Phosphating Wire for Optical Cable - High-Quality Steel from China Suppliers and Factory
Product Advantage
Product Features
1. 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.
2. 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.
3. 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 primary role of the stiffener in the cable?
The role of the stiffener is to enhance the tensile properties of the cable, providing essential support and strength.
Why is steel wire commonly chosen as a strengthening part?
Steel wire is chosen because its cost, processing technology, and performance indicators easily meet production needs. It is also highly resistant to rust and does not cause hydrogen damage.
Why is phosphating steel wire preferred over galvanized steel wire?
The zinc on galvanized steel wire can react with acid in the oil paste, leading to hydrogen loss. Phosphating steel wire avoids this issue, ensures process requirements, and reduces costs compared to stainless steel.
What exactly is a cable strength member?
A cable strength member typically refers to phosphating steel wire with a brown surface. It supports the cable and provides tensile strength without increasing hydrogen loss or rusting after cabling.
How is the plastic layer applied to the steel wire in optic cables?
The plastic layer is evenly coated onto the surface of the galvanized or phosphating steel wire using an extrusion process, which ensures high adhesion between the wire and the outer sheath.
What additional benefits does coated steel wire offer?
Beyond high strength and toughness, the plastic coating offers decorative properties, electrical insulation, and excellent resistance to corrosion from acid, alkali, salt, and other media.
