The 11kV 100A porcelain cutout fuse (with interrupter) is an overcurrent protection device for medium voltage distribution lines (6-11kV), integrating porcelain insulator and high-efficiency interrupter to achieve fast breaking (≤10ms), visible breakpoint isolation and long-life maintenance. Key benefits include:
High arc control: The arc extinguisher is designed with a breaking capacity of up to 16kA, which is suitable for frequent operation scenarios (such as industrial power distribution, photovoltaic/wind power collector lines).
Anti-fouling and flashover performance: the creepage distance of the porcelain umbrella skirt ≥ 450mm (suitable for grade IV dirt areas).
Mechanical reliability: porcelain bending strength ≥ 10kN, contact pressure ≥ 250N, mechanical life ≥ 2000 times.
Typical Applications:
Primary side protection of distribution transformers
Overhead line segment fault isolation
Incoming protection of ring main unit in industrial plant
Lightning protection cooperation in high thunderstorm areas
