Product Description

Experience the pinnacle of transformer technology with CEEG's 35kV series oil-immersed distribution transformers. These marvels of engineering are celebrated for their exceptional low loss, whisper-quiet performance, minimal temperature rise, and unparalleled reliability. Say goodbye to core-hanging hassles and oil leaks. Leveraging cutting-edge design software, we meticulously execute electromagnetic calculations, delving deep into the intricacies of the transformer's main and longitudinal insulation. Our comprehensive analysis extends to impulse voltage gradient distribution, end electric field distribution, and both short-circuit thermal and dynamic stability strength, ensuring a robust design margin for safe and reliable transformer operation.

 

Product Characteristic

1. Embrace innovation with the transformative core seven-stage temperature control technology;
2. Designed for longevity, the transformer boasts a mixed insulation system and premium components, aligning with a 30-year life expectancy.
3. Whisper-quiet operation: Enjoy a noise reduction of 3 to 5 decibels below the national standard, setting a new benchmark for tranquility;
4. Leak-proof assurance: Utilizing acrylic, one-time molded seals, complemented by rigorous fluorescent, positive, and negative pressure leak tests, guarantees no leakage.
5. Supreme reliability: Equipped with state-of-the-art features like an oil level thermometer and a contact-fitted pressure relief valve atop the oil tank. The oil storage tank's indicator utilizes a contact oil level gauge. For environments with heavy pollution, the transformer features anti-fouling reinforced pure porcelain oil bushings, ensuring steadfast performance.
6. Impeccable construction with a high-quality insulating skeleton support inside the coil. Every coil is fortified with internal and external braces; chamfered braces and pads ensure an even electric field, enhancing reliability. Fasteners on the coil's axis utilize self-locking lock nuts, enabling the product to withstand the rigors of long-distance transportation without loosening and free of core-hanging concerns.
