The scope and normative reference document 1.1 of aluminum magnesium silicon alloy round wires for overhead power transmission cables. This standard is applicable to two types of aluminum magnesium silicon alloy round wires with different mechanical and electrical properties, used for the production of overhead power transmission cables. And the mechanical and electrical properties of aluminum magnesium silicon alloy circular wires with a diameter range of 1.50 mm to 4.80 mm were specified. These two models are LHA1 and LHA2, respectively. The product representation method can be found in Appendix A. 1.2 Normative references The clauses in the following documents become the clauses of this standard through the reference surface of this standard. For dated reference documents, all subsequent modification orders (excluding corrected content) Neither the revised version nor the revised version is applicable to this standard. Therefore, all parties who have reached agreements based on this section are encouraged to study whether the latest versions of these documents can be used. For undated references, the latest version applies to this standard.
