EIC 2023, the 41st Electrical Insulation Conference sponsored by the IEEE Dielectric and Electrical Insulation Society (DEIS), was held in Quebec City, Canada, June 18 through 21, 2023. Quebec City is the only European-style walled city in North America. It is a beautiful city, rich in history with countless restaurants, pubs, bistros, museums, and shops. We had nearly 200 attendees at the conference from 24 different countries. Over 140 abstracts were initially submitted to EIC 2023 and 96 papers were accepted for final paper presentations.

My ears perked up as the conference speaker lamented the challenges associated with testing spacecraft materials in terrestrial laboratories and wished for a better solution. It was the 2019 Applied Space Environments Conference in Burbank, California, and I was a second-year PhD student at the University of Colorado Boulder at the time. The speaker was discussing how electron sources available in the laboratory are monoenergetic, whereas the space environment contains electrons distributed across a wide range of energies simultaneously. This is unfortunate, as dielectrics and other space materials must undergo significant radiation testing on the ground to determine how they will perform in space. Insulating materials are widely used on spacecraft in cable harnesses, thermal blanketing, and solar array assemblies. When these materials are exposed to the space environment, complex phenomena can occur, such as radiation-induced conductivity and changes in color, all of which depend on the energy of the incident electron irradiation. Though various workarounds have been attempted to deal with the differences between monoenergetic laboratory electron sources and broad-spectrum space radiation, for most materials ground testing is conducted in radiation conditions that are simply not representative of the environment in which those materials operate. As a result, adoption of new, advanced, dielectric materials for space missions is slow, as many space-craft designers prefer to rely on legacy materials that have extensive flight heritage.

On May 11, 2023, China's first 110-kV polypropylene (PP)-insulated cable was successfully put into operation in Guangzhou, and it has been operating safely since then. The 110-kV Pannanyuan transmission line B is located in Liwan District, Guangzhou. The project uses non-crosslinked, eco-type PP-insulated cable. It is the first application of the non-crosslinked, low-carbon, eco-type PP insulation material in the field of high-voltage cables in China. The PP cables are set in a high-voltage line cable tunnel at a depth of 5 m underground, with a total length of 1.47 km. The project was led by China Southern Power Grid Scientific Research Institute.
