HAIVOL Fuse Cutout
HAIVOL Fuse Cutout series features the Expulsion Fuse Cutout (dropout fuse) as its core, complemented by Fuse Links (fusible cores) and Current-Limiting Fuse (current-limiting high-voltage fuses). These fuses are designed for sectionalizing, protection, and maintenance in medium-voltage power distribution. The complete solution combines selectivity, environmental adaptability, and lifecycle low maintenance, helping utilities and industrial users steadily reduce faults, improve efficiency, and lower total cost of ownership.
Feature Box
Weatherproof
Porcelain or polymer (silicone rubber) insulation resists UV, pollution, and coastal salt fog, maintaining creepage and surface performance in harsh climates. Single-direction, downward arc-gas venting helps protect adjacent hardware during storms, icing, or blowing sand.
Reliable
The drop-out design creates a visible air gap after operation, reducing mis-closing risk and speeding patrol confirmation. Silver-plated contacts, galvanized/stainless hardware, and optional loadbreak arc control keep contact resistance stable and switching consistent over long service intervals.
Cost-efficient
A simple architecture with quick-replace fuse links minimizes maintenance time and spares complexity. Standard footprints and hot-stick operation shorten installation and outage windows—delivering protection and isolation at a lower total cost than breaker-based lateral schemes.
HAIVOL Fuse Cutout Series
Expulsion Fuse Cutout - Severe-weather visible isolation.
A drop-out tube creates a clear air gap crews can verify from the ground—even in heavy rain, salt fog, snow, or icing. Single-direction downward venting and porcelain/polymer insulation keep arc gases and contaminants away from adjacent hardware, so faults are sectionalized faster and restoration is safer with fewer mis-operations.
Fuse links for expulsion fuse cutout
Certified to trip the nearest fuse—not the whole line. Type-tested to IEC 60282-2 and IEEE C37, our K/T/H and slow/fast links have calibrated response times so the link closest to the fault operates first. That means upstream gear stays closed, outages are confined to one section, and coordination and spare stocking remain simple across 11–38 kV.
Current-limiting fuse
Full-range, fast-acting transformer protection—current-limiting HRC with certified striker options. Rated 7.2–40.5 kV and 6.3–200 A, it offers full-range performance at 12 kV and 24 kV, extremely quick operation with low power dissipation/temperature rise, and pyrotechnic or spring strikers—all type-tested to GB/IEC/DIN/BS for dependable isolation of transformer primaries.
Why Choose HAIVOL
Complete MV protection
From expulsion fuse cutouts and coordinated fuse links to cabinet-grade current-limiting fuses, our portfolio covers overhead lines and switchgear end-to-end—type-tested to IEC/IEEE for predictable protection and easier sourcing.
Built for severe weather, built to last
Porcelain or polymer insulation, corrosion-resistant hardware, and downward expulsion venting deliver visible isolation and stable performance in rain, salt fog, snow, and heat—supporting faster, safer restoration.

For decades, the visible break has been the definitive hallmark of a disconnect switch—a tangible, eye‑verified air gap assuring isolation. However, modern power distribution demands are pushing this century‑old paradigm to its limits. Compact gas‑insulated switchgear (GIS), solid‑dielectric systems, and fully enclosed outdoor units no longer accommodate a conventional open‑air gap. Moreover, renewable energy installations, offshore wind farms, and desert solar plants expose switches to relentless condensation, corrosive atmospheres, and extreme thermal cycles. To meet these challenges, a new generation of disconnect switches is emerging—one that replaces the visible break with advanced mechanical designs, active anti‑condensation strategies, and materials engineered for the harshest environments. This article explores the key design trends driving this evolution.Technical Resources -
The humble disconnect switch, a fundamental component in electrical distribution and protection for over a century, is undergoing a profound transformation. As industries worldwide accelerate towards digitalization and the demands for grid resilience, predictive maintenance, and operational efficiency intensify, the "dumb" mechanical switch is rapidly evolving into an intelligent, data-rich node within the Industrial Internet of Things (IIoT). The outlook for 2025 points to an accelerated integration of advanced sensors, sophisticated motor state monitoring, and seamless remote programmability, redefining the role of this critical asset.Technical Resources -
Traditional scheduled maintenance operates on a fundamental assumption: that age or simple visual cues are reliable proxies for an insulator's health. This is particularly problematic for composite insulators, where critical failure modes—like core brittleness, interface degradation, or hidden puncture damage—are not always visible. Inspections are labor-intensive, subject to human error and variability, and expose personnel to risk. Furthermore, this model results in either over-maintenance, wasting resources and operational lifespan, or under-maintenance, increasing the risk of unplanned outages, flashovers, and wildfires.Technical Resources
