Recently, ONE WORLD successfully completed the production and shipment of a batch of yellow Water Blocking Glass Fiber Yarn. This batch of high-performance reinforcement material will be delivered to our long-term partner for the manufacturing of their new generation of All-Dielectric Self-Supporting (ADSS) cables. With its high tensile strength, excellent insulation properties, and outstanding longitudinal water-blocking ability, Water Blocking Glass Fiber Yarn has become an indispensable key reinforcement material in the structures of power cables and optical fiber cables.
This customer has been working with us for many years and has repeatedly purchased our Glass Fiber Yarn, Ripcord, XLPE, and other cable materials, which are widely used in power cable and optical fiber cable projects. In this order, they paid special attention to the performance differences between Water Blocking Glass Fiber Yarn and Standard Glass Fiber Yarn. We also provided them with detailed technical explanations and application recommendations.
Standard Glass Fiber Yarn is known for its high tensile strength and excellent creep resistance. It mainly provides mechanical reinforcement for optical cables and serves as the core strengthening component of the cable structure. Due to its cost-effectiveness, it has become the standard choice for most optical cable products.
In contrast, Water-Blocking Glass Fiber Yarn inherits all the mechanical advantages and dielectric insulation properties of standard glass fiber yarn, while adding a unique active water blocking function through special coating treatment. When the cable sheath is damaged under complex environmental conditions, the yarn rapidly swells upon contact with water and forms a gel-like barrier, effectively preventing water from migrating longitudinally along the cable core and protecting the internal optical fibers from erosion. This feature makes it the preferred solution for direct-buried cables, damp pipeline cables, submarine applications, and ADSS cables used in high-humidity environments.
Meanwhile, our R&D team continuously optimizes the formulation to ensure strong water-blocking performance while maintaining high compatibility with other materials inside the cable, such as filling compounds and jelly. This prevents potential issues such as hydrogen evolution and ensures the long-term transmission stability of optical fibers. Its optimized flexibility also guarantees excellent processing performance on high-speed stranding production lines.
With the rapid development of global optical communication and power networks, the demand for high-performance optical cable materials continues to grow. This shipment is not only a successful product delivery but also a reflection of the long-term trust between us and our customer. We firmly believe that this batch of high-quality Water-Blocking Glass Fiber Yarn will provide strong assurance for the stable operation of the customer's new generation of ADSS cables under harsh conditions.
