They provide reliable overload and short-circuit protection: when the fuse element melts due to overcurrent, the fuse tube automatically drops under gravity, creating a visible isolation gap and clear fault indication. The tube can be easily opened with an insulating operating rod for fuse replacement without dismantling the device.<\/p>\n<p><strong>Key Features<\/strong><\/p>\n<ul>\n<li><strong>Automatic Drop-Out with Visible Break<\/strong> \u2014 Upon fuse operation the fuse carrier drops to a clearly visible open position, giving line crews immediate fault location and a safe isolation point.<\/li>\n<li><strong>Effective Arc Extinguishing<\/strong> \u2014 The arc-quenching tube generates deionizing gas under fault current to rapidly extinguish the arc; the upward exhaust design prevents inter-phase flashover.<\/li>\n<li><strong>Optional Load-Break Type<\/strong> \u2014 Models fitted with an auxiliary arc-control hood can switch rated load currents, doubling as a simple load break switch for line and transformer switching.<\/li>\n<li><strong>Weather-Resistant Insulation<\/strong> \u2014 Available with high-strength porcelain or silicone rubber composite insulation; the composite housing is shatterproof, hydrophobic and pollution-resistant.<\/li>\n<li><strong>Easy Maintenance<\/strong> \u2014 Fuse links can be replaced quickly from the ground using a hook stick; no special tools required, minimizing outage duration.<\/li>\n<li><strong>Corrosion-Proof Hardware<\/strong> \u2014 Hot-dip galvanized steel frame and stainless steel springs and pins ensure long outdoor service life.<\/li>\n<\/ul>\n<p><strong>Specifications<\/strong><\/p>\n<ul>\n<li>Rated voltage: 12kV<\/li>\n<li>Rated current: 100A \/ 200A<\/li>\n<li>Rated breaking capacity: up to 12.5kA<\/li>\n<li>Insulation: Porcelain or silicone rubber composite<\/li>\n<li>Types: Standard drop-out \/ load-break type<\/li>\n<li>Operation: Insulating hook stick<\/li>\n<\/ul>\n<p><strong>Applications<\/strong> Primary-side protection of pole-mounted distribution transformers; 10kV overhead line branch protection; rural and urban distribution networks; industrial and mining power supply; temporary construction power.<\/p>\n<p>Custom fuse link ratings, mounting brackets and load-break options are available.
