Product Description

The meticulously crafted 35kV series oil-immersed distribution transformers by China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. exemplify excellence with their remarkable characteristics: minimized energy loss, exceptional noise reduction, and outstanding thermal stability. These transformers promise unparalleled reliability, featuring a core-hanging free design and a commitment to leak-free performance. Utilizing cutting-edge design software, precise electromagnetic calculations are executed, including comprehensive analyses of the transformer's integral insulation properties, impulse voltage gradient distribution, and electric field dynamics. The short-circuit thermal and dynamic stability are rigorously tested to ensure ample design margins, guaranteeing the transformer's safe, efficient, and reliable operation.

 

Product Characteristic

1. Employing a state-of-the-art core seven-stage temperature control technology, the transformer ensures optimal performance.
2. Incorporating a sophisticated mixed insulation system paired with superior quality components, the transformer is crafted to deliver seamless operation with a robust lifespan of 30 years.
3. Experience tranquility with low-noise operations, achieving a noise reduction of 3 to 5 decibels below national standards.
4. Innovatively engineered to be leak-proof, with acrylic one-time molded seals and subjected to rigorous fluorescent, positive, and negative pressure leak tests.
5. Designed for high reliability, this transformer includes an oil level thermometer and a pressure relief valve with a contact on top of the oil tank. The oil level indicator utilizes a contact-equipped gauge, and both high and low-pressure bushings feature anti-fouling reinforced pure porcelain oil bushings suitable for environments with heavy pollution levels.
6. Boasting a high-quality insulating skeleton support within the coil, every detail is meticulously engineered. The coil incorporates both internal and external braces with chamfered edges to ensure uniform electric field distribution and augmented reliability. Fasteners on the coil axis are equipped with self-locking lock nuts, enabling the transformer to endure long-distance transportation without loosening or core hanging.
