This high voltage fuse cutout features industry-leading weather resistance for long-term outdoor operation. Porcelain insulators use US-made CGM INC por-rok anchoring cement for cement pouring, delivering rapid solidification, high mechanical strength, and low expansion coefficient. Polymer insulators adopt one-piece injection molding with high-temperature vulcanized silicone rubber, ensuring excellent sealing and tracking erosion resistance. All ferrous parts undergo hot-dip galvanizing with a zinc coating over 86μm for superior corrosion resistance.
Our electrical distribution standard fuse cutout adopts a single vent design, with downward and outward exhaust during interruption to prevent rainwater intrusion and improve interrupting capacity. All copper castings use high-grade bronze/brass, with silver-plated convex contact surfaces to reduce contact resistance and ensure excellent conductivity. High-strength memory copper alloy sheets guarantee stable contact, while an arc-shortening copper rod enhances short-circuit interruption performance for distribution system stability.
Loadbreak-type units feature an arc chamber made of special reinforced nylon, with high mechanical strength, anti-aging, and flame retardant properties. All products are manufactured and tested in strict accordance with IEC 60282-2:2008, IEEE Std C37.41-2008, and IEEE Std C37.42-2009 standards, ensuring consistent performance in standardized distribution projects.
