• Impedance bond is one of the most important component in Railway Signaling.
Impedance Bond provides electrical continuity for traction return current despite discontinuity caused by Insulated Joints
• Impedance Bond Transforms and Transfers Signals between Tracks and Signaling Components located in the Cabins
• Impedance Bond offers high Impedance to the signals generatedfrom the components located in
the cabinsthus protecting them against surges
• Impedance bond offers galvanic insulation between the components located in the Cabin and the track
» Impedance Bond consists of a track Coil and an Auxiliary coil wound on magnetic circuit housed in a enclosure
» Impedance Bonds are Oil filled or Resin filled
» Impedance Bonds are tuned with Capacitors connected Across Auxiliary coil to achieve required impedance
