Application Procedures-ACSR Full Tension Splices Manufacturer

ACSR Full Tension Splices are designed as a three component assembly generally for Sub-EHV applications. Consult HAIHONG for details on ACSR Full Tension Splices for EHV applications.

 

Step #1 Splice as received in the field. Place the center mark of the Steel Core Splice at the end of one conductor section, and measure back that length plus one-quarter inch. Aupply one layer of vinyl tape at this point and cut away the aluminum strands, exposing the steel core. Do the same with the other conductor section.

Step #2 Select the Steel Core Splice subset containing the greatest number of rods. Begin the application by placing the center mark of the subset at the end of one steel core and wrap on one-half its length. 

Step #3 Position the end of the other steel core so that both ends are approximately one-sixteenth inch apart. Hold it securely with finger pressure and wrap on the subset completely. 

Step #4 Match the second subset at the center mark and wrap on one or two pitch lengths on each side of the center. Apply the third subset in the same manner, then completely wrap on both subsets simultaneously. 

Step #5 Completed Steel Core Splice.

 

Step #6 Align the center mark of the Filler Rod subset (if required) containing the greatest number of rods, with the center mark of the Steel Core Splice and wrap it on.

Step #7 Match the second subset at the center mark and wrap on one pitch length from each side of the center. Start the third subset in the same manner, then completely wrap on both subsets simultaneously.

Step #8 Completed Filler Rod Splice. Do not remove the vinyl tape. To assure a reliable electrical connection, all conductors, new or weathered, must be thoroughly scratch brushed until bright and clean immediately prior to installation. A quality inhibitor must be applied to retard oxidation. 

 

Step #9 Align the center mark of the Outer Splice subset containing the greatest number of rods, with the center mark of the Filler Rod Splice and wrap it on carefully.

Step #10 Match the center mark of the first subset and apply the second subset one or two pitch lengths on each side of the center mark. Apply the third subset in the same manner, then completely wrap on both subsets simultaneously. 

Step #11 Completed Full-Tension Splice. The ends of the outer splice rods can be snapped in easily by flexing the conductor and rotating the subset with thumb pressure until the rod ends snap into position.
