HIGH-STRENGTH CONDUCTOR WITH INCREASED CONDUCTIVITY Russian patent published in 1997 - IPC

FIELD: electric engineering, in particular, design of high-pole pulse magnets and heavy-load power transmission lines. SUBSTANCE: device has members which are extended in longitudinal direction and are designed as ribbon fibers which are arranged uniformly in copper matrix along conductor. Ribbon fibers are made from metal or alloy which do not generate inter-metallic compounds with copper. Thickness of ribbon of ribbon fiber is in range of 20 - 1000 nm, distance between fibers in cross section of member is in range of 10 -1 1000 nm. In addition device has at least one insertion which is made from high-purity copper, is located along conductor and is covered with envelope from copper, alloy, which contain copper, or steel. Thickness of insertion is greater than 300 mcm, thickness of envelope is in range of 10 - 200 mcm. Conductivity of resulted conductors is 70 % of conductivity of pure copper. This results in possibility to design pulse magnetic systems for extremely high magnetic fields as well as to build high-strength high-conductivity conductors for electric power transmission lines. Their strength limit is greater than 1000 MPa. EFFECT: increased conductivity. 4 dwg
