FDGW-35/200A 40.5KV Windproof Drop-Out Fuse

In outdoor power distribution lines, fuses are critical protective devices that prevent overcurrents and short-circuit faults. However, in areas with strong winds and harsh environments, traditional drop-out fuses are prone to nuisance tripping due to wind, severely impacting the reliability of grid operation. Leveraging its 12 years of professional experience in high-voltage switchgear, Weisho Electric proudly introduces the innovative FDGW-35 Windproof Drop-Out Fuse. This product is specifically designed for outdoor distribution lines with a rated voltage of 35kV and below, becoming an ideal choice to ensure the safe and stable operation of the power grid with its unique windproof structure, excellent arc-extinguishing performance, and superior weather resistance.

The FDGW-35 Windproof Drop-Out Fuse not only inherits the advantages of simple operation, easy maintenance, and convenient fuse replacement characteristics of drop-out fuses but also features an innovative structural optimization that significantly enhances its operational stability in strong wind conditions. Whether in mountainous, coastal, or windy regions, Weisho Electric's FDGW-35 provides reliable overcurrent and short-circuit protection, minimizing unplanned outages and improving power supply quality.

Core Advantages & Features: Breaking Tradition, Fearless in All Weather

Weisho Electric's FDGW-35 Windproof Drop-Out Fuse, through its innovative design and rigorous manufacturing, brings multiple core advantages to your high-voltage distribution lines:

• 1. Unique Windproof Structure, Eliminating Nuisance Tripping:

• Technical Detail: Features a specially designed locking mechanism or damping device that effectively resists swaying and vibration caused by wind when the fuse is in the closed position, preventing accidental dropping of the fuse during non-fault conditions. Simultaneously, the aerodynamic design of the fuse tube and contact parts has been optimized to reduce wind resistance.

• Key Benefit: Completely solves the problem of nuisance tripping in traditional drop-out fuses during strong winds, significantly improving the reliability of line operation and continuity of power supply, reducing unnecessary power outage losses and operation & maintenance costs.

• 2. Excellent Breaking Capacity & Efficient Arc Extinction:

• Technical Detail: Utilizes high-quality fuse links, coupled with high-performance arc-extinguishing materials and an optimized arc chamber structure, ensuring that in the event of a short-circuit fault, the fuse can quickly and reliably interrupt the fault current and extinguish the arc in a very short time.

• Key Benefit: Effectively limits the damage caused by short-circuit faults to grid equipment, ensuring rapid restoration of subsequent equipment operation. High breaking capacity guarantees safe isolation during grid faults.

• 3. Superior Weather & Corrosion Resistance:

• Technical Detail: Metal components undergo hot-dip galvanization or are made of stainless steel, offering excellent anti-corrosion capabilities. Insulators use high-strength ceramic or silicone rubber composite materials, with surfaces specially treated for hydrophobicity, providing UV resistance and anti-aging properties, effectively resisting erosion from salt spray, acid rain, sand, and other harsh environmental factors.

• Key Benefit: Ensures the fuse remains undeformed, rust-free, and unaged during long-term outdoor operation, significantly extending product lifespan and reducing replacement and maintenance frequency.

• 4. Convenient Operation, Efficient Maintenance:

• Technical Detail: Features a load-break diverging contact structure, making load-breaking operations safer and more reliable. Fuse replacement is simple and quick, supporting live-line operation (requires an insulated hot stick), greatly reducing power outage time.

• Key Benefit: Improves operation and maintenance efficiency, reduces the difficulty and risk of high-voltage line maintenance, saving significant labor and resources.

• 5. High Strength & Structural Stability:

• Advantage: The overall structural design is robust with high mechanical strength, capable of withstanding external impacts from wind loads, ice accumulation, and earthquakes. Easy to install and well-compatible with existing distribution line pole and tower structures.

• Key Benefit: Guarantees the structural integrity and operational stability of the fuse under various extreme natural conditions, enhancing the disaster resistance of distribution lines.

Applications: Critical Protection for Power Distribution Networks

Weisho Electric's FDGW-35 Windproof Drop-Out Fuse is widely applied in various outdoor distribution lines with a rated voltage of 35kV and below, particularly suitable for the following scenarios:

• Substation Outgoing Lines: As overcurrent and short-circuit protection for main transformers or distribution lines.

• High-Voltage Side of Distribution Transformers: To protect distribution transformers and prevent fault escalation.

• Branch Line Protection: For selective protection of overhead branch lines, isolating fault points.

• Rural Grids & Remote Areas: Simple structure and easy maintenance, especially suitable for areas with limited maintenance conditions.

• Windy, Salt-Fog, and Polluted Areas: Unique windproof and weather-resistant design ensures reliable operation in harsh environments.

• Urban Grid Renovation: Fast response, improving the automation level of the distribution network.
