Application range, types
Preliminary note
SIBA HV-fuses are fuses for the protection of substations up to 40,5 kv.
The fuse-links of this section comply with the following national and international standards:
- DIN 43 625
- BS 2692-1
- ESI 12-8
Design and construction of these fuse-links follow the well-proven concept of all SIBA high-voltage fuse-links. For pressure resistant encapsulation, high grade techn. porcelain is used. Contact ma- terial consists of silver plated high conductivity copper. The pure silver melting elements have appropriate notches to ensure small time-current curve tolerances and low let-through currents. The arc quenching quartz sand is subject to particular survey criteria regarding its composition, grain size and humidity content.
