High Voltage Fuse Cut Out 15KV/24KV/33KV - Reliable China Suppliers and Factory for Power Distribution Protection
What are the advantages of drop-out fuses?
โก
Reliable Overcurrent Protection
Instantly interrupts fault currents and overloads, preventing damage to expensive equipment like transformers and capacitors, and enhancing overall grid stability.
๐๏ธ
Clear Visible Break
Upon fusing, the fuse link melts, releasing the fuse tube which drops down and pivots, providing a clear, visible open gap. This allows linemen to quickly identify and locate the faulted section, speeding up restoration.
๐ก๏ธ
Robust & Durable Construction
Manufactured from high-strength materials such as polymer-housed or porcelain-housed designs, our fuse cutouts are built to withstand harsh environmental conditions, including UV radiation, moisture, and temperature extremes.
๐
Safe Operation & Isolation
The drop-out action provides a visible air break, ensuring safe isolation of the faulted circuit for maintenance crews. They are designed for easy and safe fuse link replacement from the ground using a hot stick.

Frequently Asked Questions (FAQ)
โWhat is a drop-out fuse cutout and how does it work?
A drop-out fuse cutout is an outdoor electrical protection device used on medium-voltage distribution lines. When a fault or overload occurs, the fuse link inside the fuse tube melts. This releases the tube, which pivots downward under gravity, creating a visible open-circuit gap that clearly indicates the fuse has operated.
โWhat voltage ratings are available for your drop-out fuse cutouts?
Our drop-out fuse cutouts are available in a range of rated voltages to suit different distribution systems: 11KV, 15kV, 24KV, 27kV, 33kV, and 36KV, with rated currents of 100A and 200A.
โWhat is the difference between porcelain and polymer housing types?
Porcelain-housed cutouts offer excellent electrical insulation and are highly resistant to surface tracking and environmental aging. Polymer-housed cutouts are lighter in weight, more resistant to vandalism, and provide superior performance in heavily polluted or coastal environments due to their hydrophobic surface properties.
โWhat international standards do your drop-out fuse cutouts comply with?
Our products are manufactured in accordance with recognized international standards including IEC (International Electrotechnical Commission) and ANSI (American National Standards Institute), as well as other relevant national standards, ensuring consistent quality and interoperability.
โHow do I safely replace the fuse link after it has operated?
Drop-out fuse cutouts are specifically designed for safe field maintenance. After the fuse operates and the tube drops to the open position, a qualified lineman can safely remove and replace the fuse link from the ground using a standard hot stick (live-line tool), without the need to de-energize adjacent lines.
โWhat equipment can drop-out fuse cutouts protect?
Drop-out fuse cutouts are commonly used to protect distribution transformers, capacitor banks, feeder branches, and other medium-voltage electrical assets. They serve as the first line of overcurrent defense, isolating faulted sections quickly to minimize damage and reduce overall system downtime.
