Astm Bs Din All Aluminium Conductor For Aerial Cable

ASTM BS DIN All Aluminium Conductor For Aerial Cable

A concentric lay-stranded Aluminium Conductor ( AAC) is made up of one or more strands of hard-drawn 1350 aluminum alloy. These conductors are used in low, medium, and high-voltage overhead lines. AAC has seen extensive use in urban areas where spans are usually short but high conductivity is required. The excellent corrosion resistance of aluminum has made AAC a conductor of choice in coastal areas. Because of its relatively poor strength-to-weight ratio, AAC had limited use in transmission lines and rural distribution because of the long spans utilized.

Service Performance

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

(2). Under the circumstance that rare climate occurs and high ice coverage rate, the biggest stress of cable at the lowest point of the sag should not exceed 60% of the short-time destructive power.
