A device and method for sheathing shrink tubing onto materials such as wire, tape, or cables. The device cannot only sheath short lengths of shrink tubing onto material, but also sheath long lengths shrink tubing onto material. Varying embodiments of this device can insulate whole lengths of material with shrink tubing as well as covering certain sections of material for a more precise application.

An electric joint design to be used in electromagnetic coils made with high-temperature superconducting tape, aspected wire, or cable. A terminal member contains an engraved twist-bend contour, which receives the coil and changes the direction of the coil by about 90 degrees without any hard-bends. A current lead is aligned with terminal section of the coil establishing an electric joint whose length is not limited by the coil geometry. Resistance is distributed along the length of the electric joint to reduce heat generation. The electric joint is placed away from the area where the magnetic forces are high to eliminate the problem of helium gas becoming trapped.

A novel method and structure for creating a high-temperature superconducting tape. The concept of the invention is to use a conductor insulation which not only electrically insulates the conductors of the coil windings from each other, but also mechanically insulates them from the much stronger encapsulant. The insulation material mechanically decouples the conductor from the encapsulant at the boundary between them, thereby preventing damage as a result of thermal and electromagnetic shearing forces. The proposed structure allows the encapsulant to continue performing its functions of preventing coarse motion and stabilizing the coil as a whole, while allowing fine relative displacements of individual coil windings caused by radial stress gradients.
