1,500V DC Protection for PV & Rail

The fuse link transformer is a critical component in modern low-voltage power distribution, combining the functions of a disconnector, a fuse holder, and a transformer protection device. At ZHNYU ELECTRIC, our manufacturing process begins with precision stamping of copper contacts, followed by silver plating for low contact resistance. Each fuse link transformer is assembled on automated lines with torque-controlled fasteners and then subjected to 100% routine tests, including dielectric withstand, temperature rise, and mechanical endurance. We produce over 500,000 fuse link transformer units annually, supported by 100+ production equipment units and a 10,000+ square meter facility. Our R&D team of 35 engineers continuously improves arc extinction and thermal performance. In photovoltaic applications, our fuse link transformer handles DC voltages up to 1,500V and ambient temperatures up to 70°C. In industrial control, it provides visible isolation and short-circuit protection up to 100kA. In railway and petrochemical sectors, it resists vibration, humidity, and corrosive gases. We export to 60+ countries, with key markets in Europe, Southeast Asia, and the Middle East. A German panel builder reduced assembly time by 25% after switching to our plug-in fuse link transformer. A Brazilian OEM achieved 40% fewer field returns. Our fuse link transformer complies with IEC 60947-3 and IEC 60269, and holds ISO9001, CCC, CE, and RoHS certifications. We offer OEM branding, custom ratings, and a 24-month warranty. With 34 years of experience, ZHNYU is your trusted partner for fuse link transformer solutions.
