BARE ACSR CONDUCTOR CABLE

ACSR Conductor

ACSR is a composite concentric-lay-stranded conductor. Galvanized steel strand or strands form the central core

of the conductor, around which is stranded one or more layers of EC Grade Aluminum wires. The steel core may

consist of a single strand or a concentric stranded cable of 7, 19, 37, or more wires. Numerous combinations of

aluminum and steel strands and layers are possible.

Applications

Conductor(AAC and ACSR) have been widely used in power transmission lines with various voltage levels,because

they have such good characteristics as simple structure,convenient installation and maintenance,low cost large tran

smission capacity.And they are also suitable for laying across rivers valleys and the places where special geograp

hical features exist.

Service Performance

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

2) Under the circumstance that rare climate is occurring 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 installation,the arc downing stress of all the conductors should be the same.With in the permissible distan ce of crossing buildings or dropping to the ground,the stress can be 10-15% higher than regular stress.
