Phosphating Steel Wire for Optical Cable - China Suppliers & Factory for Enhanced Tensile Strength
Product Advantage
The role of the stiffener is to enhance the tensile properties of the cable. Steel wire as a strengthening part, its cost, processing technology and performance indicators are easy to meet the production needs of optical cable. In addition, the steel wire of optical fiber and cable is not easy to rust and will not cause hydrogen damage. Fiber optic cable steel wire needs to be treated, the cost of stainless steel wire is higher, the zinc on the surface of galvanized steel wire is easy to react with acid in the oil paste resulting in the loss of hydrogen, so the general use of phosphating steel wire, which not only ensures the process requirements, but also reduces the cost.
Product Features
Cable strength member (phosphating steel wire) is pointed to the phosphating steel wire with brown surface. In the cable, it plays a part of support, tensile. After cabling, steel wire would not increase hydrogen loss, rust but high strength.
The steel wire used in optic cable is galvanized or phosphating wire, and the plastic layer is evenly coated on the surface of the steel wire by extrusion process. After cabling, the adhesion of the wire and outer sheath is higher. It is widely used in the outdoor self-bearing fiber optic cable.
In addition to the steel wire high strength, high toughness, the coated steel wire has performance of decoration, electrical insulation and other comprehensive performance concurrently at the same time, because of the plastic coating layer with performance of acid, alkali, salt and other media corrosion ability.
Frequently Asked Questions
What is the role of the stiffener in the fiber optic cable?
The role of the stiffener is to enhance the tensile properties of the cable, playing a crucial part in providing support and tensile strength.
Why is steel wire used as a strengthening part?
Steel wire is utilized because its cost, processing technology, and performance indicators easily meet production needs. Furthermore, it is not prone to rusting and does not cause hydrogen damage.
Why is phosphating steel wire preferred over galvanized steel wire?
The zinc on the surface of galvanized steel wire can react with the acid in the oil paste, leading to hydrogen loss. Phosphating steel wire prevents this reaction, ensures processing requirements are met, and helps reduce costs.
How is the plastic layer applied to the steel wire?
The plastic layer is evenly coated on the surface of the steel wire using an extrusion process. This ensures higher adhesion between the wire and the outer sheath after cabling.
What additional benefits does the plastic-coated steel wire offer?
In addition to high strength and toughness, the plastic coating provides excellent electrical insulation, decoration, and resistance to corrosion from acid, alkali, salt, and other media.
