Product Description

Experience the exceptional performance of CEEG's 35kV series oil-immersed distribution transformers. Engineered for excellence, these transformers boast attributes like minimal energy loss, whisper-quiet operation, reduced thermal rise, and unparalleled reliability. Notably, they are core-hanging free, ensuring no oil leakage for a maintenance-free experience. Utilizing cutting-edge design software, every transformer undergoes meticulous electromagnetic calculation and rigorous analysis. This includes assessing the main and longitudinal insulation, impulse voltage gradient distribution, end electric field dynamics, as well as ensuring short-circuit thermal and dynamic stability. These processes guarantee a robust design margin, ensuring the transformers operate safely and reliably, meeting the most demanding power transmission needs.

 

Product Characteristic

1. Featuring state-of-the-art core seven-stage temperature control technology, this transformer represents innovation at its finest.
2. With a commitment to longevity, the transformer integrates a sophisticated mixed insulation system and premium components, achieving a remarkable 30-year life design.
3. Remarkably low noise levels: our transformers operate 3 to 5 decibels quieter than national standards.
4. Eliminating leakage: Comprehensive sealing with acrylic one-time molded parts, combined with rigorous fluorescent, positive pressure, and negative pressure leak tests ensure absolute tightness.
5. Unrivaled reliability: Equipped with an oil level thermometer and a top-mounted pressure relief valve with contact, this transformer is built for high-stakes environments. The oil storage tank features an oil level gauge with contact, and the bushing boasts anti-fouling reinforced pure porcelain for optimal performance in severe pollution conditions.
6. Robust coil design: Supported by a superior insulating skeleton, each coil is fortified with internal and external braces. Precision chamfered braces and pads ensure uniform electric fields and heightened reliability. Self-locking lock nuts on the coil axis fasteners guarantee steadfast integrity during long-distance transportation, preventing loosening and eliminating core hanging concerns.
