ASTM BS DIN Standard All Aluminium Conductor 10mm2-800mm2
ASTM BS DIN Standard All Aluminium Conductor 10mm2-800mm2
All Aluminium Conductor are concentrically stranded.
This section deals with heat-treatable magnesium silicon type aluminium alloys to the applicable International Standard, the electrical and mechanical properties of which all fall within the values suggested by relevant standard.
Conductors to all other recognized specifications can also be supplied. The alloys referred to have higher strength but lower conductivity than pure aluminium.
Service Performance
(1). The permissible long-time operating temperature for aerial conductors is 70oC.
(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.
