The 11-15kV drop-out fuse cutout serves as overhead line protection equipment for electrical distribution systems. Manufactured with USA CGM anchoring cement and components featuring 86μm+ hot-dip galvanized coating, this unit provides automatic fault isolation with manual reset capability. The design incorporates a porcelain insulator body, brass contact assembly, and galvanized steel mounting hardware for pole-mounted installation. Each unit undergoes mechanical and electrical testing prior to shipment. This 18-year manufacturing process supports consistent production standards for commercial procurement across global markets.
Rated voltage (KV) | Rated current (A) | Rated interrupting current (KA) | Lightning impulse withstand voltage to ground (BIL KV) | Minimum power frequency withstand dry voltage to ground (KV) | Minimum creepage distance (mm) |
11-15 | 100/200 | 12 | 110 | 42 | 220 |
11-15 | 100/200 | 12 | 125 | 50 | 320 |
This fuse cutout interrupts overload and short-circuit conditions within 11-15kV distribution networks. The expulsion-type operation extinguishes arcs during fault conditions, while the drop-out mechanism provides visible indication of circuit interruption. The unit supports 100A and 200A current ratings with 12kA interrupting capacity. System operators can identify fault locations immediately through the visible drop-out position, reducing troubleshooting time for maintenance teams.
The 86μm hot-dip galvanized coating provides corrosion resistance for outdoor deployment. Porcelain insulators offer 220mm and 320mm creepage distance options for areas with different pollution levels. The unit withstands 110kV and 125kV BIL impulse voltages and 42kV and 50kV power frequency dry voltages. The brass contact mechanism maintains consistent electrical connection across temperature variations from -40°C to +55°C, supporting operation in diverse climate conditions.
Mount the fuse cutout on utility poles using standard pole line hardware. Select the appropriate fuse link based on system voltage and protected load current rating. Secure incoming and outgoing conductors to line and load terminals using torque values specified for conductor size. Verify proper alignment of the fuse tube to ensure unobstructed drop-out operation during fault events. Perform continuity testing and mechanical operation checks before energizing the circuit. Conduct periodic inspections of contact surfaces and galvanized coating condition.

This equipment operates within 11-15kV overhead distribution networks, supporting both 11kV and 15kV system configurations commonly used in utility power distribution.
Yes, the design incorporates hot-dip galvanized metal components and porcelain insulation specifically engineered for continuous outdoor exposure in distribution networks.
The drop-out action provides visible fault indication, allowing maintenance personnel to identify affected circuit sections without additional testing equipment. Fuse tube replacement occurs without system shutdown when proper isolation procedures follow.
With proper installation and periodic maintenance, the unit operates for 15-20 years in typical distribution network environments, depending on atmospheric pollution levels and fault occurrence frequency.
Utility companies, industrial facility power systems, rural electrification projects, commercial building distribution, and renewable energy grid connections all deploy this fuse cutout for circuit protection requirements.
