ACSR Aluminum Conductor Steel ReinforcedACSS Aluminum Conductor Steel Supported

Overview

DESCRIPTION

ACSS is a concentric-lay stranded composite conductor made up of a core of galvanized steel strands and one or more layers of annealed or soft 1350-0 Aluminum. The steel core wire is Class A galvanized zinc-coated steel which, due to the annealed or soft temper Aluminum, carries most or all of the mechanical load of the conductor. Upon request the steel core is available in High strength.

APPLICATION

Aluminum conductor steel supported (ACSS) cable is used for overhead transmission lines. ACSS is designed to operate continuously at higher temperatures up to 250ᵒC without loss of strength, which allows for a significant increase in current carrying capacity over ACSR. ACSS is self-damping, sags less than ACSR under emergency electrical loadings, and its final sags are not affected by the long term creep of aluminum. These advantages make ACSS useful in new line applications where structures can be optimized due to the reduced conductor sag or where high emergency loads may be required; or in lines where Aeolian vibration is a problem. Existing lines can be re-conductored using ACSS to allow for increased current using the existing clearances and tensions.

CONSTRUCTION

ACSS is a composite concentric-lay stranded conductor. Steel strands form the central core of the conductor with two or more layers of aluminum 1350-O wire stranded around it. The steel core carries most or all of the mechanical load of the conductor due to the “O” temper (fully annealed or soft) aluminum. Steel core wires are protected from corrosion by a zinc-5% aluminum-mischmetal alloy coating. For aluminum-clad (AW) ACSS, please refer to the ACSS/AW catalog sheet. Corrosion protection should be selected to suit the environment to which the conductor will be exposed.

ADDITIONAL STANDARDS

ACSS conductor meets or exceeds the following ASTM specifications:
• B500 – Metallic Coated Stranded Steel Core for Use in Overhead Electrical Conductors.
• B609 – Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes.
• B802 – Zinc-5% Aluminum-Mischmetal Alloy-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced
(ACSR).
• B803 – High-Strength Zinc-5% Aluminum Mischmetal Alloy-Coated Steel Core Wire for Use in Overhead Electrical Conductors.
• B856 – Concentric-Lay-Stranded Aluminum Conductors, Coated Steel Supported (ACSS).
• B958 – Extra-High-Strength and Ultra-High-Strength Class A Zinc-5% Aluminum-Mischmetal Alloy-Coated Steel Core Wire for Use in Overhead Electrical Conductors.
The strandings available are identical to those listed in ASTM specification B232.

What’s The Advantages of ACSS Conductor?

● Improved self-damping characteristics and high degree of resistance to vibration fatigue.
● Can operate continuously at high temperatures up to 250°C (482°F) with appropriate steel core coating v/s 100°C (212°F) for standard ACSR, hence can carry twice as much current as ACSR conductor.
● No creep.
● Less susceptible to Aeolian vibration fatigue due to very low mechanical load on the annealed aluminium wire.
● Requires conventional installation techniques.
● Allows for lower overall transmission cost.
