PLC LINE TRAPS

AREAS OF USAGE

Line traps are used in transmission and distribution networks and they are the key components in PLC (Power Line Carrier) systems used remote control signals, voice communication, remote metering and control between substations in the electrical T&D networks. Line traps are used for preventing high frequency signals from going towards undesired directions.

 

MEDIUOM VOLTAGE NSPB

  • Standard : IEC 60353
  • Manufactured as per desired short circuit capacit
  • Light weight provides ease of mounting
  • Cooling spacers provides lower winding temperature
  • Ease of changing tuning box without dismantling the coil when tuning frequency changes are necessary
  • Availability of installation on capacitive voltage transformers, support insulators or suspension mounting
  • Low stray capacitance and high quality factor (Q)
  • Low, high and double bandwidth
  • Overvoltage protection againist short circuit conditions
