Overhead Electrical Power transmission line ACSR Code 240/40 overhead conductor DIN Standard

APPLICATION

ACSR conductor consists of aluminium and galvanized steel, stranded in concentric layers.. Galvanized steel core consist normally of 7, 19, 37 and 61 wires. The diameters of steel and aluminium wires c an be the same, or different. ACSR
Conductor is available in a wide range of steel, containing carbon from 0.5% to 0.85 %. The higher strength ACSR
The principal advantage of these conductors are high tensile strength so that they are used for longer spans with less supports. they are used for river crossings, overhead ground wires, installations involving extra long spans etc.

STANDARD

Basic design to BS 215-2 / BS EN 50182 / IEC 61089 / ASTM B 232/B 232M / DIN 48204 / JIS C 3110 standards.

Key Benefits

• ACSR Conductor has high Tensile Strength.

• Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.

• Additional corrosion protection is available through the application of grease to the core or infusion of the complete

cable with grease
