The main classifications of bare conductor are AAC (All aluminum conductor), AAAC (All aluminum Alloy Conductor) or ACSR (aluminum conductor steel reinforced). AAC is most commonly found in urban areas with frequent supports and short spans. It is also used in coastal regions where salt in the air can cause corrosion - the all aluminum wire providing corrosion resistance - and specified for use in the railway industry for OHL electrification. AAAC tend to be specified where greater mechanical resistance is required and where there is a reduced sag characteristic. The ACSR, with its steel reinforcement provides additional strength and where the spans run for larger distances, such as across rivers.

Service Performance

(1).The permissible long-time operating temperature for aerial conductor is 70oC.

(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 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 conduct ors should be the same.With in the permissible distance of crossing buildings or dropping to the ground,the stress can be 10-15% higher than regular stress.

Material Standard Of All Aluminum Alloy Conductor

(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 IEC 60888:1987.

(3).Production can be arranged according to customers requirements for material standard,etc.

(*) Note: The values of current rating mentioned in above Table are based on wind velocity of 0.6 metre/second, solar heat radiation of 1200 watt/metre2, ambient temperature of 50° C & conductor temperature of 80°C.

Applications:

• Coastal and highly corrosive areas: have become the preferred or standard configuration for new transmission lines in these areas.
• Urban power grid and distribution lines: Due to their light weight, compact structure, aesthetic appearance (without steel core corrosion pollution), and minimal impact on electrolytic corrosion of surrounding metal facilities, they are increasingly used in overhead lines that are difficult to access in cities.
• Forest fire zone: The temperature of the arc bead generated by aluminum alloy wires during short circuit is relatively low, and it is not easy to ignite vegetation, which has certain fire safety advantages.
