Nanocomposite Insulation for 2G Superducting Wires
The U.S. Department of Energy, in collaboration with several industry participants, is developing power-distribution systems based on second generation (2G) high-temperature superconducting (HTS) wires. Over the past few years, U.S. industry has made considerable improvements in the electrical performance and the large-scale production of these wires. While wire technology has continued to advance, a critical need has emerged for cost-effective, cryogenically-compatible electrical insulation that can be used in these systems. Dielectric materials for 2G wire applications must be capable of high-voltage, cryogenic temperature operation to ensure the operational reliability of components such as transformers and power transmission lines. To address this need, this project will produce candidate insulation materials and demonstrate their performance under simulated application conditions. Phase I involves the development of nanomaterial-reinforced dielectric materials for use as insulation with 2G superconducting wires. The mechanical, electrical, and thermal performance of the materials will be characterized with regard to the application requirements in power distritubion systems. Commercial Applications and other Benefits as described by the awardee: The market for these insulation materials would include use in motors, generators, and power transmission lines based on 2G wires. These materials also would be directly applicable in motors and other superconducting systems under development by the U.S. Navy. High-performance insulation materials also would be applicable in the automotive, aerospace, and oil and gas industries; in each instance, the customer requires reliable operation under challenging operating conditions.
