Product Description

The state-of-the-art 35kV oil-immersed distribution transformers from China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. (CEEG) boast unparalleled low loss, minimal noise, reduced temperature rise, and stellar reliability. Designed with advanced electromagnetic software, these transformers feature core-hanging-free construction and leak-proof integrity. Through meticulous analysis covering main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, and short-circuit thermal and dynamic stability, we guarantee a robust design margin, ensuring the transformer's safe and reliable operation.

Product Characteristics

1. The transformer utilizes innovative core seven-stage temperature control technology;
2. With a mixed insulation system and premium parts, our transformer is built for a 30-year lifespan.
3. Whisper-quiet operation: Noise levels are reduced by 3 to 5 decibels below the national standard;
4. Leak-Proof Design: Featuring acrylic one-time molded seals and comprehensive leak tests including fluorescent, positive, and negative pressure evaluations;
5. Exceptional Reliability: Equipped with an oil level thermometer and a pressure relief valve at the top of the oil tank, a contact-equipped oil level gauge in the oil storage tank, and anti-fouling reinforced pure porcelain oil bushings for both high and low pressure, making it ideal for heavy pollution environments.
6. Superior Insulating Support: The coil's interior is reinforced by high-quality insulating skeletons. Comprehensive internal and external bracing with chamfered pads ensures a uniform electric field and enhanced reliability. Self-locking lock nuts on all coil body fasteners prevent loosening and core hanging during long-distance transportation.
