High Voltage Fuses
Siba Product Picture

German DIN Standard For Air & Gas Insulated Switchgears Outdoor Switchgears

HV Fuse-links have parallel connected pure silver fuse-elements. The design and method of production of the elements ensures narrow tolerances of time-current characteristics. The fuse elements are wound on a ceramic support and are attached to the silver plated connection caps by means of spot-welding.

 

The connection caps are fitted inside the silver plated copper end caps by spot welding. The copper end caps themselves are press-fitted onto the porcelain tube, which is glazed inside and outside. The end caps are furthermore mechanically fixed to the porcelain tube and additionally sealed by a durable elastic sealing medium. This sealing method has been proven over many decades of positive field experience and ensures tightness against ingress of humidity.

IEC 60282-1
BS 2692
ESI 12-8


 

Side view

  Design and construction of these fuses follow the well-proven concept of all high-voltage fuse-links. For pressure resistant encapsulation, high-grade ceramic is used. Contact material consists of silver plated high conductivity copper. The pure silver melting elements are provided with appropriate notches to ensure small time/current-curve tolerances and low let-through currents. The arc quenching quartz sand is subject to special survey criteria regarding its composition, grain size and humidity content.
