JSK's bare ACSR conductors can meet any International Standard including ASTM, BS, DIN, IEC, NFC etc 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.
