Patent ID: 8530390

Claim:
A method for encapsulating a superconductor tape, comprising: a. providing a superconductor tape, including a mechanical substrate bonded to a layer of superconductor material, wherein said superconductor tape has an overall thickness t and an overall width w; b. providing a heat-shrink tubing having a thin wall, said heat-shrink tubing being made of an insulating material having a fractional shrinkage λ s and a pre-shrinkage diameter of d B ; c. selecting said pre-shrinkage diameter of said heat-shrink tubing to conform to the expression 2 π ⁢ ( w + t ) < d B < 2 π ⁢ ( w + t 1 - λ S ) ; d. placing said heat-shrink tubing around said superconductor tape; e. heating said heat shrink tubing to shrink said heat-shrink tubing around said superconductor tape; and f. applying an encapsulant over said heat shrink tubing.
