FOSHAN KETRANS ELECTRIC CO., LTD (KETRANS), established in 2015 with a 5,000 m² manufacturing facility, is a leading Chinese manufacturer of CSP (Completely Self-Protected) high-voltage fuse links and related transformer protection components. As the country’s first factory to independently develop a complete CSP protection system, KETRANS produces oil-immersed low-voltage circuit breakers, high-voltage expulsion fuses, and external surge arresters in-house, using a proprietary high-purity silver-copper alloy for fuse elements that matches ABB performance. All products comply with ANSI standards and are optimized for 60 Hz grids and harsh environments.

KETRANS’s vertical integration—handling stamping, smelting, assembly, and testing—eliminates outsourcing, enabling 45% cost savings over European/American brands and 18% over domestic traders. With annual revenue of ~RMB 50 million, 80% of output is exported, primarily to the Americas. The company maintains flexible production (up to 1,200 three-piece sets daily) and offers 7–15 day lead times. Rigorous quality control includes ISO 9001:2015 certification, third-party type tests (short-circuit, thermal, impulse, aging), 100% load testing, and a defect rate below 0.3‰. KETRANS holds over 40 patents, 10 invention patents, and multiple awards for quality and safety. Their customer-focused approach, coupled with engineering prowess, makes them a trusted partner for transformer manufacturers worldwide.

In the realm of distribution transformer protection, few names command as much respect and reliability as FOSHAN KETRANS LISTRIK CO, LTD (commonly known as KETRANS). Established in 2015, this Chinese manufacturer has rapidly ascended to become a premier supplier of Completely Self-Protected (CSP) components, particularly high-voltage fuse links. With a 5,000-square-meter manufacturing facility and a dedicated team of over 20 professional electrical engineers, KETRANS has carved a niche for itself by delivering products that match, and in many cases exceed, the performance of global benchmarks like ABB.

Kemampuan Teknis Inti

KETRANS stands 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 fuses, and external low-voltage surge arresters. Unlike competitors who often outsource matching parts, KETRANS designs all protection logic in-house, ensuring seamless compatibility and eliminating the risks of component mismatch—a common industry headache.

At the heart of their high-voltage fuse links lies a proprietary high-purity silver-copper alloy formula. This advanced metallurgy yields performance metrics—short-circuit interruption capability, temperature rise stability, and aging resistance—that rival those of ABB’s equivalent products. Because these fuses are optimized to work in tandem with KETRANS’s own CSP circuit breakers, the entire system delivers coordinated protection that reduces nuisance trips and enhances transformer lifespan.

All products comply strictly with ANSI standards and are specially engineered for 60 Hz overseas grid conditions. They are compatible with single-phase pole-mounted CSP transformers certified for North American and Mexican (NOM) markets. Additionally, KETRANS’s designs undergo rigorous testing to ensure stable operation in high-temperature, high-humidity, and severe thunderstorm environments, making them ideal for demanding climates across the Americas.

Manufaktur In-House End-to-End & Nilai Luar Biasa

Since its founding, KETRANS has invested heavily in vertical integration. The company operates a 5,000 m² standardized production workshop and an expansive 10,000 m² finished-goods warehouse. Equipped with 20 welding units and over 50 precision machining machines, every stage of production—from stamping and injection molding to fuse element smelting, assembly, and final inspection—is handled internally. This eliminates outsourcing and intermediary markups, directly benefiting customers through lower costs and tighter quality control.

KETRANS’s annual revenue stands at approximately RMB 50 million, with 80% of its CSP protection components exported to overseas transformer manufacturers. Domestically, they supply multiple listed power equipment groups, and they serve as the primary source of CSP components for the Latin American market. Such broad market acceptance underscores the trust placed in KETRANS’s engineering.

Flexibility is another hallmark. The company maintains ready stock for standard specifications, offering a 7–15 day lead time for standard orders. During peak seasons, daily capacity can scale to 1,200 complete CSP three-piece sets. For key clients, KETRANS supports large-volume, long-term fixed-price contracts, ensuring cost predictability and supply security.

Cost advantage is dramatic: 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 value proposition has made KETRANS a go-to partner for cost-conscious yet quality-driven transformer manufacturers worldwide.

Kualifikasi Komprehensif & Kontrol Kualitas yang Ketat

KETRANS operates under a fully implemented ISO 9001:2015 quality management system, with dedicated quality inspections at every production stage. Testing and validation are paramount: all products pass 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 the strict 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. It is certified as a ‘Gold-Level Source Factory’ following on-site verification by Made-in-China.com. Quality control extends to 100% of circuit breakers and fuses undergoing simulated operational testing under load. Every unit ships with an individual factory test report, and the defect rate is maintained at less than 0.3‰—a testament to KETRANS’s commitment to zero-defect manufacturing.

Portofolio Kekayaan Intelektual yang Luas

KETRANS protects its innovations through a robust intellectual property strategy. The proprietary brand KETRANS is backed by over 40 patents, including 10 invention patents. These patents cover key innovations such as oil-immersed circuit breaker designs, expulsion-type high-voltage fuse structures, and the unique CSP protection core architecture. Additionally, the company holds multiple utility model and design patents, and has 6 registered trademarks covering electrical products and foreign trade services. This IP portfolio not only safeguards KETRANS’s technology but also assures customers of original, high-performance solutions.
