HAIVOL's 12kV fuse cutout arrester combination is an integrated protection solution that combines a drop-out fuse and a surge arrester, specifically engineered for 11-15kV overhead distribution lines and distribution transformer primary side protection.
Drop-out fuses remain the most widely used short-circuit protection switches for 10-38kV distribution line branches and distribution transformers, valued for their cost-effectiveness, ease of operation, and exceptional adaptability to outdoor environments. Our all-in-one design builds on these strengths by eliminating the need for separate fuse and arrester installations.
Unlike individual components, our combined units reduce installation time by 40%, cut total procurement and labor costs by 25%, and minimize crossarm space usage by 50%. Each unit features optimal weight distribution to eliminate off-center loading on pole structures. All units come pre-fitted with genuine HAIVOL brand surge arresters, ensuring perfect compatibility and eliminating field assembly errors.
This solution is trusted by utility companies, electrical contractors, and industrial power operators across over 30 countries for reliable protection in both standard and harsh operating conditions.
Our units are built to withstand the most demanding outdoor environments:
Porcelain insulator option: Porcelain bodies are bonded to hardware fittings using Por-Rok anchoring cement manufactured by CGM INC (USA). This premium cement offers rapid curing, high mechanical strength, low expansion coefficient, and unmatched weather resistance.
Polymer insulator option: Hardware fittings are crimped onto high-strength fiberglass rods, with housings and sheds made from high-temperature vulcanized (HTV) silicone rubber. The one-piece injection molding process ensures perfect sealing and excellent resistance to tracking and erosion.
Corrosion protection: All ferrous components undergo hot-dip galvanizing with a minimum zinc coating thickness of 86μm, providing salt spray corrosion resistance for ≥20 years.
Customer value: Suitable for coastal areas, high-altitude regions up to 4000m, and high-UV zones, with a projected service life exceeding 30 years.
Our exclusive single-vent exhaust system delivers superior performance compared to traditional multi-vent designs:
Exhaust gases are directed downward and outward during fault interruption
Prevents rainwater intrusion into the fuse body
Eliminates damage to upper line conductors from hot gases
Increases rated interrupting capacity to 12kA for 12kV systems
Customer value: Improves short-circuit fault clearing reliability and reduces unplanned downtime.
Every conductive component is optimized for minimal energy loss and maximum reliability:
All copper castings are manufactured from high-grade bronze or brass, balancing mechanical strength and electrical conductivity
All contact surfaces are silver-plated and feature a convex design to reduce contact resistance
High-strength memory copper alloy springs maintain consistent contact pressure even after repeated fuse operations
Integrated arc-shortening copper rods significantly improve short-circuit interrupting performance
Customer value: Minimizes line losses and ensures uninterrupted operation under normal load conditions.
Loadbreak-type units feature advanced arc chamber technology:
Arc chambers are constructed from special reinforced nylon material
Excellent mechanical strength, anti-aging properties, and flame retardancy
Optimized arc quenching for safe load current interruption
Customer value: Allows for safe switching of rated load currents without additional tools, simplifying maintenance operations.
The pre-installed surge arrester provides comprehensive overvoltage protection:
Matched electrical characteristics for seamless coordination with the fuse
Simultaneous protection against short-circuit faults and lightning surges
Eliminates compatibility issues between different component brands
Reduces engineering and installation complexity
Customer value: Simplifies system design and reduces total project costs.
