Abstract
The present disclosure relates to a cable having reduced loss. Specifically, the present invention relates to a cable having reduced loss that is capable of minimizing the limitation of rated current due to heating of an outer armor and the resultant transmission loss while reducing manufacturing costs and minimizing an outer diameter and weight of the cable.
Claims11
A cable comprising:
- an outer armor formed by cross-winding a plurality of metal wires,
- wherein the metal wires are made of an iron (Fe) alloy including carbon (C), silicon (Si) and manganese (Mn) as alloying elements and a balance of iron (Fe) and unavoidable impurities, the iron (Fe) alloy having a tensile strength of at least 650 MPa and a permeability of less than 200.
2 to 0.5 wt % of silicon (Si), 0.3 to 0.6 wt % of manganese (Mn), 0.05 wt % or less of phosphorus (P), and 0.05 wt % or less of sulfur(S), relative to a total weight of the iron (Fe) alloy.
