Product Description

The 35kV series oil-immersed distribution transformers by China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. (CEEG) are engineered to perfection, boasting ultra-low loss, minimal noise, and a low temperature rise. These transformers are revered for their high reliability, core-hanging free design, and impeccable oil leakage prevention. Utilizing cutting-edge design software, we perform comprehensive electromagnetic calculations. Rigorous analysis of the transformer's main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, and both short-circuit thermal and dynamic stability ensures an optimal design margin. This guarantees the safe, efficient, and reliable operation of your transformer.

Product Characteristics

1. Our transformer features an advanced core seven-stage temperature control technology providing superior thermal management.
2. The body of the transformer integrates a mixed insulation system alongside premium quality components to offer a robust 30-year lifespan.
3. Low Noise: Experience a reduction of 3 to 5 decibels below the national standard, ensuring quieter operations.
4. No Leakage: Utilizing acrylic one-time molded parts for all seals, and subjecting each unit to stringent fluorescent, positive pressure, and negative pressure leak tests, we guarantee zero leakage.
5. High Reliability: Equipped with an oil level thermometer and a pressure relief valve with a contact on the oil tank top, our transformer ensures high reliability. The oil level indicator uses an oil level gauge with a contact, and anti-fouling reinforced pure porcelain oil bushings are used for both high and low pressure, suitable for heavily polluted environments.
6. High-Quality Insulating Skeleton Support: The coil's interior is reinforced with a premium insulating skeleton. All coils feature internal and external braces, with chamfered edges on all braces and pads to ensure uniform electric field distribution and enhanced reliability. Self-locking lock nuts on all fasteners safeguard against loosening, sustaining product integrity even during long-distance transport.
