Abstract
Conductor in strip, sheet or wire form with an electrical conductivity of at least 0.85.times.10.sup.6 .OMEGA..sup.-1 cm.sup.-1 at 77.degree. K. composed of a composite material of a metal matrix (1) and particles (2) composed of a high-temperature superconductor of the type RE Ba.sub.2 Cu.sub.3 O.sub.6.5-7.5 embedded therein and arranged rectilinearly in the longitudinal direction, RE generally denoting a rare earth metal. Preferably RE=yttrium and specifically the substance YBa.sub.2 Cu.sub.3 O.sub.7 and the particle diameter=0.1-100 .mu.m, more narrowly 0.2-20 .mu.m. Optionally an additional metal sheath which envelops the body forming the matrix (1).
