Product Description

Introducing our cutting-edge 35kV series oil-immersed distribution transformers from China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. These transformers are engineered to perfection with an array of standout features, including remarkably low losses, minimal noise production, reduced temperature increase, and exceptional reliability. With a core-hanging free design and guaranteed no oil leakage, this product ensures longevity and stability. Utilizing advanced design software, we conduct comprehensive electromagnetic calculations and meticulous analyses of key transformer attributes such as primary and longitudinal insulation, impulse voltage gradient distribution, and both short-circuit thermal and dynamic stability strengths. This ensures a generous design margin and fosters the utmost safety and reliability throughout operational life.

 

Product Characteristic

1. Our transformer incorporates an innovative core seven-stage temperature control technology,
2. Crafted with a mixed insulation system and premium components, the transformer body is designed with the unparalleled durability to last 30 years.
3. Whisper-quiet performance: Noise levels are impressively reduced by 3 to 5 decibels below national standards,
4. Leak-proof engineering: Featuring acrylic one-time molded parts for all seals and rigorous fluorescent, positive, and negative pressure leak testing;
5. Unmatched reliability: Outfitted with an oil level thermometer, a pressure relief valve with contact, and an oil level gauge with contact on the storage tank, this transformer is further fortified with anti-fouling reinforced pure porcelain oil bushings to thrive even in heavily polluted environments.
6. Superior coil support: The coils are bolstered by a high-quality insulating skeleton, ensuring stability. All braces are both internally and externally enhanced, with chamfered edges for uniform electric fields, boosting the reliability of the transformer. Fasteners on the coil axis are self-locking lock nuts, offering resilience against long-distance transport vibrations without risk of loosening or core displacement.
