摘要：
Stabilized seven-core MgB(2) cable has been made from two-axially rolled single-core wires with a Ti/Cu sheath. It was shown that drawing deformation applied prior to braiding influences the core density and consequently also the transport current density, J(c). A proper drawing deformation allows avoiding Jc degradation, and cable critical current density 10(4) A cm(-2) at 9.5 T and 10(5) A cm(-2) at 4.5 T can be reached at 4.2 K.
