ALUMINUM CONDUCTOR STEEL REINFORCED CONDUCTORS

ACSR is a composite, concentrically stranded conductor in which the light weight and good conductivity of aluminium are combined with the high tensile strength of steel. It is composed of one or more layers of EC grade hard-drawn aluminium wires helically stranded around an inner core of high strength zine-coated steel wires. The inner steel core may be a single zinc-coated steel wire, or concentrically stranded of one or more layer of zinc-coated steel wires.
ACSR is a concentrically stranded conductor composed of one or more layers of hard-drawn 1350H19 aluminum wire stranded with a high strength coated steel core. The core maybe single wire or stranded depending on the size.The proportions of aluminum and steel can be varied to obtain the relation between current-carrying capacity and mechanical strength best suited to each application. The Core of Conductor is made of galvanized steel wires drawn from high carbon steel rods. The No. of steel wire vary from 1 to 7. The other layers of Conductors are formed by hard drawn Aluminum Wires drawn from E.C. Grade Aluminum, successive layers containing 6, 12, 18, 24 wires depending upon size of Conductors.
