Compression Splice for ACSS and ACSS/TW Conductors
Installation
Instructions
Mark the conductor a distance of ½ the length of the aluminum sleeve
Prior to making connection, the outer strands of the conductor should be
cleaned with a wire brush or abrasive cloth
Remark each conductor half the length of the aluminum sleeve, if the mark
was removed during wire brushing prior to any strand cutting, tape the end of
each conductor to help maintain the round contour
Slide the aluminum sleeve over one conductor until sufficient working length protrudes from end
Cut back aluminum strands of both conductors ½ the length of the steel sleeve
plus 1 ½ inch (38 1 mm) Do not nick the steel strands File any burrs, if present
Use of a cable trimming tool is recommended
Insert ends of steel core into steel sleeve making sure the ends butt
solidly against center stop
Using the proper SH die set, compress steel sleeve full length making initial compression over center of sleeve
Overlap each successive
compression by at least ¼ inch (6.4 mm) Complete die closure is required on all compressions
Slide the aluminum sleeve over the installed steel sleeve, centering between
the two marks that were made in Step 3
Inject AFCHT filler compound into filler hole until compound emerges from both ends of aluminum sleeve
Insert and drive filler plug (cavity up) into hole and peen edge of hole
over top surface of plug Leaving the
filler plug in the small plastic bag makes it easier to insert when working
with gloves
Using the proper AH die set, make the initial compression at the “start” mark on one side of center
The second compression should be made at the other “start” mark on opposite side of center Continue making compressions to the end, overlapping each by at least ¼ inch (6 4 mm)
Complete die closure is required for each compression Note: A light oil coating on the die grooves and
aluminum sleeve is recommended
Compressed portion of splice sleeve should have a
smooth uniform appearance if die flash is present, remove with a file or emery
cloth Remove any excess filler compound which may have been forced out the ends
of the splice
