Safety in Electrical Engineering

In electrical engineering applications, filters and fabricated parts made from metal wire cloth make a decisive contribution to safety and operation of technical systems and equipment in many ways.

Application examples

  • Spark filter in electrical switch cabinets
  • Flame arrestors
  • Protective filters in smoke detectors
  • Spark protection in gas detection devices
  • Speaker covers in mobile phones and microphones
  • Contactors in energy storage media (batteries / fuel cells)

Functions at their best

  • Pressure compensation in the event of explosions in electrical control cabinets
  • Prevention of flame and spark discharge
  • Protection against foreign particles
  • Nickel wire cloth as electrodes
