High voltage fuse
max. 40.5 kV, DIN 43 625, BS 2692-1, ESI 12-8 | HHD SIBA

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.
