All correspondence must be made through the Vendor Portal. Specifications include, but are not limited to: This specification describes the requirements for the design, manufacture and delivery of twisted pair (TP) conductor consisting of two (2) bare concentric-lay stranded 397.5 26/7 (IBIS) Aluminum Conductor Steel Reinforced (ACSR) conductors twisted around each other and made from round aluminum wires and round zinc coated steel core wires. The ACSR/TP conductor will be used as phase conductors. 2.2.1. Each ACSR conductor of the twisted pair shall be Class AA stranded concentric lay. 2.2.2. The aluminum strands of the ACSR conductor shall meet the requirements of ASTM B230 for aluminum 1350 H-19, extra hard, round wire. 2.2.3. The volume conductivity and electrical resistivity of the aluminum strands shall be as set forth in Table 3, ASTM B230/B230M-07. 2.2.4. The steel strands of the ACSR conductor shall be zinc-coated (Class A weight coating) in accordance with ASTM B498.2.2.5 The outer layer of strands of each ACSR conductor shall have a standard right hand lay. The conductor shall comply with the requirements of ASTM B232.
