Product Description

The 35kV series oil-immersed distribution transformers from China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. (CEEG) are designed to deliver exceptional performance with characteristics like low loss, minimal noise, reduced temperature rise, and unparalleled reliability. These transformers are engineered to be core-hanging free and entirely leak-proof, ensuring seamless functionality. Leveraging advanced design software for electromagnetic calculations, CEEG meticulously analyzes critical factors such as the transformer's main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, and both short-circuit thermal and dynamic stability. This comprehensive approach guarantees a robust design margin, facilitating safe and reliable operation.

Product Characteristics

1. Cutting-edge core with seven-stage temperature control technology for optimal performance and durability.
2. Constructed with a mixed insulation system and premium components, this transformer boasts a life design that ensures a 30-year lifespan.
3. Whisper-quiet operation with noise levels reduced by 3 to 5 decibels below the national standard.
4. Leak-proof design utilizing acrylic one-time molded parts, supplemented by comprehensive fluorescent, positive pressure, and negative pressure leak tests.
5. Maximum reliability: Equipped with an oil level thermometer and a top-mounted pressure relief valve with a contact, an oil level gauge with a contact for the oil storage tank, and anti-fouling reinforced pure porcelain oil bushings, making it ideal for environments with heavy pollution.
6. Advanced internal coil support: The coil is reinforced with a high-quality insulating skeleton and internal and external braces. Chamfered braces and pads ensure uniform electric field distribution and enhanced reliability. The self-locking lock nuts on all fasteners along the coil axis are designed to withstand long-distance transportation without loosening or requiring core hanging.
