The 35kV series oil-immersed distribution transformers crafted by China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. are engineered to perfection, featuring an impressive combination of low loss, minimal noise, negligible temperature rise, and unmatched reliability. With a core-hanging-free design and zero oil leakage, these transformers employ cutting-edge design software to precisely perform electromagnetic calculations. Thorough analyses of key elements, including main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, and both short-circuit thermal and dynamic stability, assure an ample design margin for safe, dependable operation.
Product Characteristic
- This transformer integrates state-of-the-art core seven-stage temperature control technology, ensuring optimal performance and efficiency.
- Incorporating a sophisticated mixed insulation system complemented by premium-grade components, the transformer is meticulously engineered to deliver an impressive operational lifespan of 30 years.
- Low noise: Enjoy peace and quiet with noise levels reduced by 3 to 5 decibels beyond national standards.
- No leakage: Utilizing acrylic one-time molded seals, the product undergoes comprehensive fluorescent, positive, and negative pressure leak testing to ensure no leakage.
- High reliability: Equipped with advanced features like an oil level thermometer and a pressure relief valve with contact, the transformer showcases exceptional reliability. The oil tank's oil level indicator features a contact-equipped gauge, while anti-fouling reinforced pure porcelain oil bushings on both high and low-pressure sides make it suitable for environments with severe pollution levels.
- High-quality insulating skeleton support inside the coil: The coil's interior is fortified with a superior-quality insulating skeleton. Utilization of internal and external braces, all meticulously chamfered, ensures uniform electric fields and bolstered reliability. Self-locking lock nuts secure all fasteners along the coil axis, safeguarding against loosening during long-distance transport and eliminating the need for core hanging.
