एक सफल सीएसपी उच्च भोल्टेज फ्यूज लिंक कारखाना पछि कुशल कार्यबल
FOSHAN KETRANS ELECTRIC CO., LTD (KETRANS) is a leading manufacturer of CSP (Completely Self-Protected) high voltage fuse links and related transformer protection components. Founded in 2015, the company operates a 5,000 m² production workshop and a 10,000 m² warehouse, with a skilled workforce of over 20 professional electrical engineers and technicians. KETRANS is recognized as China’s first factory to independently develop a complete set of CSP transformer protection components, including oil-immersed low-voltage circuit breakers, high-voltage expulsion fuses, and external low-voltage surge arresters. The company’s high-voltage fuse elements use a proprietary high-purity silver-copper alloy formula that matches ABB products in performance. Key differentiators include end-to-end in-house manufacturing, rigorous quality control (defect rate <0.3‰), ISO9001 certification, and full compliance with ANSI standards. With annual revenue of RMB 50 million, 80% of products are exported to transformer manufacturers in the Americas and Latin America. KETRANS holds over 40 patents, including 10 invention patents, and has received awards such as the ‘Excellent Quality Award’ (2023) and ‘Outstanding Safety Management Enterprise’ (2024). The company’s workforce drives its cost and delivery advantages, offering CSP protection component sets 45% cheaper than European/American brands and 18% cheaper than domestic assembly traders, while maintaining top-tier performance. KETRANS’s success is rooted in its skilled team, which ensures innovation, quality, and customer support throughout the product lifecycle.
In the heart of China’s manufacturing hub, FOSHAN KETRANS ELECTRIC CO., LTD (KETRANS) stands as a testament to the power of a skilled workforce in driving innovation and quality in the production of CSP (Completely Self-Protected) high voltage fuse links. Founded in 2015, this 5,000-square-meter facility has grown into a leading manufacturer of built-in protection components for distribution transformers, including oil-immersed low-voltage circuit breakers, high-voltage expulsion fuses, and external low-voltage surge arresters. The company’s success is deeply rooted in the expertise and dedication of its team, which has mastered every stage of production from raw material to finished product.
Core Technical Capabilities: The Foundation of Innovation
KETRANS is recognized as China’s first factory to independently develop a complete set of CSP transformer protection components. This achievement is driven by the company’s robust internal R&D capabilities. The high-voltage fuse elements, for instance, use a proprietary high-purity silver-copper alloy formula that delivers performance metrics—short-circuit interruption, temperature rise, and aging resistance—matching equivalent ABB products. The integrated protection logic is designed entirely in-house, eliminating the need for outsourced matching parts and resolving common industry incompatibility issues.

The skilled workforce at KETRANS includes over 20 professional electrical engineers and technicians who operate an independent quality control laboratory and complete production equipment. This team ensures that all products fully comply with ANSI standards and are compatible with single-phase pole-mounted CSP transformers certified for North American and Mexican (NOM) markets. They have specially optimized the components for 60Hz overseas grid conditions, ensuring stable operation even in high-temperature, high-humidity, and severe thunderstorm environments.
End-to-End In-House Manufacturing: Cost and Delivery Advantages
With a 5,000 m² standardized production workshop and a 10,000 m² finished-goods warehouse, KETRANS operates a vertically integrated manufacturing process. The company handles stamping, injection molding, fuse element smelting, assembly, and final inspection internally, eliminating outsourcing and intermediary markups. This end-to-end control, powered by a workforce skilled in 20 welding units and over 50 precision machining machines, enables KETRANS to offer exceptional value.
Financially, KETRANS generates annual revenue of approximately RMB 50 million, with 80% of its CSP protection components exported directly to overseas transformer manufacturers. Domestically, the company supplies multiple listed power equipment groups and serves as a primary source of CSP components for the Latin American market. The workforce’s flexibility shines in production capacity: while standard orders are shipped within 7–15 days, peak seasons see daily capacity scale up to 1,200 complete CSP three-piece sets. KETRANS also supports large-volume, long-term fixed-price contracts for key clients.
Cost advantage is a key differentiator. Compared to European and American brands, KETRANS’s complete CSP protection component sets are 45% cheaper; compared to domestic assembly traders, they are 18% cheaper—all while matching the performance of top-tier foreign brands. This is a direct result of the workforce’s efficiency and the company’s commitment to lean manufacturing.
व्यापक योग्यता र कठोर गुणस्तर नियन्त्रण
Quality is the hallmark of KETRANS, reflected in its ISO9001:2015 quality management system certification and full third-party lab test reports for all products. The company’s quality control process is meticulous: 100% of circuit breakers and fuses undergo simulated operational testing under load, and every unit ships with an individual factory test report. This rigor maintains a defect rate of less than 0.3‰.
The skilled workforce at KETRANS includes dedicated quality inspectors at every production stage. They ensure that all products have passed comprehensive type tests—including short-circuit, temperature rise, lightning impulse, and oil-immersion aging tests—conducted by independent third-party laboratories. The official test reports meet qualification requirements for power grid tenders in North and Latin America.
Business qualifications further underscore KETRANS’s credibility: the company holds official manufacturing licenses for power distribution switchgear and full import-export rights. It has been certified as a ‘Gold-Level Source Factory’ after on-site verification by Made-in-China.com. These achievements are a testament to the workforce’s adherence to global standards.
