Product Description

Introducing the 35kV series oil-immersed distribution transformers from China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. These sophisticated transformers boast exceptional features such as low energy loss, minimized noise levels, reduced temperature rise, and unparalleled reliability. Free from core-hanging and oil leakage, our transformers leverage cutting-edge design software for precise electromagnetic calculations. By performing comprehensive analyses on key aspects like the main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, and both short-circuit thermal and dynamic stability, we ensure generous design margins, guaranteeing the safe and uninterrupted operation of each transformer.

 

Product Characteristic: An Overview

1. Embrace the future of temperature regulation with our transformer's innovative seven-stage core temperature control technology.
2. The transformer's body integrates a hybrid insulation system alongside premium components, achieving a robust 30-year lifespan design.
3. Experience tranquility with an acoustically optimized design, reducing operational noise by an impressive 3 to 5 decibels below national standards.
4. No leakage: Our seals are crafted from high-quality acrylic one-time molded parts. Rigorous testing, including fluorescent, positive, and negative pressure leak tests, ensures impeccable sealing.
5. High reliability: Equipped with an oil level thermometer and a contact-equipped pressure relief valve atop the oil tank, our transformers feature a sophisticated oil level gauge within the oil storage tank. Built to withstand harsh environments, our anti-fouling, reinforced pure porcelain oil bushings excel in heavy pollution conditions.
6. Inside the coil, a high-quality insulating skeleton provides robust support. All coils are reinforced with internal and external braces, each thoughtfully chamfered to ensure uniform electric field distribution and enhanced reliability. The coil axis is secured with self-locking lock nuts, allowing the product to endure long-distance transport without loosening or core-hanging.
