Product Description

The prestigious 35kV series oil-immersed distribution transformers crafted by CEEG are renowned for their exceptional features including minimal loss, hushed operation, reduced temperature elevation, and unparalleled dependability. These transformers are ingeniously designed to eliminate core-hanging and prevent oil leakage. Our product leverages state-of-the-art design software to meticulously perform electromagnetic calculations. A comprehensive analysis encompassing the transformer's main and longitudinal insulation, impulse voltage gradient distribution, terminal electric field distribution, as well as thermal and dynamic stability under short-circuits, is executed via computer simulation. This ensures a generous design margin, guaranteeing the transformer's steadfast and reliable performance.

 

Product Characteristic

1. Ingeniously engineered, this transformer is equipped with cutting-edge core seven-stage temperature control technology,
2. The transformer structure boasts a sophisticated mixed insulation system, integrated with premium components to match a remarkable life expectancy of 30 stellar years.
3. Delivering serenity in operation, its noise level is reduced by an impressive 3 to 5 decibels below the national standard,
4. Engineered for perfection, this transformer guarantees no leakage. Seals are crafted from high-grade acrylic molded parts, and undergo meticulous fluorescent, positive pressure, and negative pressure leak testing,
5. Offering unmatched reliability: this transformer comes equipped with an oil level thermometer, and a pressure relief valve with a contact atop the oil tank. The oil storage tank's level indicator incorporates an oil level gauge with contact, while the robust anti-fouling reinforced pure porcelain oil bushing is designed for environments with heavy pollution,
6. Inside the coil, a high-quality insulating skeleton support is meticulously applied. All coils are fortified with internal and external braces, each chamfered for uniform electric field distribution enhancing reliability. Every fastener on the coil's axis employs self-locking lock nuts, ensuring resilience against long-distance transport vibrations without any loosening or core suspension.
