Galvanized Steel Wire for Optical Fiber Cables - High Tensile Performance from China Suppliers and Factory
Product Advantage
The function of the stiffener is to improve the tensile performance 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. Optical cable steel wire needs to be treated, the cost of stainless steel wire is higher, the use of galvanized steel wire not only ensures the process requirements, but also reduces the cost.

Frequently Asked Questions
What is the main function of the stiffener in optical cables?
The primary function of the stiffener is to improve the tensile performance of the optical cable, ensuring it can withstand physical stress during installation and use.
Why is steel wire chosen as a strengthening part?
Steel wire is used because its cost, processing technology, and performance indicators easily meet the stringent production needs and standards of optical cables.
Does the steel wire inside the optical fiber rust easily?
No, the specially treated steel wire used in optical fiber cables is not easy to rust and is designed to prevent any hydrogen damage to the fibers.
Why use galvanized steel wire instead of stainless steel wire?
While stainless steel wire has a higher cost, galvanized steel wire perfectly ensures all process and performance requirements while significantly reducing overall production costs.
What is the strength range of the galvanized steel wire provided?
Depending on the wire diameter (ranging from 0.45mm to 2.77mm), the required strength ranges from 1270 MPA up to 1770 MPA.
