Product Description

The 35kV series oil-immersed distribution transformers crafted by China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. are engineered to perfection, featuring exceptional traits like minimal loss, whisper-quiet operation, reduced temperature rise, and unmatched reliability. Free from core-hanging worries and oil leaks, these transformers embody engineering excellence. Harnessing advanced design software, we conduct comprehensive electromagnetic analyses, meticulously scrutinizing main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, as well as thermal and dynamic stability under short-circuit conditions. This meticulous approach ensures ample design margins, guaranteeing the transformer's robust and dependable performance.

 

Product Characteristics

1. Seven-stage core temperature control technology enhances the transformer's performance and longevity.
2. With a sophisticated mixed insulation system and superior-quality components, our transformers are designed to provide an impressive 30-year lifespan.
3. Ultra-quiet operation: Noise levels are reduced by an additional 3 to 5 decibels below the national standard.
4. Leak-proof design: All seals are crafted using precision-molded acrylic parts, complemented by rigorous fluorescent, positive, and negative pressure leak testing.
5. Enhanced reliability: Equipped with an oil level thermometer and a pressure relief valve with contacts on the oil tank's top. The oil storage tank level indicator features a contact-equipped gauge. Anti-fouling reinforced pure porcelain oil bushings ensure dependable performance in heavily polluted environments.
6. Premium insulating skeleton support: Inside each coil, a high-quality insulating skeleton provides robust support. Coils are reinforced with both internal and external braces, with all braces and pads meticulously chamfered for uniform electric field distribution, bolstering reliability. Self-locking lock nuts secure all coil axis fasteners, ensuring the product remains intact during long-distance transportation without loosening or core hanging.
