    introduction

    Aluminum conductor steel reinforced(ACSR)-IEC 61089

    Standard: IEC standard-IEC 61089 Application: Bare overhead transmission cable

    ZMS Cable provide Aluminum conductor steel reinforced(ACSR) by IEC standard -IEC 61089.

    Overview

    These conductors are formed by several wires of aluminum and galvanized steel, stranded in concentric layers. The wire or wires which form the core are made of galvanized steel and the external layer or layers are of aluminum. Normally these conductors have a Galvanized steel core of 1, 7, 19 or 37 wires, surrounded by concentric layers of aluminum wires. The diameters of the steel and aluminum wires can be alike or different. By varying the relative proportions of aluminum and steel ratios, the ideal conductor can be produced for any particular application. In this way , if a high tensile strength conductor is required, the number of steel wires can be increased until the required strength is reached . When a conductor with high current carrying capacity and a comparatively low strength is required, this is attained with high aluminum content.

    Properties

    In comparison with copper, these conductors have considerable technical and economical advantages in the installation of overhead lines. Its characteristics, and low weight, combined with its high break1ng strength, are gathered which makes it possible to have large span runs, without having to revert to excessive mechanical stresses or to heavy metallic Towers. Due to the greater diameter of the conductors, electric losses by the corona Effect are greatly reduced. By making use of these properties economical electric energy transmission is attained at very high voltages and distances. 

    Service Performance

    (1).The permissible long-time operating temperature for aerial conductor is 70oC.

    (2).Under the circumstance that rare climate is occuring and ice coverage rate low in heavy ice area,the biggest stress of cable at the lowest point of the sag should not exceed 60% of the short-time destructive power.

    (3).When connecting conductors,the conductor beside the connecting tube cant be prominent.Otherwise,the force on the operating conductors will be unbalanced.After connectors are install,the connecting tube should be painted by moisture-proof varnish in order to protect it from corrosion.

    (4).Under installaion,the arc downing stress of all the conductors should be the same.With in the permissible distance of crossing buildings or dropping to the ground,the stress can be 10-15% higher than regular stress.
