Product Description

25kv to 13.8kv Oil Immersed Electrical Transformer

Our energy-saving, secondary-class oil-immersed transformer represents the pinnacle of our research and application of cutting-edge materials and technologies. By seamlessly combining independent innovation with technology introduction, we have meticulously optimized and innovatively designed the core and coil structure. This innovative approach significantly reduces no-load loss and noise, resulting in a self-developed product that sets new standards in efficiency and performance.

Oil-immersed transformers offer a multitude of benefits. They excel in heat dissipation, ensuring the transformer's stable operation. Boasting exceptional insulation and high reliability, these transformers can easily adapt to various voltage requirements, making them versatile for different electrical needs. With mature technology and cost-effectiveness, oil-immersed transformers are a trusted choice in the industry.

Iron Core: Crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, the iron core represents a new generation of core design. The full oblique-jointed iron core features a multi-stepped section, ensuring equal sections for the iron yoke and iron core, enhancing overall efficiency and performance.

Winding: The winding utilizes a corrugated oil passage without immersion paint processes and is secured with tightening belts. Designed as concentric coils, the high-voltage winding features taps that correspond to the tapping voltage requirements, which are directed to the tap changer. The switch, mounted on the box cover, allows for voltage adjustments post power supply cut-off.

Safety protection device For optimum safety, our 30-2000kVA transformers come equipped with a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed upon user request, ensuring maximum safety and operational efficiency.

Oil temperature measuring device: The transformer includes a tube holder with a glass thermometer, strategically placed at the top of the oil tank and extending 120±10 mm into the oil. For transformers between 1000-2000kVA, an outdoor signal thermometer is provided, ensuring accurate temperature monitoring.
