SPECIFICATION FOR ACSS/TW CONDUCTOR

1.0 ITEM:

Conductor - ACSS/TW

2.0 SCOPE:

This specification covers shaped wire compact concentric-lay-stranded aluminum conductors, steel supported (ACSS/TW) made from trapezoidal shaped aluminum conductors and round Class A zinc-coated steel core wires.

3.0 USE:

The conductor furnished under this specification is to be used in electrical overhead distribution and transmission lines in the Central Texas area.

4.0 APPLICABLE STANDARDS:

Each of the following standards or the latest revision thereof shall become a part of this specification as well as any standards referred to herein.

4.1 American Society for Testing and Materials (ASTM) B857-02, Standard Specification for Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductors, Coated Steel Reinforced (ACSS/TW)

4.3 American Society for Testing and Materials (ASTM) B498/B498M-08, Standard Specification for Zinc-Coated (Galvanized) Steel Core Wire for Aluminum Conductors, Steel reinforced (ACSR)

5.0 GENERAL:

5.1 All ACSS conductors furnished under this specification shall in all respects

of 6 meet the requirements as stated in above referenced standards.

5.2 If there is any conflict between this specification and any of the aforementioned standards, then this specification shall govern.

5.3 ACSS/TW to be used for transmission line construction shall be indicated on the Bid Proposal and Purchase Order and the wire furnished thereunder shall meet the additional requirements stated herein.

6.0 RATINGS AND CLASSIFICATION:

6.1 The ACSS/TW described hereunder shall be classified as Class AA.

6.2 The ACSS/TW furnished under this specification shall be as specified under one of the following classifications:

Aluminum Aluminum Steel Core Stranding Stranding Stranding

Conductor Size Conductor Code Word No. of AL No. of No. of (kcmil) Type wires layers wires

959.6 16 Suwannee 22 2 7 1433.6 13 Merrimack 39 3 19

6.3 The number and diameter of aluminum and steel wires and the areas of cross section of aluminum wires shall conform to the requirements of ASTM B857 corresponding to the description given in Section 6.2 above.

6.4 The steel core shall be Class A zinc-coated unless specifically specified by purchaser to be stated otherwise.

7.0 CONSTRUCTION:

7.1 Aluminum

7.1.1 The trapezoidal aluminum 1350-0 wire used shall meet all of the requirements of the Standard Specification for Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductors, Coated Steel Reinforced (ACSS/TW), ASTM B857. The average conductivity of the finished aluminum wire strand shall be 63.0 % IACS or better.

of 6 7.1.2 The makeup and lay of conductor strands shall be such as to not have a tendency to untwist or spring apart when cut.

7.1.3 The surface of the conductor shall be free from points, sharp edges, abrasions, or other departures from smoothness or uniformity of surface contour that would tend to increase radio interference and corona loss. The conductor shall also be free of excessive amounts of die grease, metal particles, dirt, or other foreign matter.

8.0 DRAWINGS AND INSTRUCTION MANUALS: N-A

9.0 INSPECTIONS-TESTS:
