7x0.33 Galvanized Steel Strand 1.0mm 1.35mm For Telecommunications

Product Introduction

7x0.33 galvanized steel stranded wire for fiber optic cables is a reinforcement component specially designed for fiber optic cables. It is made by twisting 7 galvanized steel wires with a diameter of 0.33mm. Its main function is to provide mechanical support for the fiber optic cable core, improve the overall tensile strength and bending resistance, and extend the service life of the cable by leveraging the anti-corrosion properties of the galvanized layer.

Product Advantages

• Precise matching: Designed with a single wire diameter of 0.33mm, it perfectly adapts to the reinforced core channel of conventional indoor and outdoor fiber optic cables, without causing deformation of the cable core due to excessive size Lightweight support: While providing sufficient tensile strength, it maximizes the control of its own weight, avoiding increasing the overall load of fiber optic cables and reducing the difficulty of laying Anti corrosion protection: The galvanized layer forms a dense protective barrier, which can effectively resist corrosive factors such as moisture, salt alkali, industrial waste gas, etc., extending the service life of the cable Flexibility balance: The 7-strand twisted structure has better flexibility compared to a single thick steel wire, making it easy to lay cables in bending and twisting scenarios without damaging the internal optical fibers

Applications

Outdoor overhead optical cable: As the main reinforcement component, it can withstand the weight of the optical cable and external forces such as wind and ice loads Pipeline optical cable: Enhance the tensile strength of the optical cable during dragging and threading in the pipeline to prevent cable core breakage Indoor cabling optical cables: Improve the mechanical stability of optical cables in bending and moving scenarios, and protect optical fibers from damage Special optical cable: Suitable for special scenarios such as submarine optical cables and mining optical cables that require high mechanical and anti-corrosion performance Product Certification Our steel wire rope meets international production standards and has obtained multiple certifications such as SGS, CE, ISO, etc.
