Cost-effective and Clean Water-Blocking

SAF™ water-blocking yarns can provide cost savings when used as the superabsorbent in power and telecommunication cables. The yarns are supplied on bobbins, which can be sized to suit manufacturing requirements, they are lightweight, easy to onward process and line stops are minimal.

SAF™ yarns can be wrapped around the core and/or placed along the length to protect the whole cable. This negates the need for multiple water-blocking products and so less working capital is tied up in stock.

An independent report has shown that using SAF™ spun yarns can:

  • Reduce water-blocking raw material costs by 35% when used throughout the whole cable
  • Reduce cable weight by circa 90%* compared to using a tape or compound.
  • Dramatically reduce logistic and installation costs, e.g. up to 90% can be saved on installations costs compared to having to prepare and install a ‘wet’ filled cable

*this figure is based on using a SAF™ spun yarn in the first six layers of a power cable core


SAF™ – a soft fibrous superabsorbent – is the key component in all of our fabrics. SAF™ fabrics absorb water and saline rapidly with excellent retention levels. Blood plasma can also be absorbed with greater resistance to solids blocking the surface. The SAF™ content does not shed when the fabrics are being cut and shaped for use. Learn more about SAF™

Fabric selection will be influenced by the final end use, but also many other requirements –absorbency, thickness, durability, and, often most importantly, budget. An experienced development team are on hand to offer advice and help with initial fabric selection for trials. Where possible, bespoke fabrics will be designed and manufactured to meet specific requirements. Contact us for more information

Clean

SAF™ yarns are ideal for smaller vulnerable areas within power and telecommunication cables, where other yarns and tape technologies are often too bulky. As the SAF™ is integrated within the yarn during spinning, there are no dusting issues often associated with powder-coated yarns.

Overall, SAF™ water-blocking yarn technology reduces the mess, and associated maintenance costs, that are common when using a ‘wet’ compound or loose powder. They can also withstand high temperatures sometimes experienced during cable operation.
