Product Description

 Aluminum Conductor Steel Reinforced (ACSR) Cables

1.  Application: 

2. 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.

2. 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.

3. Approvals

4. 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 consist 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. The illustration below shows typical standard sizes and stranding patterns.

1.  Protection against corrosion: 

A coating of non-oxidizing grease is normally applied to the steel cores of all conductors, in addition to the protection offered by the galvanizing of the steel wires. One or more layers of the aluminium wires can, if required, be supplied partially or fully greased. OCI ensures complete freedom from contamination by other metals during the entire manufacture of ACSR conductors.
