336.4 MCM Oriole ACSS AW Aluminum Conductor Steel Supported Aluminum Clad

Application:

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

Also Known As:

336.4 MCM ACSS AW Conductor, 336.4 MCM Aluminum Clad Steel Wire, 336.4 MCM Overhead Transmission Lines, 336.4 MCM High-Temperature Conductors, 336.4 MCM Electrical Grid Upgrades, 336.4 MCM Concentric Lay Stranding, 336.4 MCM Bare Overhead Conductors, 336.4 MCM High Tension Power Lines, 336.4 MCM Steel Supported Aluminum, 336.4 MCM 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.
