Product Description

Discover the pinnacle of power transmission with the 35kV series oil-immersed distribution transformers from China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. Crafted with precision and excellence, these transformers are engineered to deliver exceptional performance with their signature low loss, low noise, and low temperature rise. With unmatched reliability, core-hanging-free design, and guaranteed no oil leakage, our transformers set a new standard in the industry. Utilizing sophisticated design software, we meticulously conduct electromagnetic calculations and comprehensive analyses of the transformer's main and longitudinal insulation. We assess impulse voltage gradient distribution, end electric field distribution, and the short-circuit thermal and dynamic stability strength to ensure a robust design margin, guaranteeing safe and reliable operation at all times.

 

Product Characteristic

1. Revolutionary seven-stage temperature control technology is implemented in the core of the transformer, ensuring optimal thermal management and peak performance.
2. Built to last, the transformer body features a mixed insulation system coupled with premium components, offering an impressive 30-year life design that speaks volumes of its durability.
3. Whisper-quiet operation is a hallmark of our transformers, boasting a noise reduction of 3 to 5 decibels below the national standard, providing a tranquil energy solution.
4. Impeccable sealing: Utilizing acrylic one-time molded parts, our transformers pass rigorous fluorescent, positive pressure, and negative pressure leak tests, ensuring a leak-proof performance.
5. High reliability is woven into the fabric of our transformers. Equipped with an oil level thermometer and a contact-equipped pressure relief valve atop the oil tank, operational security is assured. The oil level indicator features a contact-compatible gauge, and the high and low-pressure bushings use anti-fouling reinforced pure porcelain oil bushings, making them ideal for even the most heavily polluted environments.
6. Inside every coil lies a high-quality insulating skeleton support, essential for maintaining structural integrity. All coils are reinforced with internal and external braces, chamfered for uniform electric fields and enhanced reliability. Our self-locking lock nuts on the coil body's fasteners ensure resilience against long-distance transportation, preventing loosening and maintaining a core-hanging-free status.
