    • Name: AAAC conductor with ASTM B399 standard
    • Views : 301

        Application

      Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a high-strength aluminum alloy to achieve a high strength-to-weight ratio; affords better sag characteristics. Aluminum alloy gives AAAC higher resistance to corrosion than ACSR.

        Standard

      AAAC bare conductor meets or exceeds the following ASTM specifications:

      B-398 Aluminum Alloy 6201-T81 Wire for Electrical Purposes

      B-399 Concentric-Lay-Stranded 6201-T81 Aluminum Alloy Conductors

           Note: this AAAC bare overhead conducotr also can be manufactured according to your special request.

        Construction

      Standard 6201-T81 high strength aluminum conductors, conforming to ASTM Specification B-399, are concentric-lay-stranded, similar in construction and appearance to 1350 grade aluminum conductors. Standard 6210 alloy conductors are similar to other alloy conductors commercially known as Ardival, Aldrey or Almelec. They were developed to fill the need for an economical conductor for overhead applications requiring higher strength than that obtainable with 1350 grade aluminum conductors, but without a steel core. The DC resistance at 20 °C of the 6201-T81 conductors and of the standard ACSR of the same diameter are approximately the same. Conductors of the 6201-T81 alloys are harder and , therefore, have a greater resistance to abrasion than conductors of 1350-H19 grade aluminum.

      Note:

       1. Resistance is calculated using ASTM standard increments of stranding and metal conductivity of 52.5% IACS, AC resistance at 60Hz

       2. Current ratings are based on 75°C conductor temperature, 25°ambient,2ft/s wind, 96/watts/sq.foot sun,.05 coefficients of emissivity and absorption.
