PRODUCT DETAILS

FRP strengthen loose tube outdoor cable GYFXTY

The fibers are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. The tube is wrapped with a layer of water blocking and kevlar yarn system. Between the Kevlar yarn and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel FRP are placed at the two sides. The cable is completed with a polyethylene (PE) sheath.
