Instruction for Bare Conductor
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
The permissible long-time operating temperature for aerial conductor is 70°C.
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.
Material Standard
The hard aluminum conductor used for AAC and ACSR conforms to the standard GB/T 17048-1997(equivalent to IEC 60889:1987).
The Zinc coated steel wire used for ACSR conforms to IEC60888:1987
Production can be arranged according to customer's requirements for material Standard
