99.8% Uptime, Global Compliance

In 2023, a 200 MW photovoltaic installation in Andalusia faced frequent nuisance tripping due to inadequate fuse and base assemblies from a previous supplier. Our technical team conducted a site audit and recommended our high-breaking-capacity fuse and base units, which are engineered for DC applications with rated voltages up to 1500V. Within six weeks, we delivered 12,500 sets, each featuring a UV-stabilized base and gF/aR fuse links that withstand harsh outdoor conditions. The new assemblies reduced downtime by 40% and improved the overall system availability to 99.8%. The project manager noted that our fuse and base combinations simplified maintenance, as the modular design allowed for quick replacements without special tools. This deployment has since become a reference for other solar developers in Europe, leading to three additional orders from the region.

A chemical processing facility in Saudi Arabia experienced frequent electrical failures in its motor control centers, attributed to corrosion and vibration in the harsh desert environment. ZHNYU ELECTRIC provided a customized fuse and base solution featuring a glass-reinforced polyamide base with IP65 protection and silver-plated fuse links that resist sulfidation. The initial order for 3,000 units was installed in critical circuits feeding pumps and compressors. Over 12 months, the plant reported zero fuse-related failures, cutting unplanned maintenance by 60% and saving an estimated $250,000 in lost production. The engineering director praised the fuse and base assembly's robust clamping mechanism, which prevented loosening due to vibration, and its clear indication window that simplified visual inspections.

Indian Railways sought to modernize its signaling systems along a 1,500-km corridor, requiring fuse and base solutions that could handle fluctuating loads and frequent surges. Our engineers proposed a standardized fuse and base system with a rated breaking capacity of 120kA and optional fuse monitoring contacts. Over a phased 18-month rollout, we supplied 8,800 units that were installed in signal interlocking cabinets. The new fuse and base assemblies demonstrated a lower total cost of ownership by 30% compared to previous imported solutions, and their compact footprint saved cabinet space by 20%. The railway authority reported a 95% reduction in fuse-related signaling disruptions, significantly improving train punctuality.
