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 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.

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 DC&branded;/km(*0oC). The resistivity of the hard aluminum

wire for stranded wires is not greater than *8.**4 n&branded;. 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.
