltage requirements. The tap changer is conveniently mounted on the box cover, allowing for easy voltage adjustments once the power supply is disconnected.

Safety Protection Device Our 30-2000kVA transformers are equipped with a state-of-the-art pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed upon user request, enhancing operational safety.

Oil Temperature Measuring Device: The transformer features a glass thermometer tube holder, positioned at the top of the oil tank and extending 120±10 mm into the oil. For 1000-2000kVA transformers, an outdoor signal thermometer is included, ensuring precise temperature monitoring.
