Based in Jinhua, Zhejiang, we combine robust manufacturing capabilities with a deep understanding of global power infrastructure needs, serving markets from North America and Europe to Southeast Asia and Africa.
The RW11-12KV fuse link is designed as a cost-effective and reliable solution for overload and short-circuit protection in 12KV outdoor power systems. Its core value lies in preventing equipment damage and minimizing outage times, thereby ensuring grid stability and operational safety.
Detailed Features & Technical Advantages:
- Robust Porcelain Housing: The high-strength porcelain body provides excellent mechanical strength, superior weather resistance against UV rays, rain, and temperature fluctuations, and high dielectric strength for reliable insulation.
- Precise Protection Characteristics: The internally housed fuse element is meticulously calibrated to provide accurate time-current characteristics, ensuring selective coordination with upstream and downstream protection devices.
- Clear Indication: Features a visible operation indicator (optional), allowing for quick visual confirmation of a blown fuse, which aids in rapid fault location and maintenance.
- Drop-Out Design: Upon operation, the fuse link body drops down, providing a clear, visible isolation point that enhances safety for maintenance personnel.
- Easy Installation & Replacement: Designed for compatibility with standard outdoor fuse cutouts, enabling straightforward installation and replacement without specialized tools.

Frequently Asked Questions (FAQ):
Q1: What is the primary application of the RW11-12KV fuse link?
A: It is specifically designed for overload and short-circuit protection in 12KV outdoor power distribution lines, commonly used on poles to protect transformers, feeders, and other distribution equipment.
Q2: Why is a porcelain housing used instead of polymer?
A: Porcelain offers superior resistance to tracking, UV degradation, and extreme temperatures compared to many polymers. It provides excellent long-term dielectric stability and mechanical strength in outdoor environments, making it a reliable choice for harsh conditions.
Q3: Are different current ratings available?
A: Yes. We offer a standard range of current ratings from 6.3A up to 100A. Please consult with us to select the correct rating for your specific load and protection coordination requirements.
Q4: How does the "drop-out" feature work and why is it important?
A: When the fuse element melts due to an overcurrent, the housing is designed to detach and pivot downward, hanging visibly from the cutout. This provides a clear, visible indication of the operated fuse and creates a physical air gap for safety during maintenance.
Q5: What standards does this product comply with?
A: The fuse link is manufactured to meet the general performance and testing requirements of relevant international standards such as IEC and ANSI for high-voltage fuses. Specific standard compliance details can be provided upon request based on your market.
Q6: What is the typical delivery lead time?
A: Lead times vary based on order quantity and specific ratings. For standard items, we generally maintain stock for prompt shipment. We ship from major Chinese ports for efficient logistics.
Q7: Can you provide custom markings or packaging?
A: Customized markings, labeling, and packaging options are often available to meet specific client or project requirements. Please inquire with our sales team for possibilities.
Q8: How should these fuse links be stored before installation?
A: They should be stored in a dry, clean environment, away from direct exposure to corrosive chemicals or extreme moisture. The original packaging is designed to protect the porcelain during transit and storage.
