As a dedicated manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in producing reliable electrical protection components for global power infrastructure. Our High-Voltage Fuse Link for Overhead Lines is engineered to provide dependable overcurrent protection in 10KV/12KV systems, safeguarding critical equipment and ensuring the continuity of power supply. With over a decade of experience and a commitment to quality backed by a comprehensive management system, we deliver products that meet the rigorous demands of utilities and industrial clients worldwide.

Product Features & Technical Advantages:

Robust Construction: The fuse link utilizes a high-grade insulating body, typically ceramic or a durable composite material, offering excellent mechanical strength and resistance to environmental stressors like UV radiation, moisture, and temperature fluctuations common in overhead line applications.
Precision Protection: Designed as a K-Type (expulsion type) fuse, it operates by interrupting the circuit through the expulsion of arc products. This design provides a clear, reliable breaking action for fault currents within its 200A-300A rating range.
Adaptable Ratings: Available in the standard voltage classes of 10KV and 12KV, and current ratings from 200A to 300A, allowing for selection based on specific system requirements and load profiles.
Easy Installation & Maintenance: The unit is designed for straightforward mounting on overhead line structures. Its configuration often includes compatible brackets or fittings, facilitating quick replacement during maintenance schedules without extensive downtime.
Enhanced Safety: The expulsion mechanism and insulating design help contain the arc energy during operation, contributing to a safer environment for the surrounding infrastructure and personnel.

Frequently Asked Questions (FAQ):

What is the primary function of this K-Type fuse link?
This fuse link acts as an overcurrent protection device on overhead power lines. When a fault current exceeding its rating occurs, it operates to safely interrupt the circuit, protecting downstream equipment.
How do I select the correct current rating (200A, 250A, 300A, etc.)?
Selection should be based on the normal full-load current of the circuit segment you are protecting. It should be higher than the maximum load current but appropriately rated to clear fault currents effectively. Consult your system design specifications.
Is this fuse link suitable for both 10KV and 12KV systems?
Yes, the product is designed and rated for use in both 10KV and 12KV overhead line systems. Ensure you specify the required voltage rating when ordering.
What is the typical installation process for this fuse link?
Installation involves mounting the fuse unit onto the designated bracket or holder on the overhead line structure using standard tools. The process is generally straightforward and does not require specialized equipment.
How does the "K-Type" or expulsion mechanism work?
In a K-Type fuse, when the fusible element melts due to overcurrent, the resulting arc is extinguished by the expulsion of gases or arc products through a designed vent, providing a visible indication of operation and clearing the fault.
What are the key environmental considerations for this product?
The insulating body is designed to withstand outdoor conditions, including rain, heat, cold, and UV exposure. Its material selection ensures long-term performance without significant degradation.
Can I request custom current ratings outside the 200A-300A range?
While 200A-300A is our standard production range, Jinhua Dika, as a manufacturer, may have the capability for customization. Please inquire directly for specific non-standard rating requirements.
What is the expected service life or replacement interval?
The fuse link itself does not have a defined service life under normal conditions; it remains inert until a fault occurs. However, periodic visual inspection as part of line maintenance is recommended to check for physical damage or environmental wear.
