ACSR Conductor

ACSR have been widely used in power transmission lines with various voltage levels, and also used in power lines across great rivers, havey ice area, etc. With special geographical situation. The cables have excellent advantages of high strength, large current carrying capacity and good catenary property as well as wear-resistance, anti-crush() and corrosion-froof with simple structure, convenient installation and maintenance, low cost for the line, large transmission capacity.Construction The mixed construction of ACSR makes it a very flexible medium from a desigh point of view. By varying the relative proportins of aluminium and steel the ideal conductor for any particular application can be produced. Generally, ACSR consists of a galvanized steel core of 1 wire, 7 wires or 19 wires surrounded by concentric layers of aluminium wire. When a conductor with a high current carrying capacity and comparatrively low strengh is required, special constructions are available with a high aluminium content.Protection against Corrosion A coating of non-oxidizing grease is normally applied to the steel cores of all conductors, in addition to the protection offered by the galvanizing of the steel wires. One or more layers of the aluminium wires can, if required, be supplied partially or fully greased.
