Application
The strength of the aluminum stranded wire is small and cannot withstand large external forces. It is mainly used for transmission lines with small gear spacing and low force. The specification range of aluminum stranded wire is 16-800mm2. The long-term use temperature does not exceed 80 °C.
Standard
Conforms to the standard GB/T 1179-2008: round wire concentric stranded overhead conductor. (IEC61089, MOD)
