High Voltage Fuses

German DIN standard for air and gas insulated switchgear and outdoor switchgear.

High voltage Fuse-links have parallel connected pure silver fuse-elements. The design and methods of production of the elements ensures narrow tolerances of the 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 elastimer sealing medium. This sealing method has been proven over many decades of positive field experience and ensures tightness against ingress of humidity. Inquires for fuse high voltage custom applications are welcome.

Side view

Medium voltage fuses according British Standard are backup fuses for the protection of substations up to 24 kV. The fuse links of this section comply with the following national and international standards:

  • IEC 60282-1
  • BS 2692
  • ESI 12-8

Design and construction of these fuses follow the well-proven concept of all high-voltage fuse-links. Pressure resistant encapsulation and a 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.
