  • First, mark your conductor at ¾ of the distance of the body (aluminum).
  • Properly clean the edges of the conductor with a piece of cloth or brush.
  • Before cutting the strand of a conductor, cover the ends with tape to keep the round contouring.
  • Insert the body of the dead end clamp and slide past it along the conductor till adequate conductor length protrudes from the end.
  • Cut the strands a little more than the equal depth of the forging barrel.
  • The trimming tool for cable comes in handy for the above step.
  • Now, put the core into the barrel.
  • Compress the barrel through SH dies set to make it adjacent to the rib, very close to the barrel.
  • Overlap the compressions by 6.44mm.
  • Make sure to die to close each compression.
  • Now, slide the body on the forging so that the tongue ends against the washer and eye shoulder.
  • At this stage, align the eye and tongue for proper orientation to mount the string (insulator).
  • Inject the filler compound through the filler hole so that it comes out from the washer.
  • Place the filler plug on a hole and strike with a hammer to peen the hole edge.
  • With the help of the AH die set, make compression at the ‘start’ point, which is the closest to the tongue.
  • Overlap compressions by ¼ inches.
  • Now, press ‘stop’.
  • Remember to die close to every compression.
  • Using AH die, press compression dead end clamp body against ACSR conductor.
  • Now compress the ‘start’ point and overlap compressions.
  • As the last step, press the ‘stop’ point with die closure.
  • The installation of a compression dead end clamp for ACSR conductors is complete.
  • The dead end compression part must be smooth and have a uniform surface.

Note: you can oil the grooves of the die and sleeve for better results during installation.
