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
concentricstranded cable of 7, 19, 37, or more wires. Numerous
combinations of aluminum and steel strands and layers are possible.

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 transmission capacity.And they are also
suitable for laying across rivers valleys and the places where
special geographical features exist.
(1). The permissible long-time operating temperature for aerial
conductor is 70℃.
(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
(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 distance of
crossing buildings or dropping to the ground, the stress can be
10-15% higher than regular stress.
