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.
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
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.
