Product Description

The 35kV series oil-immersed distribution transformers from China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. are the epitome of engineering excellence, boasting remarkable attributes like low energy loss, minimal noise, reduced temperature rise, and unparalleled reliability. These transformers are meticulously designed to be core-hanging free with no risk of oil leaks. Utilizing cutting-edge design software, we perform comprehensive electromagnetic calculations and analyses. From main and longitudinal insulation scrutiny to impulse voltage gradient distribution, and from end electric field analysis to short-circuit thermal and dynamic stability evaluations, every aspect is optimized by computer algorithms. This extensive process guarantees a robust design margin, ensuring that our transformers operate safely and reliably at all times.

 

Product Characteristic

1. This transformer features an innovative core seven-stage temperature control technology, promising enhanced performance and efficiency.
2. Crafted with a sophisticated mixed insulation system and top-tier components, this transformer is engineered for a 30-year life cycle, ensuring longevity and durability.
3. Experience tranquility with our low-noise technology, surpassing national standards by reducing noise levels by an impressive 3 to 5 decibels.
4. Our commitment to no leakage is unwavering. Each seal is crafted from high-grade acrylic through a one-time molding process, undergoing rigorous fluorescent, positive, and negative pressure leak testing.
5. Boasting supreme reliability, the transformer includes an oil level thermometer and a pressure relief valve equipped with contact on the oil tank's top. The oil level indicator of the storage tank features an oil level gauge with a contact, and the high and low-pressure bushings are anti-fouling, reinforced pure porcelain oil types, ideal for environments with high pollution levels.
6. Inside the coil, a high-quality insulating skeleton provides robust support. All coils are fortified with internal and external braces, with all braces and pads meticulously chamfered for uniformity in the electric field, boosting reliability. The fasteners on the coil axis feature self-locking lock nuts, ensuring stability and resilience during long-distance transportation without loosening or compromising the core.
