The 12kV High quality Fuse Cutout is a cost effective expulsion type protective device for 10–15kV overhead distribution lines and transformers. It integrates overload and short circuit protection, with a single vent exhaust structure that discharges gas downward and outward, preventing rain intrusion and upper line damage. Adopting high weatherability materials and silver plated contacts, it ensures stable conductivity and long term outdoor durability, widely used for transformer primary protection and line sectionalization.

Superior Weather Resistance: Polymer insulators use one piece injected silicone rubber; porcelain types use imported high strength anchoring cement, resisting aging, tracking, and erosion.
Efficient Arc Interruption: Single vent design and arc shortening copper rods boost interrupting capacity and speed up fault removal.
Low Contact Resistance: Copper castings use bronze/brass; contact surfaces are silver plated and convex designed, ensuring stable conductivity.
Strong Corrosion Protection: Ferrous parts are hot dip galvanized (zinc layer >86μm), adapting to coastal and high humidity environments.
Load Break Compatibility: Load break versions use reinforced nylon arc chambers, supporting safe load switching with portable tools.
Widely used in overhead distribution lines, rural power grids, industrial and mining power systems, photovoltaic/wind farm step up stations, and urban distribution transformer protection. It serves as short circuit protection for transformers, capacitor banks, and branch lines, and acts as a line sectionalizing device.
We provide customized solutions for enterprise clients: optional porcelain/polymer insulators, adjustable creepage distances, arc shortening rods, and various mounting brackets. Bulk orders include full quality inspection, standardized packaging, and on site technical support.
HAIVOL’s 12kV Fuse Cutout is designed and tested per IEC 60282 2:2008 and IEEE Std C37.41/C37.42 standards. With mature production technology and strict quality systems, our products feature high reliability, long service life, and cost effectiveness. We provide full lifecycle support from selection to after sales, safeguarding stable grid operation.
It provides overload and short circuit protection for distribution transformers and overhead lines, and can realize line sectionalization with load break tools.
We offer porcelain insulators (high mechanical strength) and polymer insulators (lightweight, anti pollution, easy installation).
Yes. Hot dip galvanized parts and weather resistant insulation materials provide excellent salt spray resistance.
