This standard applies to hot-dip galvanized and zinc-aluminum alloy platings low-carbon steel wires used for the protection of submarine and underground cables for communication, automatic control or power. The standard specifies the classification and marking of steel wires, the content of orders, technical requirements, test methods, inspection rules, and Encasement, marking and mass certificates. By clarifying the technical indicators and mass requirements of steel wires, it ensures that they have good corrosion resistance and mechanical strength in harsh environments, providing reliable technical support for the production and application of armored cables.
