Phosphated steel wire is commonly used as a strengthening material for optical cables. It helps to provide mechanical support and increase the tensile strength of the cable. Polyvinyl chloride resins are often used as a general-purpose material for various applications, including cable insulation and jacketing. In combination with the phosphated steel wire, they can provide a reliable and durable solution for optical cable suspension. A professional manufacturer with expertise in these materials can ensure high-quality products that meet industry standards.
