New structural hyperconductive cable is a kind of multistage cable, different from the general nuclear fusion construction of cable, general poly-
The sub- cable of the first order of change cable is made of several copper wire and several superconducting wires according to certain twisting pitch is twisted, so
Several root cable units are constituted into the sub- cable of two level according still further to certain twisting pitch is twisted afterwards, similarly reconstruct three-level, level Four
Cable is finally stranding into Pyatyi cable.Since the void coefficient of cable outer diameters at different levels, cable is affected for the electromagnetic performance of conductor,
Therefore, it is strict for the control requirement of the voidage of the outer diameter of cable, cable during cable process.
Since the structure of novel nuclear fusion hyperconductive cable is different from other structures of fusion hyperconductive cable, such as routinely
Nuclear fusion device carries out process with the method for cable process to new superconductive cable, it is likely that will appear broken string, flattening and outer diameter
The problem of being difficult to reach desired size so that the cable that process goes out cannot be satisfied use condition.
