Intensity, while improving overall current-carrying.
Deconcentrator is arranged in mechanical type cage, and deconcentrator ensures that stranded superconducting line is uniformly distributed, it is to avoid order is in disorder, puts
Line tension is uniform.Keep wire order, each position tension force：Cage draw drum tension force is using constant tension system control monofilament
Power；Stranded tension force is controlled by cage with the high accuracy pitch of traction；Subtract side rate before and after mould tension force is crossed by control shaping；Lead
Draw tension is by being pressed into contact with face length and adjusting atmospheric pressure.
Lead mould and twisted bundles shape mould are manufactured using nylon, will not scratch wire, solve superconducting line surface quality
Defect problem.Stranded inclined-plane and guiding surface avoid the right angle contact of stranded superconducting line and mould, reduce stranded superconducting line
Deformation and stress in stranding process.Rounded corner and arc surface further reduce superconducting line surface damage.
Middle superconducting line separates through central conductor hole and the stranded superconducting line of lead mould, stranded superconducting line is protected all the time
Hold stranded around middle superconducting line.
Twisted bundles shape mould uniformly draws stranded superconducting line and middle superconducting line in.
Twisting pitch is controlled by electrical equipment control machinery formula cage rotary rpm and hauling speed uniform.
The high-temperature superconductor twisted wire good mechanical property that this utility model is provided, current load is big.
