Product Description

Introducing the 35kV series oil-immersed distribution transformers from China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. These transformers epitomize excellence with their defining traits of low energy loss, whisper-quiet operation, minimal temperature escalation, and unwavering reliability. Engineered with precision, they feature a core-hanging free design and are guaranteed to be leak-proof. Leveraging state-of-the-art design software, our transformers undergo meticulous electromagnetic calculations. Through comprehensive analysis of primary and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, and both thermal and dynamic short-circuit stability, we meticulously ensure a robust design margin. This thorough approach guarantees the reliable and safe operation of our transformers, making them a cornerstone of dependable electrical power solutions.

 

Product Characteristics

1. Our transformers incorporate a cutting-edge seven-stage temperature control technology, ensuring optimal performance.
2. Crafted with a mixed insulation system and premium-grade components, the transformer body is engineered for a 30-year lifespan, achieving exceptional durability and longevity.
3. Experience significantly reduced noise levels-our transformers operate 3 to 5 decibels quieter than the national standards, providing a serene environment.
4. Achieve peace of mind with our no-leakage guarantee: all seals are precision-engineered with acrylic one-time molded parts, and subjected to rigorous testing, including fluorescent, positive pressure, and negative pressure leak tests.
5. Built for high reliability, each transformer is equipped with an oil level thermometer, and a contact-equipped pressure relief valve placed at the oil tank's apex. The oil level indicator features a contact-equipped gauge, and the high and low-pressure bushings utilize anti-contamination reinforced pure porcelain oil bushings, catering to environments with heavy pollution levels.
6. Inside the coil, the structure is fortified with a premium insulating skeleton. Every coil is armed with internal and external braces; all braces and pads are chamfered for uniform electric field distribution and enhanced reliability. To ensure steadfastness during long-distance transport, all fasteners on the coil axis feature self-locking lock nuts, thereby preventing loosening and negating core-hanging issues.
