ROSENDAHL and HV Cable Solutions Oy, a Finland-based engineering and consulting company specialised in power cables and accessories and related materials and manufacturing solutions, have joined forces. Together they are developing high-quality manufacturing solutions for HPTE – high performance thermoplastic elastomers. Over the past few years, HPTE-based power cable insulation systems have gained a lot of attention in the cable industry globally. Due to their excellent electrical behaviour, they provide benefits to production. HPTE provides cable manufacturers with an alternative way to produce medium and high-voltage cables that: • have a higher operating temperature • are recyclable Research published in the journal Nature Communications explains how a newly developed nanophotonic device could be used to upgrade existing networks. Professor Min Gu, from Melbourne’s RMIT University Laboratory of Artificial Intelligence Nanophotonics (LAIN), explained: “The device works by twisting light into a spiral, which allows engineers to create a third dimension for light to carry information. This means we can measure 100 times more information by delivering the signal 100 times faster.” Researchers in the USA have previously created a fibre that could twist light, but Professor Gu’s team is the first to create a reasonably sized detector that can read the information. Professor Gu said the technology could be used to upgrade fibre optic networks such as Australia’s National Broadband Network (NBN). Dr Haoran Ren, from RMIT’s School of Science and a co-author of the paper, said the device could also help with processing large amounts of data. Twisted fibre technology
