TransPowr® ACCC®-TW Bare Overhead Conductor (Canada)

TransPowr® ACCC®/TW is an aluminum conductor composite core trapezoidal concentric-lay-stranded conductor. The aluminum strands are trapezoidal in shape and enable a more compact placement of the aluminum strand wires. ACCC/TW conductors are designed to maintain the same overall diameter as a conventional round wire ACSR. The compact trapezoidal conductors, coupled with a smaller composite core, result in a TW conductor that has approximately 28% more aluminum cross-sectional area than ACSR. The design features follow the applicable requirements of ASTM B857 (Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductors, Coated-Steel Supported (ACSS/TW)). The annealed aluminum strand wires are in accordance to ASTM B609. The composite core strength member is a proprietary high-strength carbon and glass fiber composite core in accordance to ASTM B987, around which are stranded two, three or four layers of the annealed 1350 aluminum wires.
