Details Of AAC ACSR and AAAC

 

Application

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.

 

Service Performance

1.     The permissible long-time operating temperature for aerial conductor is 70°C.

 

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 60% of the short-time destructive power.

 

3.     When connecting conductors,the conductor beside the connecting tube can’t 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 distance of crossing buildings or dropping to the ground,the stess can be 10-15% higher then regular stress.

 

Material Standard

1.      The hard aluminum conductor used for AAC and ACSR conforms to the standard GB/T 17048-1997(equivalent to IEC 60889:1987).
2.      The Zinc coated steel wire used for ACSR conforms to IEC60888:1987
3.      Production can be arranged according to customer’s requirements for material Standard
