Unplanned power outages caused by short-circuit faults cost utility companies, industrial facilities and commercial complexes millions in downtime, equipment replacement and lost productivity every year. Outdoor electrical distribution systems face additional challenges from harsh weather conditions, UV radiation and corrosive environments that can compromise the reliability of protection equipment.
The HAIVOL HV-2 24kV Standard Fuse Cutout is the industry-proven solution for reliable short-circuit protection in 10-38kV distribution systems. As the most widely used protection switch for distribution line branch lines and distribution transformers, it combines economic efficiency, simple operation and exceptional outdoor adaptability. This versatile device provides primary side protection for transformers and capacitor banks, and can also serve as a sectionalizing device for line maintenance and switching operations. When used with a portable loadbreak tool, it functions effectively as an overhead line disconnect switch.
All HAIVOL fuse cutouts are manufactured and tested in strict accordance with the latest international standards: IEC 60282-2:2008, IEEE Std C37.41-2008 and IEEE Std C37.42-2009, ensuring consistent performance and safety across global installations.
Our fuse cutouts are engineered to perform reliably in the most demanding environmental conditions, from high-altitude regions to coastal areas with high salt content.
Dual insulator options: Choose between polymer and porcelain insulators to match your specific application requirements
Premium porcelain construction: Porcelain bodies are bonded to hardware fittings using Por-Rok anchoring cement manufactured by CGM INC from the USA, offering rapid solidification, high mechanical strength, low expansion coefficient and superior weather resistance
Advanced polymer technology: Polymer insulators feature hardware fittings crimped onto fiberglass rods, with housings and sheds made from high-temperature vulcanized silicone rubber. The one-piece injection molding process ensures excellent sealing performance and superior tracking and erosion resistance
Heavy-duty corrosion protection: All ferrous components undergo hot-dip galvanizing with a zinc coating thickness exceeding 86μm, providing long-lasting protection against rust and corrosion
Customer benefit: Extended service life with minimal maintenance requirements, reducing total cost of ownership over the product lifecycle.
The HV-2 incorporates an innovative single-vent design that significantly improves safety and interruption capability compared to traditional multi-vent models.
Controlled exhaust direction: Gases are expelled downward and outward during interruption
Rainwater intrusion prevention: Eliminates the risk of water entering the fuse tube during operation
Upper line protection: Prevents damage to upstream equipment from free gas discharge
Improved interrupting capacity: Enhances the device's ability to safely clear short-circuit faults
Customer benefit: Increased system safety and reliability, with fewer secondary damages during fault events.
Poor electrical connections lead to excessive heat generation, energy loss and premature equipment failure. Our fuse cutouts are designed to maintain optimal conductivity throughout their service life.
High-quality copper components: All copper castings are made from bronze or brass, providing excellent mechanical strength and electrical conductivity
Silver-plated contacts: All contact surfaces are silver-plated and feature a convex design to minimize contact resistance
High-strength memory copper alloy: Ensures consistent, low-resistance contact even after repeated fuse drop-out operations
Arc-shortening copper rod: Further enhances interrupting capacity during short-circuit faults
Customer benefit: Reduced energy losses, lower operating temperatures and improved overall system efficiency.
For applications requiring load switching capabilities, our loadbreak-type fuse cutouts deliver dependable performance.
Reinforced nylon arc chamber: Constructed from special reinforced nylon material with excellent mechanical strength, anti-aging properties and flame retardancy
Wide environmental compatibility: Suitable for use in high-UV, high-altitude and coastal areas
Compatible with standard tools: Works with industry-standard portable loadbreak tools
Customer benefit: Eliminates the need for separate disconnect switches, simplifying system design and reducing installation costs.
