HAIVOL
HAIVOL 11–15kV expulsion fuse links are high-performance overcurrent and short-circuit protection components designed for outdoor expulsion cutouts, distribution transformers, and overhead power lines. Manufactured under strict quality control and tested in accordance with IEC 60282-2 and IEEE C37.41/C37.42 standards, these fuse links deliver consistent interrupting performance, accurate time-current characteristics, and reliable long-term operation. Built for industrial power systems, utility projects, and electrical infrastructure applications, they effectively protect equipment from overloads and fault currents while minimizing downtime and maintenance costs for professional buyers and project contractors.

Type K Fuse Link Selection For Using Of Distribution Transformer Protection
The corresponding fuse is selected according to the time-current characteristics of the transformer,
usually according to the rated current of the transformer.
NOTE: Rated capacity of transformer ≤160kVA,the rated current of the selected fuse links should be 2-3 times of the full load current of the transfor-mer, Rated capacity of transformer ≥160kVA,the rated current of the selected fuse links should be 1.5-2 times of the full load current of the transformer.
Precision-engineered fuse elements ensure consistent tripping performance, avoiding false operation under normal load and guaranteeing reliable cutoff during short circuits. This reduces unplanned power outages and extends service life for transformers and connected equipment.
High density arc tubes support rapid arc extinction with no re ignition, even under low overload currents. This improves system safety and stability for outdoor distribution networks and industrial power facilities.
Reinforced connections and high strength strain wires maintain structural integrity under outdoor weather, mechanical vibration, and impulse current impact. This reduces replacement frequency and lowers long term operational costs.
Available with single or twin pigtail designs to suit different cutout structures. Twin pigtail models allow faster and more secure installation, improving on-site efficiency for large scale grid projects and maintenance teams.
