Product Description

Introducing the cutting-edge 35kV series oil-immersed distribution transformers by CEEG, meticulously engineered to deliver unparalleled performance. Experience the epitome of efficiency with their exceptional features such as low loss, whisper-quiet operation, minimal temperature rise, and steadfast reliability. These transformers are designed to be core-hanging free, ensuring zero oil leakage. Leveraging sophisticated design software, they undergo rigorous electromagnetic calculations and in-depth analyses of key attributes like main and longitudinal insulation, impulse voltage gradient distribution, and end electric field distribution. Short-circuit thermal and dynamic stability strengths are also assessed to provide a robust design margin, ensuring these transformers operate safely and reliably, setting a new standard in power transmission solutions.

 

Product Characteristic

1. The transformer employs innovative core seven-stage temperature control technology, expertly managing heat to ensure optimal performance.
2. Built for longevity, the transformer body boasts a composite insulation system combined with premium components, aligning with a 30-year life design standard.
3. Remarkably quiet operation: Experience noise levels 3 to 5 decibels lower than national standards, ensuring a tranquil environment.
4. Impeccable sealing: Utilizing acrylic one-time molded parts for all seals, and subjected to rigorous fluorescent, positive, and negative pressure leak tests, ensuring no leakage.
5. Unmatched reliability: Equipped with an oil level thermometer and a pressure relief valve with contact on the oil tank's top, alongside an oil level gauge with contact for the oil storage tank. The high and low-pressure bushings feature antifouling reinforced pure porcelain oil bushings, ideal for heavily polluted environments.
6. Robust coil support: The internal coil structure is fortified with a high-quality insulating skeleton, with internal and external braces, all chamfered for uniform electric field and enhanced reliability. Fasteners incorporate self-locking lock nuts, ensuring stability during long transports without loosening or core-hanging issues.
