AAC,AAAC,ACSR,ACAR bare conductor

Brief Instruction for Bare conductor

1.Applications

Conductor(AAC,AAAC 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.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.

Construction of All Aluminum Conductor and Aluminum Conductor Steel Reinforced
