High Voltage Drop-Out Fuse Cut Out 15KV/24KV/33KV - China Suppliers and Factory for Power Distribution Protection
What are the advantages of drop-out fuses?
Reliable Overcurrent Protection
Instantly interrupts fault currents and overloads, preventing damage to expensive equipment like transformers and capacitors, and enhancing overall grid stability.
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.
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.
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)
Q1
What is a drop-out fuse cutout and how does it work?
A drop-out fuse cutout is a combination of a fuse and a disconnect switch used in overhead distribution systems. When a fault or overload occurs, the fuse link melts, causing the fuse tube to drop open under gravity and pivot downward, creating a visible air gap that isolates the faulted section from the rest of the network.
Q2
What 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 network requirements: 11KV, 15kV, 24KV, 27kV, 33kV, and 36KV, with rated currents of 100A and 200A.
Q3
What is the difference between porcelain and polymer drop-out fuse cutouts?
Porcelain cutouts offer excellent electrical insulation and long-term stability in a wide range of environments. Polymer (composite) cutouts are lighter in weight, more resistant to vandalism and mechanical impact, and perform well in heavily polluted or coastal environments due to their hydrophobic surface properties. Both types are available in our product range.
Q4
What international standards do your drop-out fuse cutouts comply with?
Our drop-out fuse cutouts are manufactured in accordance with internationally recognized standards including IEC (International Electrotechnical Commission) and ANSI (American National Standards Institute), as well as other relevant national standards, ensuring quality, safety, and interoperability across global markets.
Q5
How is the fuse link replaced after a fault operation?
After a fault operation, the fuse tube drops to a clearly visible open position. A qualified lineman can safely replace the fuse link from the ground using a standard hot stick (live-line tool), without the need to de-energize the entire line, minimizing downtime and improving operational efficiency.
Q6
Can drop-out fuse cutouts be used for transformer protection?
Yes, drop-out fuse cutouts are widely used as primary protection for distribution transformers, capacitor banks, and branch lines. They provide reliable overcurrent and short-circuit protection, and their visible open position makes them easy to identify during fault restoration, making them a cost-effective solution for transformer feeder protection.
