Product Description

The 35kV series oil-immersed distribution transformers, meticulously crafted by China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd., exemplify excellence with their attributes of low loss, minimal noise, reduced temperature rise, and unparalleled reliability. These transformers are engineered to be core-hanging free and boast a design that entirely eliminates oil leakage. Employing state-of-the-art design software, we perform comprehensive electromagnetic calculations, and detailed analyses of the main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, as well as short-circuit thermal and dynamic stability. This rigorous design process ensures a substantial design margin, facilitating the unwavering and safe operation of our transformers.

Product Characteristics

1. Our transformer features cutting-edge core seven-stage temperature control technology;
2. Engineered with a mixed insulation system and premium-quality components, our transformers are designed to endure a lifespan of 30 years.
3. Whisper-quiet performance: Our transformers operate 3 to 5 decibels below the national noise standards;
4. Leak-proof design: Utilizing acrylic one-time molded seals, coupled with fluorescent, positive pressure, and negative pressure leak tests, ensures zero leakage;
5. Unmatched reliability: Equipped with an oil level thermometer and a pressure relief valve on the oil tank's top, our transformers also feature an oil level indicator with a contact on the oil storage tank. The high and low-pressure bushings are made of anti-fouling, reinforced pure porcelain oil bushings, ideal for environments with heavy pollution.
6. Superior internal support: The coils are reinforced with high-quality insulating skeletons and uniform electric fields achieved through internal and external braces. All braces and pads are chamfered for enhanced reliability. Fasteners on the coil axis employ self-locking lock nuts, ensuring stability during long-distance transportation without loosening or core-hanging.
