Corrugated Steel Tape Cables For Mining Duct Direct Burial

GYFA/S/Y unitube loose tube comes with corrugated steel tape armoring, which is suitable for mining, duct and direct burial application. The outer sheath can be produced with PE, LSZH or flame-retardant materials for specific applications. The loose tube armoured fiber optic cable is using a corrugated steel tape strength member and water-blocking fiberglass yarn around the central uni-tube. This kind of reinforcement makes GYFA/S/Y fibre cable excellent performance on crush, tensile resistance, as well as rodent resistance. Therefore, it is usually used in the most demanding and harsh environments.
