1. Applications of HDA Conductor
AAC AAAC ACSR Conductor have been widely used in power transmission
lines with various voltage levels, because they have such good
character is tics as simple structure,convenient installation and
maintenance,low cost and large transmission capacity.They are also
suit able for laying across rivers,valleys and the places where
special geographical features exist.
2. Service Performance
(1).The permissible long-time operating temperature for aerial
(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 exceed60%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.
(1).The electrical performance of AAC Conductor and ACSR Conductor
is indicated in DC/km(20oC).There sistivity of the hard aluminum
wire for stranded wires is not greater than 28.264 n.m of
international standard value.
(2).The rated tensile strength of AAC Conductor is denoted with the
result of total cross-section of all aluminum conductors multiplied
by min. tensile of corresponding size specified in the standard for
