// Aluminium Conductor Steel-Reinforced (ACSR)

Description
The conductor consists of Aluminium wires and Zinc coated steel wires, built up in concentric layers. The centre wire or wires are Zinc coated and the outer layer or layers are of Aluminium. In case required, neutral grease shall be applied between the layers of ACSR except the outer layer.

Standard
IS 398 part 2 and 5, BS 215 part 2, EN 50182, ASTM B232, IEC 61089 and other International Specifications. The requirement/specifications given by the purchaser are also taken care of.

Characteristics
Aluminium strand outer layer/layers are formed with centre core of single/stranded galvanized steel wires

Can be suitably designed for increased mechanical strength needs by increasing number of steel wires

Can be suitably designed for average mechanical needs by using higher aluminium & lower steel contents

Suited for large spans with metal towers

High mechanical strength to weight ratio

ACSR yield less sag at a given tension

Toughness is suited to extreme wind loads

Corona losses are least due to large diameters

Application
ACSR bare conductors are used for overhead high tension power transmission lines having long spans.
