Fournisseur de liaisons fusibles haute tension CSP avec une expérience mondiale à l’exportation
FOSHAN KETRANS ELECTRIC CO., LTD (KETRANS) is a leading global supplier of CSP (Completely Self-Protected) high voltage fuse links, established in 2015 with a 5,000 m² production facility and 10,000 m² warehouse. The company specializes in integrated protection components for distribution transformers, including oil-immersed circuit breakers, high-voltage expulsion fuses, and low-voltage arresters. As China’s first factory to independently develop a full CSP system, KETRANS uses a proprietary high-purity silver-copper alloy in its fuse elements, achieving performance comparable to ABB and full ANSI compliance. Vertical in-house manufacturing—covering stamping, injection molding, smelting, assembly, and testing—eliminates intermediaries, offering 45% cost savings vs. European/American brands and 18% vs. domestic traders. With 80% of output exported, KETRANS serves transformer manufacturers in North America and Latin America, maintaining a defect rate under 0.3‰ through ISO9001:2015 certification, third-party type tests, and 100% load testing. The company holds over 40 patents, including 10 invention patents, and multiple awards such as the 2023 Excellent Quality Award. Flexible production scales to 1,200 CSP sets daily, with 7–15 day lead times for standard orders. KETRANS’ combination of technical expertise, cost efficiency, rigorous quality, and global export experience makes it a trusted partner for reliable CSP transformer protection.
Dans le paysage concurrentiel de la distribution électrique, la fiabilité et l’innovation sont primordiales. FOSHAN KETRANS ELECTRIC CO., LTD (KETRANS) se distingue comme un fournisseur de premier plan de fusibles haute tension CSP (Fully Self-Protected), soutenu par une vaste expérience mondiale dans l’exportation. Fondée en 2015, l’entreprise s’est rapidement imposée comme un leader dans la fabrication de composants de protection intégrés pour transformateurs de distribution, notamment les disjoncteurs basse tension immergés en huile, les liaisons fusibles haute tension et les arrête-tension. Avec une usine de production de 5 000 mètres carrés et un entrepôt de 10 000 mètres carrés, KETRANS combine technologie de pointe avec un service centré sur le client pour offrir une valeur inégalée dans le monde entier.
Capacités techniques de base : pionnier de la technologie CSP
KETRANS is recognized as China’s first factory to independently develop a complete set of CSP transformer protection components. This integrated system includes oil-immersed low-voltage circuit breakers, high-voltage expulsion fuse links, and external low-voltage surge arresters. All components are designed with proprietary logic to ensure seamless interoperability, eliminating the compatibility issues that often plague multi-vendor solutions. The high-voltage fuse elements are crafted from a unique high-purity silver-copper alloy formulation, achieving performance metrics—such as short-circuit interruption, temperature rise, and aging resistance—that match equivalent ABB products. These fuses are optimized for KETRANS’ own CSP circuit breakers, resolving industry-wide challenges of component incompatibility.
Les produits sont entièrement conformes aux normes ANSI et sont spécifiquement conçus pour les transformateurs CSP monophasés montés sur poteaux certifiés pour les marchés nord-américain et mexicain (NOM). Ils sont optimisés pour des conditions de réseau à 60 Hz à l’étranger, assurant un fonctionnement stable dans des environnements à haute température, à forte humidité et à orages violents. Cette excellence technique positionne KETRANS comme un partenaire de confiance pour les fabricants de transformateurs recherchant des solutions de protection robustes.

Fabrication interne de bout en bout : avantages en termes de coûts et de livraison
Operating a 5,000 m² standardized production workshop and a 10,000 m² finished-goods warehouse, KETRANS handles every step of manufacturing in-house—from stamping and injection molding to fuse element smelting, assembly, and final inspection. This vertical integration eliminates outsourcing and intermediary markups, delivering exceptional value. The company’s annual revenue of approximately RMB 50 million reflects its strong market position, with 80% of CSP protection components exported directly to overseas transformer manufacturers. Domestically, KETRANS supplies multiple listed power equipment groups and serves as a primary source of CSP components for the Latin American market.

Flexible production capacity ensures rapid response: standard specifications are kept in ready stock, with a 7–15 day lead time for standard orders. During peak seasons, daily capacity can scale up to 1,200 complete CSP three-piece sets. The company also supports large-volume, long-term fixed-price contracts for key clients. Compared to European and American brands, KETRANS’ 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.
Qualifications complètes et contrôle qualité rigoureux
KETRANS implements the ISO9001:2015 quality management system with dedicated inspections at every production stage. All products undergo comprehensive type tests—including short-circuit, temperature rise, lightning impulse, and oil-immersion aging tests—conducted by independent third-party laboratories. Official test reports are issued, meeting qualification requirements for power grid tenders in North and Latin America. The company holds official manufacturing licenses for power distribution switchgear and full import-export rights, and is certified as a ‘Gold-Level Source Factory’ following on-site verification by Made-in-China.com. Quality control is stringent: 100% of circuit breakers and fuses undergo simulated operational testing under load, and every unit ships with an individual factory test report, maintaining a defect rate of less than 0.3‰.
Portefeuille étendu de propriété intellectuelle
Under the proprietary brand KETRANS, the company holds over 40 patents, including 10 invention patents. These cover oil-immersed circuit breakers, expulsion high-voltage fuses, and CSP protection core structures.
