In the modern electrical grid, the Potential Transformer (PT) Fuse serves as a critical guardian of measurement and protection circuits. As global energy demands shift toward smart grids and renewable integration, the requirement for high-reliability, OEM-manufactured fuses has reached an all-time high. Wenzhou Shuguang Fuse Co., Ltd., with over three decades of engineering excellence, stands at the forefront of this industrial evolution.
Global industrialization and the rapid expansion of urban power infrastructures in regions like Southeast Asia, the Middle East, and Africa have intensified the need for specialized China OEM Potential Transformer Fuses Factories. These components are not merely circuit breakers; they are precision-engineered devices designed to clear short-circuit faults within milliseconds, protecting expensive voltage transformers from catastrophic failure.
International utilities are increasingly sourcing from specialized factories in China to balance high technical standards with cost-efficiency. Our fuses are integrated into substations worldwide, ensuring stable power delivery.
Customization is the heartbeat of our factory. We provide tailored solutions for various voltage levels (12kV, 24kV, 36kV) conforming to international DIN, BS, and ANSI standards.
With the rise of IoT-enabled transformers, our fuses offer the high breaking capacity required to handle the complex transient states of modern digital grids.
Located in Yueqing, Zhejiang Province—the electrical capital of China—Wenzhou Shuguang Fuse Co., Ltd. is a power technology enterprise integrating research, development, production, sales, and service. The predecessor of our company was the "Yueqing Shuguang Fuse Factory," established in 1992.
For over 30 years, we have dedicated ourselves to the perfection of high-voltage protection technology. Our journey from a local factory to a globally recognized China OEM Potential Transformer Fuses Factory is built on a foundation of rigorous testing and customer-centric innovation.
As switchgear becomes more compact, PT fuses must deliver higher current-limiting performance in smaller envelopes. Our R&D focus is on high-density ceramic housings.
With renewable energy sites often located in harsh offshore or desert environments, our fuses are designed with anti-corrosive end-caps and UV-resistant materials.
Future trends point towards fuses equipped with micro-sensors. We are currently exploring "Smart Fuse" indicators that communicate status to central SCADA systems.

Global procurement teams from Europe to Southeast Asia require more than just a product; they require a partnership. As a leading China OEM Potential Transformer Fuses Factory, we provide:
We use 95% alumina ceramics for fuse tubes and high-purity silver for the fuse element, ensuring minimal power loss and maximum breaking capacity.
Our modernized production lines in Yueqing allow us to handle bulk orders for large-scale utility projects while maintaining short lead times.
From specific melting characteristics to unique physical dimensions, our engineering team can modify designs to fit legacy systems or new installations.
Protecting potential transformers in high-voltage switchgear (10kV - 35kV), preventing internal faults from affecting the entire busbar system.
In solar and wind farms, our fuses protect the sensitive monitoring equipment required for grid synchronization.
Heavy industries like steel mills and chemical plants rely on "Shu Rong" brand fuses for their private power distribution networks.
Our products are exported to various provincial power companies in China, forming a complete sales network. Beyond domestic success, our high-voltage fuses and current-limiting products are exported to Southeast Asia, the Middle East, Africa, and Europe.
The company adheres to the principle of "Development by science and technology, and survival by quality." We sincerely welcome customers from home and abroad to discuss cooperation and work together for the prosperity and development of the electric power industry.
