• 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.
