AAC/TW

All Aluminum Conductor. Trapezoidal Shaped Aluminum Strands. Bare

Construction:

Conductor:Aluminum 1350-H19 trapezoidal shaped wires, concentrically stranded.

Applications and Features:

Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductor (AAC/TW) is designed for use as a bare overhead conductor. There are two designs of AAC/TW. One design gives an equal area of aluminum when compared to the standard AAC conductor sizes. The other design is conductor with overall outside diameters that are in fixed-increments. Use of this conductor in the equal area design allows comparable ampacity in a smaller diameter conductor when compared with standard AAC conductor. Use of this conductor in the fixed-increment diameter design allows more ampacity in an equal diameter conductor when compared with standard AAC conductor.
