All Aluminum Conductor (AAC AAAC) & Aluminum Conductor Steel
Reinforced (ACSR)
Product Description
1. Applications
Conductor(AAC and ACSR) have been widely used in power transmission
lines with various voltage levels, because theyhave 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.
2. Service Performance
(1). The permissible long-time operating temperature for aerial conductor is *0oC.
(2). Under the circumstance that rare climate is occuring and ice coverage rate low in heavy ice area, the biggest
stress of cable at the lowest point of the sag should not exceed *0% 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 installaion, 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 ****5% higher than regular stress.
3. Product Performance
(1). The electrical performance of AAC and ACSR is indicated in DCΩ/km(*0oC). The resistivity of the hard aluminum
wire for stranded wires is not greater than *8.**4 nΩ. M of international standard value.
(2). The rated tensile strength of AAC 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 aluminum wire.
(3). The rated tensile strengh of ACSR is denoted with sum of all aluminum conductorstensile strength and steels
tensile strength.
A. The tensile strength of all aluminum conductors is denoted with the result of all cross-sections of aluminum
conductors multiplied by min. Tensile strength of corresponding size specified in the standard for aluminum wire.
B. The tensile strength of all steel wire is denoted with the result of all cross-sections of steel wires
multiplied by the stress at 1% elongation of corresponding size specified in the standard for steel wire.
4. Material Standard
(1). The hard aluminum conductor used for AAC and ACSR conforms to the standard GB/T *********7(equivalent to IEC
****9: ***7).
(2). The zinc coated steel wire used for ACSR conforms to IEC ****8: ***7.
(3). Production can be arranged according to customers requirements for material standard, etc.
