ACSR AAC AAAC Conductor with ASTM Standard

ACSR AAC AAAC Conductor with ASTM Standard

APPLICATIONS:

ACSR has the established reputation for economy and dependability in power

transmission lines. Also used for primary and secondary distribution lines. Wide

range of steel content from 7% to 40% can be achieved by different stranding, to

meet desired strength. Electrical losses by corona effect are greatly reduced, due to

the larger diameter size of this design. Economical transmission and distribution of

electrical energy can be achieved by ACSR, at very high voltages and distances.

SPECIFICATIONS:

ACSR Aluminum Conductors Steel Reinforced for High Voltage (HV) and Medium

Voltage (MV) Transmission Overhead Lines are usually manufactured according to

ASTM B232, BS 3242, DIN 48204, TS IEC 1089

CONSTRUCTION:

ACSR is a composite concentric-lay-stranded conductor. Galvanized steel strand or

strands form the central core of the conductor, around which is stranded one or

more layers of EC Grade Aluminium wires. The steel core may consist of a single

strand or a concentric stranded cable of 7, 19, 37, or more wires. Numerous

combinations of aluminum and steel strands and layers are possible.

FEATURES AND BENEFITS:

ACSR conductors are recognized for their record of economy, dependability and

favorable strength / weight ratio. ACSR conductors combine the light weight and

good conductivity of aluminum with the high tensile strength and ruggedness of

steel. In line design, this can provide higher tensions, less sag, and longer span

lengths than obtainable with most other types of overhead conductors. The steel

strands are added as mechanical reinforcements. The cross sections above

illustrate some common stranding. The steel core wires are protected from

corrosion by galvanizing.
