Recently, a batch of high-performance semi-conductive water-blocking tape from ONE WORLD successfully passed production and quality inspection, and was delivered to the customer on schedule. This batch of semi-conductive water-blocking tape will be used in a high-voltage cable production project. To ensure performance stability during transportation and storage, all rolls are professionally vacuum-packed, fully guaranteeing product quality.
As a critical functional material in power cables, semi-conductive water-blocking tape plays an indispensable role in high-voltage cable systems. This cable material adopts an innovative composite structure design, using semi-conductive polyester non-woven fabric as the base. Through a precision coating process, high-speed expansion water-absorbent resin, conductive carbon black, and other functional materials are composited, forming an intelligent material system that integrates both conductivity and water-blocking properties. For raw material selection, we insist on using internationally renowned brands, including water-blocking powder from Sumitomo Japan, conductive carbon black from Cabot, and adhesive layers from Dow Chemical, ensuring excellent performance and quality stability from the source and providing solid assurance for customer procurement.
Regarding production technology, we employ a fully automated semi-conductive tape production line covering complete processes including ingredient preparation, coating, vulcanization, and inspection. Among these, the automatic ingredient system precisely weighs, mixes, and disperses raw materials such as carbon black, resin, and water-blocking powder, preparing a uniform and stable semi-conductive slurry. This system supports one-touch formula switching, ensuring absolute accuracy and consistency for every batch. It significantly outperforms manual weighing methods in precision control, production efficiency, and quality consistency, thereby precisely controlling the core properties of semi-conductivity and water-blocking from the source.
In power cable applications, this semi-conductive water-blocking tape provides dual protection. It establishes a reliable equipotential connection between the insulation screen and the metallic sheath, effectively improving electric field distribution. Its unique rapid expansion mechanism enables effective longitudinal water-blocking, significantly limiting the spread of moisture. These dual functions jointly ensure the long-term operational safety and stability of cables in complex environments.
The successful completion of this order fully demonstrates the customer's high recognition of our cable material product quality and service capabilities. ONE WORLD is always committed to providing comprehensive cable material solutions for the wire and cable industry. Our product range includes various high-quality cable materials such as semi-conductive water-blocking tape, mylar tape, water-blocking yarn, XLPE insulation material, and PVC compound. As a professional cable material supplier, we look forward to establishing long-term and stable partnerships with more cable manufacturers, jointly promoting the innovative development of cable material technology and the quality improvement of the power cable industry, to provide better specialized cable material solutions for the global cable industry.
