INSTALLATION INSTRUCTIONS

CONVENTIONAL COMPRESSION DEADENDS

FOR AAC CONDUCTOR

The compression dead end assembly consists of an aluminum body with or without terminal pads and a steel eye dead

end forging. Assemblies may also include jumper terminals. If included, jumper terminals include mounting hardware.

The standard aluminum dead end terminal pad is angled at 15, as is the pad on the jumper terminal. This permits either a

30 or straight jumper loop take-off. Fittings are stamped with conductor type and diameter range, die size, minimum

press size, production date code and catalog number.

1. Prior to installation the conductor must be clean, straight and in lay. Any bend in conductor section will tend to make

the deadend body tube bow during compression.

2. Remove the protective plastic wrap. Set unwrapped connector on a clean surface and ensure the bores of the

aluminum deadend body is clear of foreign matter.

3. Coat the ribbed section of the steel deadend forging with Fargo joint compound type UJC and insert the coated

section into the aluminum deadend body. With the steel eye inserted until its felt washer is against the aluminum body

and aligned as needed relative to the insulator connection hardware, compress the aluminum body onto the steel eye

ribbed section using die tooling stamped on the aluminum body. Make first crimp next to knurl mark nearest the eye

end and continue crimping to the second knurl mark, overlapping crimps slightly to prevent formation of ribs between

crimps.

4. Inject Fargo joint compound into the mouth of the deadend body. For the approximate amount required, see table

below.

5. Mark the conductor end at insertion length. Insertion length is the distance from the from the third knurl ring to open

tube end.

6. With a clean stainless steel wire brush (V-brush type recommended), aggressively brush the conductor end over the

full circumference and insertion length. Immediately apply a generous coat of FARGO UJC over the just brushed

conductor strands. Insert conductor into the aluminum body to the insertion length. Rotate the aluminum body on the

conductor as needed to ensure full insertion.

7. Select AH die set specified on deadend body. Mount die halves in press and lubricate die faces and the conductor

crimp zone length of the deadend body with clean oil or clean plastic wrap. If plastic used as lubricant, ensure that it

wraps completely around the splice tube, fully covering both die face during each compression.

8. Move press to third knurl mark and make first on span side of that mark. Continue compressions out to the ends of

the deadend body. Overlap each crimp by an amount necessary to prevent the formation of ridges between adjacent

crimps. Be sure that full die closure occurs with each crimp. To minimize bowing of deadend tube during

compression, keep both die faces and splice crimp zone well lubricated during crimp operation, and keep the deadend

tube firmly seated in one die half while dies are closing.

9. Remove excess joint compound and any marking tape used. Remove die flash from deadend body and file or sand

for a smooth appearance.

10. If deadend supplied as a kit with jumper terminal, the required terminal hardware sheet is included. Refer to separate

instruction sheet for jumper terminal installation. EHV installations without jumper loops will require bolt shields on

terminal pad connections.

DO NOT COMPRESS IN THE REVERSE DIRECTION

DO NOT APPLY LINE TENSION TO DEADEND PRIOR TO COMPLETION OF ALL COMPRESSION
