| ACSR Aluminum Conductor Steel Reinforced | |

|
Aluminum conductor, steel reinforced (ACSR) has long been the backbone of overhead transmission and distribution systems. It is common in all sizes from 6 AWG through 2000 kcmil, and can be even larger. It is made in a variety of constructions, depending on the conditions of use, but all constructions are characterized by the use of hard-drawn, aluminum alloy 1350 wires stranded over a galvanized steel wire core. Including a larger steel core can strengthen the conductor, thereby reducing the number of poles or towers required. |

The ACSR conductors described here are suitable for installation in all practical spans on transmission towers, wood poles and other structures, ranging from long distance EHV transmission lines to sub-service spans at distribution or utilization voltages on private premises. The choice of conductor size, type and strength should take into account factors such as electrical load, voltage regulation, corona losses, ice and wind loading, extreme temperatures and vibration. ECS is prepared to assist in the evaluation of these factors as they apply to specific installations. |
