HAIVOL
HAIVOL brand fuse links offer reliable overcurrent protection for medium-voltage electrical systems. Available in types K, T, H, and SLOW-FAST, these fuse links are engineered for precise operation, durability, and compliance with international standards.
Manufactured and tested according to the latest international standards: IEC 60282-2:2008, IEEE Std C37.41-2008 & IEEE Std C37.42-2009
Available in various types: K, T, H, and SLOW-FAST fuse links
Excellent mechanical strength, resistant to vibration and high current impact
Superior arc extinguishing performance for low current overload faults
Twin pigtails option available for easier installation in fuse cutouts
Accurate time-current characteristics
Amps | Diameter of buttonhead mm | Size of arc extinguishing tube mm |

| 46Amp | ∅19.00 | ∅10.0*130 |
11-15kv Fuse link length 21'(533mm)
24-27kv Fuse link length 23'(584mm)
33-38kv Fuse link length 31'(787mm)
The corresponding fuse is selected according to the time-current characteristics of the transformer,
usually according to the rated current of the transformer.
Fusible element: Made of silver-copper alloy for optimal conductivity and melting characteristics
Arc extinguishing tube: Constructed with materials exhibiting excellent arc quenching properties
Strain wire: High-strength material used to secure the fusible element, ensuring durability
Precision technology employed in manufacturing process
Strict testing procedures to guarantee accurate time-current characteristics
Compliance with international standards ensures consistent quality
Rigorous mechanical strength tests to verify resistance to vibration and high current impact
Suitable for use in distribution transformer protection
Applicable in both single-phase and three-phase electrical systems
Ideal for outdoor installations in various environmental conditions
Recommended for use in electrical networks with voltage ratings from 11kV to 38kV
For transformers ≤160kVA: Select fuse links with rated current 2-3 times the full load current of the transformer
For transformers >160kVA: Select fuse links with rated current 1.5-2 times the full load current of the transformer
