Fuse Link Type Solutions for 1500V DC

Since 1992, ZHNYU ELECTRIC has focused on low-voltage electrical components, and fuse link type products remain a core line. Because we manufacture load isolating switches, fuse-type isolating switches, isolating switch fuse groups, fuses, and knife switches in-house, every fuse link type is matched to its carrier before shipment, removing the fit and coordination risks common with mixed sourcing. Our 10,000+ square meters of office and plant space houses 100+ production equipment units, including automated welding, silver-plating, and 100% routine test benches.

International buyers need more than a working fuse link type; they need evidence. ZHNYU holds ISO9001, CCC, and CE certifications, a metering production license, and strict RoHS compliance. Each fuse link type shipment can include material declarations, temperature rise and breaking capacity test reports, and batch traceability records. This documentation supports utility tenders, railway safety reviews, and industrial control audits in 60+ export countries. Our engineering team also helps with fuse link type selection across 690 V AC and 1,500 V DC systems, including derating for 45-60 C ambient conditions in metallurgy and petrochemical plants. In a Southeast Asia railway project, our fuse link type elements were tested for 2,000 operations and 20,000 hours of accelerated vibration, cutting failures 63% in 12 months.
