ACSS :Aluminum Conductor. Steel Supported.
STANDARDS
ACSS conductor meets or exceeds the following ASTM standards:
l      B-341 Aluminum-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced.
 
l      B-500 Metallic Coated Stranded Steel Core For Aluminum Conductors, Steel Reinforced.
 
l      B-609 Aluminum1350 round Wire, Annealed and Intermediate Tempers, for Electrical Purposes
 
l      B-802 Zinc-5% Aluminum-Mischmetal Alloy-Coated Steel Core Wire for Aluminum Conductors, Steel
 
Reinforced.
 
l      B-803 High-Strength Zinc-5% Aluminum-Mischmetal Alloy-Coated Steel Core Wire for Aluminum and
 
Aluminum-Alloy Conductors, Steel Reinforced.
 
l      B-856 Concentric-Lay-Stranded Aluminum Conductors, Coated Steel Supported(ACSS)
 
 
Applications
ACSS is used for overhead distribution and transmission lines. It is designed to operate continuously at elevated temperatures up to 250°C without loss of strength; it sags less than a comparable ACSR under electrical loadings; it is self-damping if prestretched during installation; and its final sags are not affected by long term creep of aluminum. The advantages make ACSS especially useful in reconductoring applications requiring increased current with existing tensions and clearances, new line applications where structures can be economized because of reduced conductor sag, new line applications requiring high emergency loadings, and lines where aeolian vibration is a problem.
