main Characteristics
Time-Current Performance
Classified as a "slow-speed" fuse with a nominal speed ratio of 6–8. It features a flatter, slower time-current curve (TCC) compared to T-type fuses, providing discrimination and coordination with downstream relays, reclosers, and other protective devices.
Construction
Typically consists of a high-purity silver or silver-copper alloy fusible element enclosed in a high-strength, heat-resistant fiber arc-extinguishing tube, with tinned copper stranded flexible leads at both ends.
Each fuse is individually packed in a small box, then the small boxes are placed into a big outer carton.


STANDARD
Manufactured and tested in accordance with IEC 60282-2 and IEEE C37.41/C37.42 international standards.
Ratings: Covers rated currents from 1A to 200A and voltages from 11kV to 38kV, suitable for standard drop-out fuse cutouts.
ADVANTAGES
System coordination: Minimizes unnecessary outages.
High breaking capacity: Reliably clears fault currents.
Outdoor durability: Corrosion-resistant and can be used in harsh weather.
Easy installation & replacement for low maintenance.
