Product Description

The 35kV series of oil-immersed distribution transformers crafted by China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd., are engineered with an impressive array of features tailored to meet your needs: they boast exceptionally low energy loss, minimal noise, reduced temperature rise, and unparalleled reliability. These transformers are designed to free you from the hassle of core-hanging and oil leakage issues. Our cutting-edge design software facilitates precise electromagnetic calculations, meticulously analyzing key elements such as the transformer's primary and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, and both short-circuit thermal and dynamic stability. This innovative approach ensures ample design margin, thereby guaranteeing the transformer's safe and dependable operation at all times.

 

Product Characteristic

1. The transformer incorporates advanced core seven-stage temperature control technology, ensuring optimal performance and efficiency.
2. The transformer body is constructed using a sophisticated mixed insulation system and top-tier components, designed to extend its lifespan to an impressive 30 years.
3. Low noise: Our transformer operates at a noise level 3 to 5 decibels below the national standard, ensuring a quieter environment.
4. No leakage: With seals crafted from premium acrylic one-time molded parts, our rigorous testing includes fluorescent, positive, and negative pressure leak evaluations to ensure absolute integrity.
5. High reliability: Equipped with an advanced oil level thermometer and a contact-equipped pressure relief valve on the oil tank's top, the transformer features an oil level gauge with contact for the oil storage tank. High and low-pressure bushings utilize anti-fouling reinforced pure porcelain oil bushing, suitable for environments with heavy pollution.
6. High-quality insulating skeleton support inside the coil: The coil is reinforced with an exceptional insulating skeleton enhancing stability. All coils integrate internal and external braces with chamfered edges for uniform electric field distribution, elevating overall reliability. Fasteners on the coil's body use self-locking lock nuts, ensuring they endure long-distance travel without loosening or core-hanging issues.
