What governing standard and construction define ACSR (ACSR (Aluminum Conductor Steel Reinforced) Overhead Transmission Conductor)?

ACSR (ACSR (Aluminum Conductor Steel Reinforced) Overhead Transmission Conductor) is manufactured in accordance with IEC 61089 / ASTM B232 / BS EN 50182 for Up to 500 kV AC service over -40 °C to +80 °C. Its 2-layer construction comprises galvanized high-tensile steel core, concentric 1350-h19 aluminum conductive layers.

What is the minimum bending radius and installation temperature for ACSR?

The minimum installed bending radius for ACSR is 20 × OD across its continuous operating temperature range of -40 °C to +80 °C, ensuring mechanical and dielectric stability without conductor or insulation strain.

How are the concentric layers of ACSR arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Galvanized high-tensile steel core (Class A zinc-coated or aluminum-clad steel core strand (1, 7 or 19 wires)); (02) Concentric 1350-H19 aluminum conductive layers (Hard-drawn 1350-H19 electrolytic aluminum wires stranded in reversed layers).

What factory test certificates are supplied with ACSR?

Every production drum or spool of ACSR undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per IEC 61089 / ASTM B232 / BS EN 50182, and is delivered with an EN 10204 3.1 factory test certificate.
