These transformers are designed to meet the rigorous demands of various enterprises, ensuring optimal performance and reliability.



This energy-saving, energy-efficient secondary-class oil-immersed transformer is a testament to our company's dedication to innovation. By leveraging new materials, cutting-edge technologies, and a blend of independent innovation with technology introduction, we have optimized and revolutionized the core and coil structures. This development significantly minimizes no-load loss and noise, showcasing the fruits of our self-de
veloped products.




Oil-immersed transformers provide numerous benefits, including exceptional heat dissipation capabilities that ensure stable operation. These transformers are renowned for their excellent insulation and high reliability. They offer easy voltage adjustments, catering to diverse electrical requirements, while their matured technology and cost-effectiveness make them an ideal choice for various applications.










Iron Core: The core, constructed from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, represents a new generation of iron cores. The full oblique jointed iron core features a multi-stepped section design, ensuring uniformity across the iron yoke and the core itself, enhancing efficiency and performance.

Winding: Our windings utilize corrugated oil passages and a no immersion paint process, secured with a tightening belt for stability. The concentric coil design includes high-voltage windings with taps for precise voltage adjustments, accessible via a tap changer mounted on the box cover. This allows for seamless changes to the tap voltage post power supply interruption.

Safety Protection Device: Our transformers, ranging from 30-2000kVA, are equipped with safety features like a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed as per user requirements, enhancing safety and operational integrity.
 

Apply	Mines, oil fields, subways, power plants, schools, hospitals, commercial centers, high-rise buildings
Installation height	The altitude does exceed 1000m
The waveform of the power supply voltage	similar to a sine wave

Oil Temperature Measuring Device: Each transformer comes fitted with a glass thermometer in a tube holder, strategically positioned atop the oil tank, extending 120±10 mm into the oil. For transformers in the 1000-2000kVA range, an outdoor signal thermometer is included, providing accurate and reliable temperature monitoring.

We are a professional manufacturer with 32 years of rich expertise in electric equipment manufacturing, specializing in transformers (including dry-type and oil-immersed models), voltage stabilizers, regulators, switchgear, compact substations, frequency converters, and more. Our stringent quality control system ensures unparalleled safety and quality, earning us an esteemed reputation both domestically and internationally. Customer satisfaction remains our ultimate goal, and we are committed to delivering sincere, meticulous, and satisfactory services. We warmly invite you to visit our facility and forge a lasting partnership with us.

Company Profile






The oil-immersed transformer is a new type of high-performance transformer with a more reasonable structure and better performance. Its three-dimensional wound iron core has a three-dimensional arrangement of equilateral triangles, with no air gaps in the magnetic circuit, resulting in a more compact winding and consistent and shortest lengths of the three magnetic circuits. The cross-sectional area of the iron core column is closer to a circle, resulting in further improved performance, lower losses, lower noise, and three-phase balance, reducing the third harmonic component. This product is more suitable for urban and rural areas, industrial and mining enterprises, power grid reconstruction, and is more suitable for combined transformers and pre-assembled substation transformers.


Foshan Zongcheng Electrical Co., Ltd. was established in 2018 and is located in Foshan City, Guangdong Province. It is a company mainly engaged in the manufacturing of electrical machinery and equipment. The company's registered capital is 10.08 million RMB, which exceeds that of over 95% of its peers in Guangdong Province.
