Cable Waterblocking

 

In some instances, cables that suffer damage can start to take on water. To eradicate associated problems, a water blocking material should be included during cable manufacture to ensure that damage is minimal, fully contained and is easy to locate and repair. This situation can occur in many different cable types, including telecoms, medium and high voltage, industrial and underwater. Without such water blocking technology, the results of water ingress into the cable can be extremely costly and disruptive.

SAF technology is an ideal absorbent solution for the manufacture of dry water-blocking yarns and nonwoven tapes for internal and external cable applications at risk from moisture exposure. As a fibre it can be easily integrated during tape or yarn manufacture and allows for a smooth, dry finish. Once positioned inside a cable, Should damage occur, such materials rapidly absorb liquid at the point of entry and swell to form a gel preventing any further water or transportation along the length.

Technical Absorbents would be happy to offer advice as to the suitability of its SAF and converted materials for any given cable product/application.
