The reinforcement of conductors, such as ACSR, ACSS, and AACSR, to withstand mechanical forces is usually achieved through the integration of galvanized steel wires. Galvanization involves the application of a protective coating onto bare steel wires to prevent rusting and oxidation. As stipulated by the ASTM (American Society for Testing and Materials) standard, the use of galvanized steel wires is a requisite in the construction of bare overhead conductors.

The reinforcement of conductors, such as ACSR, ACSS, and AACSR, to withstand mechanical forces is usually achieved through the integration of galvanized steel wires. Galvanization involves the application of a protective coating onto bare steel wires to prevent rusting and oxidation. As stipulated by the ASTM (American Society for Testing and Materials) standard, the use of galvanized steel wires is a requisite in the construction of bare overhead conductors. These galvanized wires are categorized into three classes, namely A, B, and C, based on the density of the coating on the wire's surface. Class A, characterized by the most common coating density, is frequently employed.
In compliance with recognized industry standards such as ASTM, BSEN (British Standards for Electrotechnical Products), DIN (Deutsches Institut für Normung - German Institute for Standardization), and IEC (International Electrotechnical Commission), the physical, chemical, and mechanical properties of galvanized steel wires are rigorously assessed. This meticulous evaluation ensures that the wires adhere to predefined quality benchmarks.
The prevalence of galvanized steel wires as reinforcers in overhead conductors with steel cores is attributed to their compelling advantages. These include commendable efficiency, cost-effectiveness, and streamlined production processes. Collectively, these attributes solidify the status of galvanized steel wires as the most widely adopted choice for enhancing the mechanical integrity of overhead conductors, ultimately contributing to the reliability and functionality of power transmission and distribution systems.
