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
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 tran
smission capacity.And they are also suitable for laying across rivers valleys and the places where
hical features exist.
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
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
