Steel wire reinforcement element with adhesive coating and method for its manufacture

Abstract

The invention belongs to the technical field of fiber optical cables, and discloses a steel wire reinforcing element with a bonding coating and a manufacturing method of the steel wire reinforcing element. The method includes the steps of subjecting a steel wire, after paying-off, to the following treatment processes including high frequency preheating, surface treatment, bonding material coating, compensation heating, cooling, diameter and defect detection and traction winding up, to finally obtain a steel wire reinforcing element with a bonding coating. The coated bonding material plays an excellent bi-directional surface bonding role between the steel wire and a sheath material. A rubber-insulated optical cable sheath made with the coated steel wire as a reinforcing element may not easily separated from or slipped relative to a steel wire. The pull resistance performance of an optical cable is good, and stable transmission of optical signals of the optical cable is facilitated. The production process is simple, and the production efficiency is high. The coating method is also applicable in the optical cable field.

Description

technical field [0001] The invention belongs to the field of optical fiber and cable technology, and more specifically relates to a steel wire reinforcing element with an adhesive coating layer and a manufacturing method thereof. Background technique [0002] In recent years, with the continuous advancement of the "triple network integration" strategy at the national level, the optical fiber access network has shown a good momentum of development, and optical fiber access has become a hot spot in the field of optical communication. Because of the simple structure, unique groove design, easy peeling, convenient connection, strong practicability, outstanding bending resistance, and easy laying, the leather optical cable and its various derived structure optical cable products are widely used in the access network. use. [0003] Because the optical fiber is very fragile, non-metallic reinforced components (such as Fiber Reinforced Polymer (FRP)) or metal reinforced components ...
