This standard specifies the electrical and mechanical properties, testing, packaging, etc. of aluminum clad steel wires for electrical purposes. This standard applies to circular hard aluminum clad steel wires with different electrical and mechanical properties for electrical purposes before stranding, and their diameter ranges are shown in Table 4. The wooden standard includes the application of reinforced cores for aluminum stranded wire and aluminum clad steel wires for all aluminum clad steel stranded wires. This standard does not include re drawn wires. 2 Normative References: The clauses in the following documents become clauses of this standard through reference in this standard.
