A resilient 18x7 IWRC construction using wire tensile ranging from 1770 MPa (115 Long Tons/In2) to 2000 MPa (130 Long Tons/ In2) provide the necessary strength and reliability to operate up to depths of approximately 610m (2000 ft).
A specialized Line Contact Design (LCD) improves performance and reduces internal cross cutting damage, common to other multi-strand products. By combining outer Lang's lay strands with inner regular lay strands, the underside of the outer strand wires run in the same direction as the wires of the supporting layer.
