Aluminum Conductor Steel Reinforced (ACSR) Cable – Overhead Power Transmission – BS, IEC, ASTM, DIN, JIS

Overhead Line
Description
Specifications

Product Overview

ACSR conductors are widely used for electrical power transmission over long distances, since they are ideal for long overhead lines spans. They are also used as a messenger for supporting overhead electrical cables.

Standards: Basic design to BS 215‑2 / BS EN 50182 / IEC 61089 / ASTM B 232 / B 232M / DIN 48204 / JIS C 3110 / AS 3607 standards.

Conductor Type Aluminum Conductor Steel Reinforced (ACSR)
Construction Concentric layers of aluminium wires over galvanized steel core
Applications Long span overhead transmission, distribution, messenger wire

Construction

ACSR conductors are formed by several wires of aluminium and galvanized steel, stranded in concentric layers. The wire or wires which form the core are made of galvanized steel and the external layer or layers are of aluminium. Galvanized steel core consists normally of 1, 7 or 19 wires. The diameters of steel and aluminium wires can be the same, or different.

By varying the relative proportions of aluminium and steel, the required characteristics for any particular application can be reached. A higher U.T.S. can be obtained by increasing steel content, and a higher current carrying capacity by increasing aluminium content.

ACSR has long been widely used as overhead high tension transmission lines and has an established reputation for economy and dependability.
