11kv Polymeric Drop Out Fuse Cutout - China

Product Detail The drop out fuse 11kv (also known as fused cutout switch) is an essential protective device in outdoor high-voltage distribution systems.

It delivers: • Short-circuit and overload protection for transformers and branch lines

• Load current switching, enabling safe maintenance and isolation

• Visible disconnection, as the fuse switches to an open position when blown, signaling a clear fault Application of Expulsion Fuse Cutout Generally, fuse cut-out contains following parts:

(1) Insulator;

(2) Metal parts;

(3) Fuse tube;

(4) Fuse element (link).

Connected with incoming feeder of distribution transformer or distribution lines, high-voltage drop-out fuse cut-out mainly protect transformer or lines form short circuit and overhead, and on/off loading current.

Cut out fuse is composed of insulators and fuse tube/carrier.

Static contacts are fixed on two sides of insulator support while moving contacts are installed on two ends of fuse tube/carrier.

Fuse tube/carrier is composed of inner arc-extinguishing tube, outer phenolic compound paper tube or epoxy glass tube.

Typical applications:

Pole-mounted distribution transformers in 11 kV networks

Overhead distribution feeders (branch lines)

Rural or utility grid systems where reliable isolation is required Why Choose Our 11 kV DropOut Fuse Reliable Electrical Protection

Supports 100 A and 200 A fuse links for different load requirements

High breaking capacity (kA) ensures effective short-circuit interruption

Designed to meet IEC 602822 (or region-specific standards like IS 9385)

High impulse withstand voltage (e.g., up to ~110 kV) for lightning protection Durable Construction & Insulation

Available with polymeric insulator (silicone / fiberglass composite) for lightweight, UV and pollution resistance

Also offered with porcelain insulator for traditional robustness

All conductive parts use high-quality copper/brass; contact surfaces are silver-plated for reliable conductivity Long Mechanical Life & Safety

Mechanical life typically ≥ 10, 000 operations in many designs

Visible drop-out of the fuse tube offers safe and instant indication of fault — supports maintenance and fault diagnostics

Large ring-pull design simplifies installation and removal for field technicians Installation & Maintenance Guidelines Ensure the fuse tube is properly seated in the jaws and the motion indicator (if any) is correctly mounted.

Maintain recommended installation angle (per spec sheet) for reliable drop action.

Use the correct rated fuse link (100A or 200A) based on coordination studies with downstream devices.

Periodically inspect and replace fuse links and tubes — particularly in polluted or corrosive environments.
