    Installation Instructions Standard Compression Dead End for ACSR and ACSS Conductor

    1. Mark the conductor a distance of 3/4 the length of the aluminum body (Figure 1) .

    2. Prior to making connection, the outer strands of the conductor must be cleaned with a wire brush or abrasive cloth (Figure 2) .

    3. Prior to any strand cutting, tape the end of the conductor to help main- tain the round contour .

    4. Slide the aluminum dead end body over conductor until sufficient work- ing length protrudes from tongue end . (Figure 3) .

    5. Cut back aluminum strands equal to the depth of the steel forging bar- rel plus 1 inch (25 .4 mm) . Do not nick the steel strands . File burrs, if present . (Figure 4) . Use of a cable trimming tool is recommended . (Figure 4a, 4b) .

    6. Insert steel core into steel barrel to full length of bore . (Figure 5) .

    7. Using the proper SH die set, com- press steel barrel full length making initial compression adjacent to rib closest to barrel . Overlap each suc- cessive compression by at least ¼ inch (6 .4 mm) . Complete die closure is required on all compressions . (Figure 5a, 5b) .

    8. Slide the aluminum body over the steel forging until the tongue end butts sol- idly against felt washer and shoulder of steel eye . Align eye with tongue to desired orientation for attachment to insulator string . (Figure 6) .

    CAUTION: ACSR Dead Ends Cannot Be Used on ACSS HT Conductor

    Installation Instructions (cont.) Standard Compression Dead End for ACSR and ACSS Conductor

    9. Inject filler compound (AFC or AFCHT for HiTemp®) into filler hole until compound emerges at felt washer and tapered end of aluminum body . (Figure 6a) .

    10. Insert and drive filler plug (cavity up) into hole and peen edge of hole over top surface of plug . (Figure 7) . Leav- ing the filler plug in the small plastic bag makes it easier to insert when working with gloves . (Figure 7a) .

    11. Using the proper AH die set, make the initial compression on the alumi- num body beginning at the “start” mark nearest the tongue . Overlap each successive compression by at least ¼ inch (6 .4 mm) . Press only to the “stop” mark . Complete die clo- sure is required for each compression . (Figure 8) .

    Note: A light oil coating on the die grooves and aluminum sleeve is recommended .

    12. To press the dead end body over the conductor, use the same die used in step 11 . Begin compressing at the “start” mark about centrally located . Overlap each successive compression by at least ¼ inch (6 .4 mm) . Press to the end of the body, including the tapered portion . Complete die closure is required on each compression . (Figure 9) .

    During this compression sequence, the plastic bag in which the dead end assembly was received can be used as a medium between the aluminum body and dies (instead of oil as men- tioned in step 11) .

    13. Compressed portion of dead end body should have a smooth uniform appear- ance . (Figure 10) . If die flash is pres- ent, remove with a file or emery cloth .

    14. Remove any excess filler compound which may have been forced out the end of the dead end body .

    1 . Prior to making connections, the outer strand on all conductors (even new conductors) must be cleaned with a wire brush or abrasive cloth . If the conductor is weathered or blackened, carefully unlay aluminum strands for a distance equal to or greater than 3/4 the length of the aluminum dead end body and clean strands thoroughly with wire brush or abrasive cloth . Check accessory bore for foreign particles, removing if present .

    2 . Serve the conductor, prior to cutting, with tape to help maintain the round contour making it easier to slide the end through the aluminum dead end .

    3 . Straighten several feet of conductor removing set caused by reel (if necessary) .

    4 . If a comealong is being used, it should be located at least ten (10) feet from end of conductor .

    5 . Slide dead end body over conductor until sufficient working length protrudes from tongue end .

    6 . Cut back aluminum stands a distance equal to the depth of the bore of the steel forging barrel plus 1 inch . Do not nick steel strands . File burrs as necessary for ease of insertion .

    7 . Insert steel core into steel barrel to full length of bore .

    8 . Select die size for compressing steel barrel . The die size on the die and die size marked on steel barrel must be the same .

    9 . Compress steel barrel full length making initial compression adjacent to corrugations . Overlap each successive compression by approximately 1/4 die bite . Complete die closure is required for each compression .

    10 . Remove any remaining tape from the aluminum strands and slide aluminum dead end body over steel forging until tongue end butts solidly against felt washer and shoulder of steel dead end . Align clevis or eye with tongue of dead end to ensure proper positioning when dead end is fastened to insulator hardware .

    11 . Inject AFL Filler Compound (AFC) into filler hole until compound emerges at the felt washer and the tapered end of the body . Insert and drive filler plug into hole and peen edge of hole over top surface of plug .

    12 . Select die size to compress aluminum dead end body . Die size for aluminum dead end body and die size marked on die must be the same .

    13 . It is recommended that die grooves be well lubricated with a light weight oil . Oil coating should be maintained during entire compression operation .

    14 . Make the initial compression on the dead end body over the steel shank beginning at the "start knurl" nearest the dead end tongue . Continue making compressions to the "stop knurl", overlapping the previous compression by approximately 1/4 die bite . Complete die closure is required for each compression .

    15 . To press the dead end body over the conductor, use the same die used in step 13 . Make the initial compression at the "start knurl" and proceed with compression . Continue making compressions to the end of the dead end body, overlapping the previous compression by approximately 1/4 die bite . Complete die closure is required for each compression .

    16 . Note there should be an uncompressed area on the dead end body where it covers the compressed barrel of the steel forging (area of the filler plug) .

    17 . Compressed portion of the dead end should have a smooth uniform appearance . Remove flash, if present, with file or emery cloth .
