Aluminum conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purity aluminium, chosen for its good conductivity, low weight, low cost, resistance to corrosion and decent mechanical stress resistance.

ACSR/SD - Sometimes called SDC (Self Damping Conductor), is a concentric ordinary stranded, self damping conductor created to manage aeolian type vibration in overhead transmission lines by internal damping. Self damping conductors includes a main core of several round steel wires surrounded by 2 layers of trapezoidal shaped aluminum wires.

ACSR/SD conductors are utilized for overhead transmission lines to manage aeolian vibration. These conductors feature a steel core surrounded by two layers of trapezoidal-shaped aluminum wires. The design includes a gap between the core and the aluminum layers, which provides self-damping characteristics and eliminates the need for additional ...

ACSR/SD - Sometimes called SDC (Self Damping Conductor), ACSR/SD is a concentric lay stranded, self damping conductor designed to control aeolian type vibration in overhead transmission lines by internal damping. Self damping conductors consists of a central core of one or more round steel wires surrounded

ACSR/SD conductors are used for overhead transmission lines to control Aeolian vibration. Options: • •High-conductivity aluminum (/HC) (62.2% IACS) • Regular-strength Class C galvanized steel core (/GC2) • High-strength Class A galvanized steel core (/GA3 to ASTM B606) • Extra-high-strength Class A galvanized steel core (/GA4 to ASTM ...

Self-Damping Aluminum Conductor Steel Reinforced (ACSR/SD) cable permits longer spans, provides increased reliability, and lowers overall line cost. It also reduces sag, as well as cuts ice and wind loads.

TransPowr® ACSR-SD Bare Overhead Conductor (US)* Product description ACSR/SD conductors are manufactured with two layers of 1350 H19 trapezoidal-shaped aluminum wires concentrically stranded around a steel core of round coated steel wires.

2022年12月1日 · Note 1: ACSR/SD is designed to control aeolian vibration by integral damping. The conductors consist of a central core of a round steel wire or wires surrounded by two layers of trapezoidal aluminum 1350-H19 wires or two layers of trapezoidal aluminum 1350-H19 wires and one layer of round aluminum 1350-H19 wires ( Fig. 1 ).

shaped aluminum wires in ACSR/SD are separated by a gap designed to provide self-damping characteristics to control Aeolian vibration—eliminating the need for vibration dampers. This EPD includes results for the following products: POTOMAC/ACSR/TW/GA2/NS
