Phosphated steel wire for optical cables

When installing optical cables it is necessary to hang them on utility poles or walls. During this process the optical cable needs to withstand a certain amount of tension to avoid swinging or shearing. If the skeleton material of the optical cable does not have sufficient mechanical strength and tensile performance the optical cable is prone to damage and data transmission interruption. Therefore in order to enhance the mechanical strength and corrosion resistance of optical cables phosphated steel wire is usually used as the skeleton material in optical cables. Phosphated steel wire for optical cables is a type of steel wire coated with a phosphating layer on the surface which has good corrosion resistance while maintaining the strength of the steel wire itself. Therefore the use of phosphated steel wire in optical cables can effectively prevent the steel wire from being corroded in harsh environments such as rainwater and reduce the maintenance cost of optical cables.
