Product Description

Our energy-efficient, secondary-class Step Down Oil Immersed Power Transformer exemplifies cutting-edge innovation at Global Power Equipment (Xuzhou) Co., Ltd. By integrating new materials and advanced technology alongside independent innovation, we’ve pioneered an optimized core and coil structure. This breakthrough design significantly diminishes no-load losses and noise, establishing a new standard in transformer performance.

Oil-immersed transformers are renowned for their numerous benefits. They boast outstanding heat dissipation capabilities, ensuring stable and efficient transformer operation. Additionally, they offer superior insulation and reliability. With easy voltage adjustments, these transformers can accommodate diverse electrical requirements. Their well-established technology and cost-effectiveness further enhance their appeal.

Iron Core: Crafted from high permeability, grain-oriented cold-rolled silicon steel sheets, the iron core stands as a pinnacle of engineering. This innovative, fully oblique jointed core features a multi-stepped section design, ensuring uniform sections for both the iron yoke and the core itself.

Winding: Our windings utilize a corrugated oil passage, eliminating the need for immersion paint processes. The windings are secured with a tightening belt and feature concentric coil designs. The high-voltage winding includes taps that align with tapping voltage requirements, leading to a tap changer mounted on the box cover. Voltage adjustments can be made easily by cutting off the power supply.

Safety Protection Device For optimal protection, transformers ranging from 30-2000kVA are equipped with pressure relief valves. Additionally, a gas relay with alarm and trip terminals can be installed based on user requirements.

Oil Temperature Measuring Device: The transformer includes 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 also provided for enhanced temperature monitoring.
