Overview

The ABB Autoset Automatic Tension Splice, SKU ATS1020, is a wide-range mechanical splice designed for reliable termination of aluminum conductors in overhead power distribution systems. Engineered by ABB Installation Products, this splice accommodates conductor sizes from 1/0 through 2/0 AWG, including ASCR (Aluminum Conductor Steel Reinforced), AAAC (All Aluminum Alloy Conductor), and AAC (All Aluminum Conductor) cables. The product features a color-coded system for quick identification: yellow indicates the 1/0 AWG range, while gray denotes the 2/0 AWG range. Key features include an automatic tensioning mechanism that eliminates manual adjustments, ensuring consistent grip and electrical continuity without specialized tools. The splice incorporates internal pilot cups and strand guides to facilitate smooth conductor insertion, reducing installation time and minimizing human error. Proper preparation requires straightening conductors, removing curvature, and cleaning with a wire brush followed by application of non-gritted oxide-inhibitor compound (e.g., Blackburn CTB). For ACSR conductors, additional cleaning with aluminum conductor cleaner is required. Installation follows a two-step process: first, insert the conductor with a continuous straight thrust until it reaches the center stop; second, apply momentary hand-set tension to engage the gripping jaws. The splice's design ensures full tension application only, making it unsuitable for slack spans. Internal components must remain protected in the supplied plastic bag until installation to prevent contamination. This splice is specifically recommended for utility and industrial applications requiring dependable aluminum conductor connections, including overhead power line construction and maintenance. Its robust construction and ABB engineering deliver long-term performance in outdoor and industrial environments where environmental resistance is critical. The ATS1020 is a direct replacement for traditional compression splices in applications where automatic tensioning and wide conductor compatibility are required.
  • Wide range compatibility: 1/0–2/0 AWG for ASCR, AAAC, and AAC aluminum conductors

How to Install the ATS Wide Range Automatic Tension Splice

This guide provides step-by-step instructions for preparing conductors and installing the ATS Wide Range Automatic Tension Splice for ACSR, AAAC, and AAC conductors, ensuring a secure and reliable connection.

Estimated time: 30m

Tools needed:

Bristle wire brush

Supplies needed:

ATS wide range splice, Tape or marking device, Good quality aluminum conductor cleaner, Non-gritted oxide-inhibitor compound

  1. Select the Proper Splice

    Select the appropriate ATS wide range automatic tension splice for the job. Verify the wire size and type, which are clearly marked on the splice, ensuring it is suitable for ACSR, AAAC, or AAC conductors.

  2. Straighten and Trim the Conductor

    Straighten the conductor to remove any curvature. If using old conductors, cut them back sufficiently to remove stretches, burned, or annealed strands.

  3. Square Cut the Conductor End

    Cut the conductor end squarely so that all strands are even, in lay, and free of burrs.

  4. Mark the Conductor for Insertion

    Measure the conductor for full insertion, which is one half the length of the splice. Mark this insertion distance clearly with tape or another suitable device.

  5. Wire Brush the Conductor End Section

    Using a bristle wire brush (e.g., T&B Cat. No. WWB1), thoroughly wire brush the end section of the conductor.

  6. Clean ACSR Conductor Core (If Applicable)

    For ACSR conductors only, thoroughly clean the portion of the ACSR stranding to be inserted into the automatic connector with a good quality aluminum conductor cleaner to remove lubricants from the steel core wire.

  7. Apply Oxide-Inhibitor

    Apply a coat of non-gritted oxide-inhibitor compound, such as Blackburn® CTB, to the conductor and then wipe off any excess.

  8. Re-brush Inhibitor-Coated Conductor

    Wire brush the inhibitor-coated conductor once again to ensure all oxides have been removed and the inhibitor reaches between the strands.

  9. Insert Conductor into Splice

    WARNING: DISCONNECT POWER BEFORE INSTALLATION TO AVOID RISK OF SHOCK. Do not remove the plastic strand guide or internal pilot cup from the splice. Insert the conductor into the splice with a smooth, straight, continuous thrust through the jaws until it hits the center stop. Do not twist or push partially and then continue. Check the previously made mark for full insertion; if insertion is incomplete, the conductor will not be gripped and will pull out easily.

  10. Apply Hand Set Tension

    Before releasing any blocks, apply a momentary “hand set” tension to the conductor to assure proper jaw gripping. Expect the conductor to move 1/4 inch to 1/2 inch from the end of the splice as tension is applied due to the sliding action of the gripping jaws; this is normal. DO NOT TAP THE SPLICE TO SET JAWS.
