As industrial quality standards for 2G HTS wire become more and more strict, the focus in the wire development is shifting towards meeting the maximum number of special customer requirements. Each HTS application is implemented through a unique device; therefore, it ideally requires 2G wire with a unique set of properties. The product development at SuperOx is directed towards: (1) customisation of 2G wire itself and (2) fabrication of basic integrated modules made with HTS wires. There are common parameters of the wire, which are critical for almost all applications, such as high Ic value both in magnetic field and in self-field, high mechanical strength, etc. At the same time, in order to offer wire that fits best specific applications, we provide a set of additional wire parameters upon customer demand. SuperOx offers customised wire solutions to reflect different key property profiles sought by the developers of various HTS devices. At present, customisation options include on-demand thickness of silver and copper coatings, surround polyimide insulation, low resistance soldered joints, solder plating, and lamination. We can combine and/or alternate different finishes along the length of a single piece of wire, for example, make a polyimide-insulated wire with ends cleared of insulation coating and pre-soldered to facilitate electric contact. Under development are filamentisation of wires for reduced AC losses, fabrication of stacks of wires, and Roebel cables. In addition to customised wire, we make HTS device modules such as coils (pancake, racetrack, and bifilar) and current leads. Another development are solid 2D blocks of any size and shape consisting of multiple layers of 2G HTS tapes that represent an advanced and easily engineerable alternative to bulk HTS materials for applications that require trapping and/or shielding of magnetic field, including magnetic levitation.
