Product Description

Introducing the cutting-edge 35kV series oil-immersed distribution transformers by China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd., renowned for their outstanding features that redefine industry standards. These transformers promise unparalleled performance with key characteristics including exceptionally low loss, minimal noise, reduced temperature rise, and superior reliability. They are core-hanging free and boast a robust design that eliminates oil leakage. With the utilization of sophisticated design software, our transformers undergo precise electromagnetic calculations and rigorous analyses of main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, and both short-circuit thermal and dynamic stability strength. This meticulous attention to detail ensures a generous design margin, guaranteeing the safe and dependable operation of our transformers.

 

Product Characteristic

1. Experience the brilliance of our transformers equipped with innovative core seven-stage temperature control technology;
2. Crafted with a mixed insulation system and premium components, our transformer body is engineered for a remarkable 30-year life design, ensuring longevity and durability.
3. Low noise: Exceeding national standards, our transformers operate with noise levels reduced by an impressive 3 to 5 decibels;
4. No leakage: Utilizing precision-engineered acrylic one-time molded parts for all seals, combined with rigorous fluorescent, positive, and negative pressure leak tests, we guarantee a leak-free performance;
5. High reliability: Featuring an oil level thermometer, a contact-equipped pressure relief valve atop the oil tank, and an oil level gauge with contact for the oil storage tank. Additionally, the high and low-pressure bushings are crafted from anti-fouling reinforced pure porcelain oil bushing, perfectly suited for heavy pollution environments.
6. High-quality insulating skeleton support inside the coil: Engineered for excellence, the coil's interior is fortified with a high-quality insulating skeleton. Each coil is reinforced with internal and external braces, meticulously chamfered for uniform electric field distribution and heightened reliability. The coil axis features self-locking lock nuts on all fasteners, ensuring resilience against the rigors of long-distance transportation without core loosening.
