Product Description

Crafted with precision and expertise, the 35kV series oil-immersed distribution transformers by CEEG embody excellence with their exceptional features. Revel in the advantages of low loss, low noise, and minimal temperature rise. Each transformer is meticulously engineered to deliver high reliability, ensuring no oil leakage and featuring a core-hanging free design. Our transformers promise safe and dependable operation, thanks to sophisticated design software that conducts comprehensive electromagnetic calculations. This includes detailed analysis of main and longitudinal insulation, impulse voltage gradient distribution, and end electric field distribution, alongside assessments of short-circuit thermal stability and dynamic strength. These rigorous evaluations guarantee ample design margin, fortifying the transformer's steadfast performance.

 

Product Characteristics

1. Pioneering transformer technology: Our state-of-the-art core employs an innovative seven-stage temperature control system, ensuring optimal performance.
2. Crafted for longevity: The transformer's body incorporates a mixed insulation system combined with premium quality components, achieving a remarkable 30-year design life span.
3. Quiet operation: Experience tranquility with a noise level reduced by 3 to 5 decibels, outperforming national standards.
4. Impeccable sealing: Utilizing one-time molded acrylic seals and rigorous tests, including fluorescent, positive, and negative pressure leak assessments, we ensure zero leakage.
5. Unmatched reliability: Equipped with a sophisticated oil level thermometer and a pressure relief valve with contact on the oil tank top. The oil level indicator features a contact oil level gauge. Anti-fouling reinforced pure porcelain oil bushings are used for high and low pressure, ideal for heavily polluted environments.
6. Robust coil design: The coil's interior is supported by a top-notch insulating skeleton, featuring internal and external braces. Chamfered braces and pads ensure uniform electric fields, enhancing reliability. Every fastener on the coil axis is secured with self-locking lock nuts, allowing the transformer to endure long-distance transportation without loosening or core-hanging.
