Product Description

Our energy-efficient, secondary-class oil-immersed transformer exemplifies the pinnacle of modern innovation and technological advancement. Meticulously crafted through a blend of new materials, cutting-edge techniques, and a harmonious fusion of independent innovation and technology introduction, this transformer boasts exceptional core and coil structure optimization. The result? Significantly reduced no-load loss and noise, all encapsulated in a product of our own groundbreaking development.

Oil-immersed transformers are replete with numerous benefits. They excel in heat dissipation, ensuring the transformer's stable and reliable operation. Renowned for their superior insulation performance and high reliability, they easily adapt to diverse voltage needs, thanks to their adjustable voltage features. Moreover, this mature technology offers a cost-effective solution, making it a prudent choice for various applications.

Iron Core: Crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, our iron core embodies the latest in iron core design. Featuring a fully oblique jointed, multi-stepped section, the iron core and yoke maintain equal section dimensions, enhancing overall performance.

Winding: Our winding design incorporates corrugated oil passages and eschews immersion paint processes, utilizing tightened belts for secure binding. The concentric coil windings come equipped with high-voltage taps tailored to meet specific voltage requirements. These taps are seamlessly integrated with the tap changer, conveniently mounted on the box cover, facilitating voltage adjustments after power disconnection.

Safety Protection Device Our 30-2000kVA transformers come standard with a pressure relief valve, with optional gas relays featuring alarm and trip terminals available upon user request.

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