Phosphating Steel Wire for Optical Cable - Top 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 (FAQ)
What is the main role of the stiffener in an optical cable?
The role of the stiffener is to act as a strengthening part that enhances the tensile properties of the cable.
Why is phosphating steel wire preferred over galvanized steel wire?
The zinc on galvanized steel wire reacts easily with acid in the oil paste, resulting in hydrogen loss. Phosphating steel wire avoids this issue, meets process requirements, and keeps costs down.
Does the steel wire cause hydrogen loss or rust after cabling?
No, after cabling, the phosphating steel wire maintains high strength and will not increase hydrogen loss or rust.
How is the plastic layer applied to the optic cable steel wire?
The plastic layer is evenly coated onto the surface of the galvanized or phosphating steel wire using an extrusion process, which provides higher adhesion to the outer sheath.
What are the additional benefits of using plastic-coated steel wire?
In addition to high strength and toughness, the plastic coating offers electrical insulation, decorative appeal, and excellent resistance to corrosion from acid, alkali, salt, and other media.
