Detailed Product Description

Applications
Aluminium conductor steel wire reinforced wire used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.
ACSR 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.
