Product Description

At the forefront of innovation, the 35kV series oil-immersed distribution transformers crafted by China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. exemplify excellence with their low energy loss, minimal noise production, optimal temperature control, and impeccable reliability. Free from core-hanging and oil leakage, these transformers are engineered with cutting-edge design software for precise electromagnetic calculations. By meticulously analyzing key aspects such as main and longitudinal insulation, impulse voltage gradient distribution, and electric field distribution, these transformers are designed with a robust margin to ensure unwavering safety and reliability throughout their operational lifespan.

 

Product Characteristic

1. The transformer is expertly designed with a sophisticated core seven-stage temperature control technology, ensuring optimal thermal management throughout its use.
2. With a commitment to longevity, the transformer body integrates a mixed insulation system coupled with premium-grade components, guaranteeing a design life span of 30 years.
3. Whisper-quiet operation: Enjoy a reduction in noise levels by 3 to 5 decibels below the national standard, setting a new benchmark for silent performance.
4. Absolute integrity: The seals are crafted from one-time molded acrylic parts, and undergo rigorous fluorescent, positive, and negative pressure leak testing to ensure zero leakage.
5. Unmatched reliability: Equipped with advanced features such as an oil level thermometer and a contact-fitted pressure relief valve atop the oil tank, this transformer boasts a high-performance oil level gauge with a contact, and resilient anti-fouling reinforced pure porcelain oil bushings, making it ideal for high pollution environments.
6. Innovative internal support: The coil is fortified with a high-quality insulating skeleton, featuring both internal and external braces that are chamfered for uniform electric field distribution, enhancing the overall reliability. Self-locking lock nuts on the coil axis ensure secure long-distance transport without loosening or core hanging issues.
