Specification

ACSS AW Aluminum Conductor Aluminum Clad Steel Supported Bare Overhead Concentric Lay Stranded Conductors

Application:

Generally used as bare overhead transmission lines. Maximum operating temperature:* ACSS/AW 250 °C 

Also Known As:

ACSS AW Conductor, Aluminum Clad Steel Wire, Overhead Transmission Lines, High-Temperature Conductors, Electrical Grid Upgrades, Concentric Lay Stranding, Bare Overhead Conductors, High Tension Power Lines, Steel Supported Aluminum, ACSS Sag Properties

Standards:

ASTM B856: Concentric-Lay-Stranded Aluminum Conductors, Coated Steel Supported (ACSS).
ASTM B609: Aluminum 1350 Round Wire, Annealed and Intermediate Tempers.
ASTM B502: Specification for Aluminum-Clad Steel Core Wire for Aluminum Conductors, Aluminum-Clad Steel Reinforced. 

Conductor: 

Aluminum alloy 1350-0, fully annealed (0 temper). 
Steel Core: Aluminum-Clad steel core wire. 

Stranding: 

1350-0 wires concentrically stranded, consisting of one or more layers of wire helically wrapped around a stranded Aluminum-Clad Steel core wire. 

Features:

• ACSS has at least 63.0% IACS conductivity due to their “deadsoft” (fully annealed) aluminum strands.
• For the same reason, ACSS cables can be operated at temperatures of maximum 250 °C without loss of strength.
• Since the mechanical tension applied to the aluminum strands is low, the ACSS self damping characteristic is high.
• This allows ACSS cables to be installed at high unloaded tensions without the need for separate Stockbridge dampers.
