Product Description

The 35kV series oil-immersed distribution transformers from China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. (CEEG) stand out with their exceptional qualities: low loss, minimal noise, reduced temperature rise, and high reliability. This core-hanging-free and leak-proof product employs cutting-edge design software for electromagnetic calculations, meticulously analyzing main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, as well as short-circuit thermal and dynamic stability. Every detail is engineered with precision to ensure ample design margins, guaranteeing the safe and reliable operation of the transformer.

Product Characteristics

1. The transformer incorporates advanced core seven-stage temperature control technology.
2. Built with a mixed insulation system and premium components, the transformer is designed to deliver consistent performance for up to 30 years.
3. Remarkably low noise levels: The noise output is reduced by an impressive 3 to 5 decibels below the national standard.
4. Leak-proof system: All seals are crafted from one-time molded acrylic parts, with rigorous fluorescent, positive pressure, and negative pressure leak tests conducted.
5. Exceptional reliability: Equipped with an oil level thermometer, a pressure relief valve with a contact on top of the oil tank, and an oil level indicator with a contact. High and low-pressure bushings utilize anti-fouling reinforced pure porcelain oil bushings, making it suitable for heavily polluted environments.
6. Enhanced durability and stability: The coil's interior features a high-quality insulating skeleton for support. All coils include internal and external braces, with chamfered braces and pads to ensure a uniform electric field and heightened reliability. Self-locking lock nuts on coil axis fasteners prevent loosening during long-distance transportation, ensuring no core hanging.
